Electric multipole moments, topological multipole moment pumping, and chiral hinge states in crystalline insulators

Wladimir A. Benalcazar, B. Andrei Bernevig, and Taylor L. Hughes

Phys. Rev. B 96, 245115 (2017) - Published 11 December, 2017

The Berry phase provides a modern formulation of electric polarization in crystals. Recently, this formulation was extended by the authors to higher electric multipole moments. In quantum mechanical crystalline insulators, such higher multipole moments manifest themselves by the presence of boundary-localized moments of lower dimension. In the presence of certain symmetries, these moments are quantized, and their boundary signatures are fractionalized. Here, the authors elaborate in detail on the theory of higher multipole moments and discuss associated topological pumping phenomena, as well as higher-order topological insulators derived from them.

Unconventional spin dynamics in the honeycomb-lattice material α−RuCl3: High-field electron spin resonance studies

A. N. Ponomaryov, E. Schulze, J. Wosnitza, P. Lampen-Kelley, A. Banerjee, J.-Q. Yan, C. A. Bridges, D. G. Mandrus, S. E. Nagler, A. K. Kolezhuk, and S. A. Zvyagin

Phys. Rev. B 96, 241107(R) (2017) - Published 19 December, 2017

The honeycomb-lattice material α-RuCl3 is a prime candidate for exhibiting Kitaev spin-liquid physics. Here, the authors employ high-field electron spin resonance spectroscopy to probe its spin dynamics across different regions of the phase diagram. Apart from two modes of antiferromagnetic resonance in the zigzag-ordered phase, a rich excitation spectrum was observed in the field-induced quantum disordered state. The authors compare their observations with results of recent numerical calculations, revealing a complex multiparticle nature of magnetic excitations in the field-induced phase.

Electron charge and spin delocalization revealed in the optically probed longitudinal and transverse spin dynamics in n-GaAs

V. V. Belykh, K. V. Kavokin, D. R. Yakovlev, and M. Bayer

Phys. Rev. B 96, 241201(R) (2017) - Published 7 December, 2017

The spin dynamics of localized electrons in solids is drastically different from that of mobile electrons. One of the main features characteristic for localized spins is the prominent difference between the longitudinal and transverse spin relaxation times T1 and T2⋆ in magnetic fields. While up till now these times were believed to be of different nature, here the authors find the surprising relation T1 × T2⋆ ≈ constant for electrons localized on donors in n-GaAs. This is explained by the impact of the magnetic field on spin diffusion. On the other hand, mobile electrons are characterized by a single spin lifetime in the motional-narrowing regime. Upon rising temperature or donor concentration, the authors observe a striking 100-fold increase of T2* due to the onset of motional narrowing.

Phys. Rev. B 96, 241408(R) (2017) - Published 18 December, 2017

Type-II Weyl semimetals (WSM) are topological materials characterized by special Weyl points (WP) in momentum space where the valence and the conduction band touch. A WSM phase is predicted in MoTe2 below 250 K, but the WP located in the unoccupied part of the electronic structure has eluded direct observation. By means of time- and angle-resolved photoemission, the authors reveal the fingerprint of the WP in the ultrafast electron dynamics. Electrons that are optically excited into the conduction band relax faster in the WSM phase than in the high-temperature phase or in the topologically trivial sister compound WTe2.

Deterministic entanglement between a propagating photon and a singlet-triplet qubit in an optically active quantum dot molecule

Y. L. Delley, M. Kroner, S. Faelt, W. Wegscheider, and A. İmamoğlu

Phys. Rev. B 96, 241410(R) (2017) - Published 21 December, 2017

Generation of spin-photon entanglement lies at the heart of quantum repeater protocols. Here, the authors experimentally demonstrate quantum entanglement between a photon and a spin degree of freedom of a quantum dot molecule, by measuring a state overlap with a fully entangled state of about 70%. In contrast to earlier demonstrations of spin-photon entanglement, the system realized here, using single-triplet qubits in a quantum dot molecule, combines potentially long spin-coherence times with a very efficient photonic interface. The authors also develop a novel heterodyne technique that may have wide-ranging applications for characterizing photonic color qubits.

Nodal-line semimetals from Weyl superlattices

Jan Behrends, Jun-Won Rhim, Shang Liu, Adolfo G. Grushin, and Jens H. Bardarson

Phys. Rev. B 96, 245101 (2017) - Published 1 December, 2017

The band crossings at the Fermi level of a Weyl semimetal are generally stable against disorder. The only way to open a gap in the spectrum is by annihilating pairs of Weyl nodes. Here, the authors show that coupling Weyl nodes by a superlattice does not always lead to gap opening, but does lead to a variety of different phases, including a nodal-line semimetal. The authors uncover a novel mechanism that protects the nodal line, a combination of a fractional lattice translation and charge-conjugation symmetry, and show that its in-gap surface states are not necessarily exponentially localized.

Radical chiral Floquet phases in a periodically driven Kitaev model and beyond

Hoi Chun Po, Lukasz Fidkowski, Ashvin Vishwanath, and Andrew C. Potter

Phys. Rev. B 96, 245116 (2017) - Published 12 December, 2017

Chiral topological phases, like quantum Hall states, are characterized by anomalous unidirectional edge transport arising from a nontrivial insulating bulk. Recent developments suggest that they can be extended to periodically driven (Floquet) systems, where quantum information is pumped in lieu of charge or energy. The authors uncover a new chiral Floquet phase of quantum dynamics, whose edge pumps quantized units of fractionalized excitations. These phases are “radical,” in that the quantum dimension pumped is the square root of an integer. Unexpectedly, such edge borders a bulk with dynamical anyon transmutation, demonstrating a novel form of bulk-boundary correspondence.

Intuitive approach to the unified theory of spin relaxation

Lénárd Szolnoki, Balázs Dóra, Annamária Kiss, Jaroslav Fabian, and Ferenc Simon

Phys. Rev. B 96, 245123 (2017) - Published 18 December, 2017

There are two main mechanisms of spin relaxation in conductors. The Elliott-Yafet (EY) mechanism describes spin-flip scattering, while the D’yakonov-Perel’ (DP) mechanism relies on spin precession and motional narrowing. While both need spin-orbit coupling, historically the two mechanisms have been treated differently. It is now demonstrated, using an intuitive generic model, that the two mechanisms can be cast in the same language based on motional narrowing in the presence of an effective, spin-orbit related magnetic field. This shows an intimate relationship between spin flip and spin precession and enables use of the same, readily programmable formalism for both regimes. The technique is demonstrated for MgB2, which shows an anomalous spin-relaxation behavior that cannot be explained by conventional models.

Exciton lifetime and emission polarization dispersion in strongly in-plane asymmetric nanostructures

M. Gawełczyk, M. Syperek, A. Maryński, P. Mrowiński, Ł. Dusanowski, K. Gawarecki, J. Misiewicz, A. Somers, J. P. Reithmaier, S. Höfling, and G. Sęk

Phys. Rev. B 96, 245425 (2017) - Published 27 December, 2017

The authors investigate theoretically and experimentally epitaxial nanostructures offering a full range of confinement regimes for excitons due to controlled cross-sectional sizes and strong variation in the elongation of the nanosize objects - from strong through intermediate to weak confinement. It is demonstrated that the symmetry breaking leads to significantly slower recombination in one of the bright states of the excitonic fine structure. The respective components are detected in time-resolved decays of unpolarized photoluminescence,which allows a full characterization of the exciton states, including their intrinsic polarization properties.

There are two main mechanisms of spin relaxation in conductors. The Elliott-Yafet (EY) mechanism describes spin-flip scattering, while the D’yakonov-Perel’ (DP) mechanism relies on spin precession and motional narrowing. While both need spin-orbit coupling, historically the two mechanisms have been treated differently. It is now demonstrated, using an intuitive generic model, that the two mechanisms can be cast in the same language based on motional narrowing in the presence of an effective, spin-orbit related magnetic field. This shows an intimate relationship between spin flip and spin precession and enables use of the same, readily programmable formalism for both regimes. The technique is demonstrated for MgB2, which shows an anomalous spin-relaxation behavior that cannot be explained by conventional models.

The authors investigate theoretically and experimentally epitaxial nanostructures offering a full range of confinement regimes for excitons due to controlled cross-sectional sizes and strong variation in the elongation of the nanosize objects - from strong through intermediate to weak confinement. It is demonstrated that the symmetry breaking leads to significantly slower recombination in one of the bright states of the excitonic fine structure. The respective components are detected in time-resolved decays of unpolarized photoluminescence,which allows a full characterization of the exciton states, including their intrinsic polarization properties.
