Dark excitations in monolayer transition metal dichalcogenides

Thorsten Deilmann and Kristian Sommer Thygesen

Phys. Rev. B 96, 201113(R) (2017) - Published 27 November, 2017

To date, most studies on electronic excitations in 2D materials have focused on the optically active excitations, but recent experiments have highlighted the existence of dark states, which are equally important in many respects. Here, the authors use ab initio many-body calculations to unravel the nature of the dark excitations in monolayer MoSe2, MoS2, WSe2, and WS2. The lowest neutral and charged excitations are found to be dark. In accordance with experiment, dark trions are weaker bound than bright trions.

Valley surface-wave photonic crystal and its bulk/edge transport

Zhen Gao, Zhaoju Yang, Fei Gao, Haoran Xue, Yahui Yang, Jianwen Dong, and Baile Zhang

Phys. Rev. B 96, 201402(R) (2017) - Published 6 November, 2017

The valley Hall effect and topological valley edge states are two fundamental properties in gapped valleytronic materials, such as MoS2 and biased bilayer graphene. Such properties have paved the way for applications in valleytronics. Here, the authors experimentally demonstrate a valley surface-wave photonic crystal on a single metal surface, as the photonic analog of the valley-Hall topological insulator phase. The photonic valley-Hall effect with valley-chirality locked beam splitting, and topological valley-polarized edge states, are demonstrated for the first time on a photonic platform.

Sheng-Jie Huang, Hao Song, Yi-Ping Huang, and Michael Hermele

Phys. Rev. B 96, 205106 (2017) - Published 6 November, 2017

Topological phases protected by the geometrical symmetries of crystal lattices turn out to be surprisingly simple. They can be built from simpler lower-dimensional states, arranged in a crystalline pattern.

Topological edge-state engineering with high-frequency electromagnetic radiation

Mehedi Hasan, Dmitry Yudin, Ivan Iorsh, Olle Eriksson, and Ivan Shelykh

Phys. Rev. B 96, 205127 (2017) - Published 15 November, 2017

Strong interaction with light may modify quantitatively the electronic properties of condensed matter systems. Here, the authors consider the classical example of topological electron states in a CdTe/HgTe/CdTe heterostructure and demonstrate that the coupling between electrons in a two-dimensional region and an external electromagnetic wave controls with high accuracy the normal and topological phases in the system. The electromagnetic radiation also modifies the properties of the edge states, which leads to the reversal of the edge spin currents. Importantly, all these effects can be realized in controllable and reversible way, and this has high potential impact for their integration of spintronics and optoelectronics.

Quantized charge transport in chiral Majorana edge modes

Stephan Rachel, Eric Mascot, Sagen Cocklin, Matthias Vojta, and Dirk K. Morr

Phys. Rev. B 96, 205131 (2017) - Published 16 November, 2017

Lattices of magnetic adatoms deposited on the surface of s-wave superconductors (Shiba lattices) have been proposed as a new platform for topological superconductivity, allowing for the local manipulation and detection of Majorana modes via scanning-probe techniques. The authors demonstrate that the topological Majorana edge modes of nanoscopic Shiba islands display universal electronic and transport properties. Most remarkably, these Majorana modes possess a quantized charge conductance that is proportional to the topological Chern number (C), and carry a supercurrent whose chirality reflects the sign of C. These results establish nanoscopic Shiba islands as promising components in future topology-based devices.

Optical conductivity of a two-dimensional metal near a quantum critical point: The status of the extended Drude formula

Andrey V. Chubukov and Dmitrii L. Maslov

Phys. Rev. B 96, 205136 (2017) - Published 20 November, 2017

This paper is devoted to the analysis of the frequency dependence of the optical conductivity, σ′(Ω), of a metal near a quantum critical point (QCP). According to general reasoning, the frequency dependence of σ′(Ω) may come via the scattering time and the effective mass, m⋆, but not via the quasiparticle residue Z, because the conductivity probes quasiparticles rather than bare electrons. However, in local theories of QCPs, m⋆/m, coincides with 1/Z, and it is not straightforward to separate the two quantities. The authors use a direct diagrammatic approach, in which m⋆/m and Z are treated separately. They compute the optical conductivity σ′(Ω) near two-dimensional nematic and spin-density wave (SDW) QCPs. They explicitly demonstrate that the Z factor is canceled out by series of vertex corrections, and m⋆/m does not appear separately from Z. As a result, σ′(Ω) diverges as 1/Ω2/3 in the nematic case and as 1/Ω (up to logarithmic factors) in the SDW case.

Nuclear spin cooling by helicity-alternated optical pumping at weak magnetic fields in n-GaAs

Phys. Rev. B 96, 205205 (2017) - Published 28 November, 2017

Optical cooling of a mesoscopic nuclear spin ensemble in a semiconductor is a complex process that involves transferring angular momentum and energy between nuclear spins and optically oriented localized electrons. The established spin temperature is sensitive to the balance between pumping and losses as well as to the heat capacity of the nuclear spin ensemble. This property allows one to determine the zero-frequency value of the correlator of nuclear spin fluctuations and thus to estimate the spin-spin relaxation time T2 at low magnetic fields from the frequency response of the electron-nuclear spin ensemble to a modulated optical pumping.

Electron teleportation and statistical transmutation in multiterminal Majorana islands

Karen Michaeli, L. Aviad Landau, Eran Sela, and Liang Fu

Phys. Rev. B 96, 205403 (2017) - Published 1 November, 2017

Majorana zero modes are localized zero-energy degrees of freedom in topological superconductors that can store quantum information in a protected manner. Finding a direct proof of the Majorana identity of zero-energy states has been a challenge. The authors show that, in a Coulomb blockaded superconductor island coupled to normal metal leads, Majorana zero modes on the island bind with electrons in the leads to form a charge-e boson, thereby converting the quantum statistics of charge carriers. This statistical transmutation leads to unusual temperature and voltage dependence of the tunneling current as a unique signature of the Majorana zero modes.

Microscopic origin of the Drude-Smith model

Phys. Rev. B 96, 205439 (2017) - Published 27 November, 2017

Terahertz spectroscopy of nanomaterials is one of the most active areas of terahertz physics thanks to its ability to reveal charge-carrier confinement on length scales of tens to hundreds of nanometers. Structural confinement modifies the experimental complex conductivity, such that it is Drude-like at high frequencies but suppressed at low frequencies. This response is often described as a consequence of carrier backscattering off nanoparticle boundaries and modeled using the sometimes controversial Drude-Smith formula. In this paper, it is demonstrated that the terahertz conductivity of a structurally confined Drude gas of electrons is actually suppressed at low frequencies due to carrier confinement on the diffusion length scale and not due to backscattering. A new conductivity formula is derived based on diffusion that is found to be very similar to the Drude-Smith conductivity formula, thereby explaining many of the previous successes of the Drude-Smith model.

Fermi arc plasmons in Weyl semimetals

Justin C. W. Song and Mark S. Rudner

Phys. Rev. B 96, 205443 (2017) - Published 29 November, 2017

Weyl semimetals, prototypical three dimensional topological metals, possess a unique band structure that has enriched the “standard model” of metallic behavior. This work unveils how the unusual topological surface states of Weyl semimetals radically alter their plasmonic characteristics, yielding intrinsic hyperbolic surface plasmons. These Fermi-arc plasmons have a rich phenomenology, and arise from the coupled dynamics of carriers both on the unusual open-segment surface Fermi arc and the bulk Fermi surface, clearly demonstrating the intricate interplay of bulk and surface. While Fermi-arc plasmons are fascinating in their own right, the essential role that the open-segment Fermi arcs play also indicates more broadly that Weyl semimetals may host new types of interacting phenomena not realizable in conventional metals − an exciting prospect for future developments.

According to general reasoning, the frequency dependence of σ′(Ω) may come via the scattering time and the effective mass, m⋆, but not via the quasiparticle residue Z, because the conductivity probes quasiparticles rather than bare electrons. However, in local theories of QCPs, m⋆/m, coincides with 1/Z, and it is not straightforward to separate the two quantities. The authors use a direct diagrammatic approach, in which m⋆/m and Z are treated separately. They compute the optical conductivity σ′(Ω) near two-dimensional nematic and spin-density wave (SDW) QCPs. They explicitly demonstrate that the Z factor is canceled out by series of vertex corrections, and m⋆/m does not appear separately from Z. As a result, σ′(Ω) diverges as 1/Ω2/3 in the nematic case and as 1/Ω (up to logarithmic factors) in the SDW case.

Optical cooling of a mesoscopic nuclear spin ensemble in a semiconductor is a complex process that involves transferring angular momentum and energy between nuclear spins and optically oriented localized electrons. The established spin temperature is sensitive to the balance between pumping and losses as well as to the heat capacity of the nuclear spin ensemble. This property allows one to determine the zero-frequency value of the correlator of nuclear spin fluctuations and thus to estimate the spin-spin relaxation time T2 at low magnetic fields from the frequency response of the electron-nuclear spin ensemble to a modulated optical pumping.

Majorana zero modes are localized zero-energy degrees of freedom in topological superconductors that can store quantum information in a protected manner. Finding a direct proof of the Majorana identity of zero-energy states has been a challenge. The authors show that, in a Coulomb blockaded superconductor island coupled to normal metal leads, Majorana zero modes on the island bind with electrons in the leads to form a charge-e boson, thereby converting the quantum statistics of charge carriers. This statistical transmutation leads to unusual temperature and voltage dependence of the tunneling current as a unique signature of the Majorana zero modes.

Terahertz spectroscopy of nanomaterials is one of the most active areas of terahertz physics thanks to its ability to reveal charge-carrier confinement on length scales of tens to hundreds of nanometers. Structural confinement modifies the experimental complex conductivity, such that it is Drude-like at high frequencies but suppressed at low frequencies. This response is often described as a consequence of carrier backscattering off nanoparticle boundaries and modeled using the sometimes controversial Drude-Smith formula. In this paper, it is demonstrated that the terahertz conductivity of a structurally confined Drude gas of electrons is actually suppressed at low frequencies due to carrier confinement on the diffusion length scale and not due to backscattering. A new conductivity formula is derived based on diffusion that is found to be very similar to the Drude-Smith conductivity formula, thereby explaining many of the previous successes of the Drude-Smith model.

Fermi arc plasmons in Weyl semimetals

Phys. Rev. B 96, 205443 (2017) - Published 29 November, 2017

Weyl semimetals, prototypical three dimensional topological metals, possess a unique band structure that has enriched the “standard model” of metallic behavior. This work unveils how the unusual topological surface states of Weyl semimetals radically alter their plasmonic characteristics, yielding intrinsic hyperbolic surface plasmons. These Fermi-arc plasmons have a rich phenomenology, and arise from the coupled dynamics of carriers both on the unusual open-segment surface Fermi arc and the bulk Fermi surface, clearly demonstrating the intricate interplay of bulk and surface. While Fermi-arc plasmons are fascinating in their own right, the essential role that the open-segment Fermi arcs play also indicates more broadly that Weyl semimetals may host new types of interacting phenomena not realizable in conventional metals − an exciting prospect for future developments.
