Model for the metal-insulator transition in graphene superlattices and beyond

Noah F. Q. Yuan and Liang Fu

Phys. Rev. B 98, 045103 (2018) - Published 3 July, 2018

In bilayer graphene with a small twist angle, the moiré pattern creates a superlattice with over 10000 atoms per supercell and complex minibands with a small bandwidth. The low-energy narrow bands host correlated insulating and unconventional superconducting phases discovered recently. Here, the authors introduce a two-orbital tight-binding and Hubbard model on a honeycomb lattice to capture the physics of these narrow bands. This model provides a starting point for studying the metal-insulator transition, Landau level degeneracy lifting, and superconductivity in twisted bilayer graphene.

Topological order from disorder and the quantized Hall thermal metal: Possible applications to the ν=5/2 state

Chong Wang, Ashvin Vishwanath, and Bertrand I. Halperin

Phys. Rev. B 98, 045112 (2018) - Published 9 July, 2018

This work addresses the apparent discrepancy between the recent observation of a quantized thermal conductance with thermal quantum number K=5/2 in the quantum Hall state at filling fraction n=5/2 and the numerical simulations of the same system during the past two decades. The authors show that under certain conditions a quantized phase with K=5/2 could be stabilized by disorder, a direction not previously appreciated, but under other conditions (such as an altered disorder strength) disorder could lead to a new exotic phase with quantized electrical conductance, yet with metallic thermal conduction, which the authors term a “quantized Hall thermal metal.”

Observation of a Dirac nodal line in AlB2

Daichi Takane, Seigo Souma, Kosuke Nakayama, Takechika Nakamura, Hikaru Oinuma, Kentaro Hori, Kouji Horiba, Hiroshi Kumigashira, Noriaki Kimura, Takashi Takahashi, and Takafumi Sato

Phys. Rev. B 98, 041105(R) (2018) - Published 17 July, 2018

The authors present measurements by soft-x-ray angle-resolved photoemission spectroscopy of hexagonal diboride AlB2, which is a cousin material of the well-known high-temperature superconductor MgB2. Via accurate determination of the three-dimensional bulk band structure corroborated by first-principles band-structure calculations, the authors demonstrate that AlB2 displays an exotic Dirac-nodal-line structure with anisotropic Dirac-cone energy band. This intriguing electronic structure provides an excellent platform to study the interplay among the line node, low-energy excitations, and topological transport properties.

Equipartition of the entanglement entropy

J. C. Xavier, F. C. Alcaraz, and G. Sierra

Phys. Rev. B 98, 041106(R) (2018) - Published 17 July, 2018

The authors present a derivation of finite-size corrections to entanglement entropies that possess an internal symmetry. They show that entanglement entropy is equally distributed among the different sectors of that internal symmetry. Its value is given by the standard area-law-violating logarithmic term, which depends on the central charge c, minus a double logarithmic correction related to the zero-temperature susceptibility. They present a very efficient way to determine the central charge and the Luttinger parameter. This opens the possibility that the measurement of these quantities can be successfully pursued in an optical lattice. The analytical predictions are verified against numerical results obtained by DMRG.

Revealing the hidden heavy Fermi liquid in CaRuO3

Yang Liu, Hari P. Nair, Jacob P. Ruf, Darrell G. Schlom, and Kyle M. Shen

Phys. Rev. B 98, 041110(R) (2018) - Published 25 July, 2018

CaRuO3 has long been an enigmatic compound due to reports of possible non-Fermi-liquid behavior and its proximity to a magnetic quantum critical point. Through a combination of molecular beam epitaxy growth and angle-resolved photoemission, the authors reveal that the large rotations of the RuO6 octahedra result in a complex Fermi surface with multiple quasiparticle bands and hybridization gaps lying very close to the Fermi energy. The measurements demonstrate a highly band-dependent mass renormalization, where the dispersion and temperature dependence of the heavy bands show intriguing parallels to heavy-fermion systems. These results provide a unified framework for explaining the peculiar properties of CaRuO3 and demonstrate the importance of octahedral rotations in shaping the physical properties of the ruthenates.

Anomalous modulation of Josephson radiation in nanowire-based Josephson junctions

H. Kamata, R. S. Deacon, S. Matsuo, K. Li, S. Jeppesen, L. Samuelson, H. Q. Xu, K. Ishibashi, and S. Tarucha

Phys. Rev. B 98, 041302(R) (2018) - Published 19 July, 2018

In contrast to recent rapid progress with measurements in the search for Majorana fermions, the observation of a 4π-periodic Josephson effect, which would provide further experimental evidence for them, still remains a challenge for the field of nanowire-based systems. In this paper, the authors investigate quantitatively the ac Josephson effect in nanowire-based Josephson junctions. They observe anomalous modulation of the Josephson radiation in a finite magnetic field. The modulation can be explained by a change in circuit impedance.

Ultrafast terahertz field control of electronic and structural interactions in vanadium dioxide

A. X. Gray et al.

Phys. Rev. B 98, 045104 (2018) - Published 2 July, 2018

In this study, the authors show that multiple interrelated processes in the nonequilibrium electronic and structural dynamics in vanadium dioxide can be disentangled experimentally in the time domain. This is accomplished by using both near-infrared and hard x-ray pulses to track the dynamics following excitation with an intense nonresonant terahertz pulse, which initiates the insulator-metal transition. Electronic structure switching is observed to be virtually simultaneous with the subpicosecond metamaterial-enhanced terahertz pulse; it is induced by electric-field-assisted tunneling of valence electrons into the conduction band. For sufficiently high electric fields, this triggers the onset of the full transition to the rutile metallic state.

Evidence for a topological “exciton Fermi sea” in bilayer graphene

Michael P. Zaletel, Scott Geraedts, Zlatko Papić, and Edward H. Rezayi

Phys. Rev. B 98, 045113 (2018) - Published 9 July, 2018

The authors report on the discovery of a new state of matter, a topological exciton Fermi sea, which is found to live in bilayer graphene. There, the nature of the fractionalized quantum Hall states at suitable fillings provides for the emergence of nontrivial fermionic excitons in addition to the usual bosonic ones, made of bound electron-hole pairs.

Charge density wave phase, Mottness, and ferromagnetism in monolayer 1T−NbSe2

Diego Pasquier and Oleg V. Yazyev

Phys. Rev. B 98, 045114 (2018) - Published 10 July, 2018

The metastable 1T polymorph of NbSe2 was recently successfully synthesized in monolayer form. The observation of a superlattice and insulating behavior suggests an analogy with 1T-TaS2, an extensively investigated system known for its complex phase diagram that has recently been suggested to realize a possible quantum spin-liquid ground state. Here, a series of ab initio techniques, from density functional theory (DFT) to dynamical mean-field theory (DMFT), finds that the star-of-David phase in 1T-NbSe2 is the most stable commensurate charge density wave phase and that its electronic character is a Mott insulator. DFT calculations also predict weak nearest-neighbor ferromagnetic coupling, which would disfavor a quantum spin liquid phase but suggest a flat-band ferromagnetism scenario.

Classical and quantum spin dynamics of the honeycomb Γ model

Anjana M. Samarakoon, Gideon Wachtel, Youhei Yamaji, D. A. Tennant, Cristian D. Batista, and Yong Baek Kim

Phys. Rev. B 98, 045121 (2018) - Published 16 July, 2018

The spin of an electron is an inherently quantum-mechanical object as it is quantized as half-integer values in the unit of the Planck’s constant. Indeed, a variety of magnetism phenomena arising from interacting spins in crystalline solids are direct consequences of this quantization. Yet the present study reveals that the classical dynamics of spins in frustrated magnets with strong spin-orbit coupling can describe their quantum dynamics at finite temperature. The authors show that this peculiar classical-quantum correspondence originates from the constraints on the relativemotion of spins on the crystalline lattice.

The spin of an electron is an inherently quantum-mechanical object as it is quantized as half-integer values in the unit of the Planck’s constant. Indeed, a variety of magnetism phenomena arising from interacting spins in crystalline solids are direct consequences of this quantization. Yet the present study reveals that the classical dynamics of spins in frustrated magnets with strong spin-orbit coupling can describe their quantum dynamics at finite temperature. The authors show that this peculiar classical-quantum correspondence originates from the constraints on the relativemotion of spins on the crystalline lattice.
