Microscopic definitions of anyon data

Kyle Kawagoe and Michael Levin

Phys. Rev. B 101, 115113 (2020) - Published 9 March, 2020

The algebraic theory of anyons is one of the most powerful tools for studying two-dimensional interacting topological phases of matter. However, despite its success, this formalism is lacking an important conceptual ingredient: concrete, microscopic definitions of the different pieces of ‘anyon data’ that characterize anyon excitations. This paper fills the gap by providing precise operational definitions of every piece of anyon data.

LDA+DMFT approach to resonant inelastic x-ray scattering in correlated materials

Atsushi Hariki, Mathias Winder, Takayuki Uozumi, and Jan Kuneš

Phys. Rev. B 101, 115130 (2020) - Published 18 March, 2020

Motivated by recent improvement of the energy resolution of resonant inelastic x-ray scattering (RIXS), the authors develop a theoretical framework based on the local density approximation and dynamical mean-field theory (LDA+DMFT). It provides a computationally feasible material-specific approach to RIXS spectra in a wide range of materials, including strongly correlated ones. A good agreement with recent experimental data for typical transition-metal oxides is obtained. The relationship of RIXS fluorescencelike features and the electronic structure is explained.

Strained bilayer WSe2 with reduced exciton-phonon coupling

Burak Aslan, Minda Deng, Mark L. Brongersma, and Tony F. Heinz

Phys. Rev. B 101, 115305 (2020) - Published 23 March, 2020

The authors investigate here the influence of strain on bilayer WSe2 using optical reflection and photoluminescence spectroscopy. The linewidth of the A exciton exhibits a significant decrease, from 70 to 36 meV at room temperature under 2.1% strain. They note that this behavior is quite different in monolayer WSe2. They apply the model used earlier on monolayer WSe2 and show that the distinct behavior under strain stems from having different indirect-to-direct gap separations. Their findings are inspiring for utilizing strain for further studies on two-dimensional materials.

Topological models in rotationally symmetric quasicrystals

Callum W. Duncan, Sourav Manna, and Anne E. B. Nielsen

Phys. Rev. B 101, 115413 (2020) - Published 13 March, 2020

The presence and construction of topological states in two-dimensional quasicrystalline models are investigated. Interesting topological states that exist in the bulk but not at the boundary are found for single-particle Hofstadter models on quasicrystalline quasilattices. The destruction of the periodic nature of the Hofstadter butterfly, due to incommensurate fluxes, is demonstrated. Furthermore, the authors describe an approach to construct topologically ordered states for quasicrystals starting from an analytical fractional quantum Hall type wave function.

Quantum limit cyclotron resonance in monolayer epitaxial graphene in magnetic fields up to 560 T: The relativistic electron and hole asymmetry

Daisuke Nakamura, Hiroaki Saito, Hiroki Hibino, Kenichi Asano, and Shojiro Takeyama

Phys. Rev. B 101, 115420 (2020) - Published 17 March, 2020

Electron-hole symmetry breaking of Dirac electrons has been evidenced as a well-resolved cyclotron resonance (CR) peak splitting at magnetic fields around 300-500 T in epitaxial monolayer graphene. The magnetic field was swept up to 560 T for the infrared CR by means of the electromagnetic flux compression technique in a 1000-T class megagauss generator. The authors argue that it is the CR mode repulsion, caused by the electron-electron correlation, which is responsible for the observed CR intensity transfer from the hole to the electron.

Exciton diffusion in monolayer semiconductors with suppressed disorder

Jonas Zipfel, Marvin Kulig, Raül Perea-Causín, Samuel Brem, Jonas D. Ziegler, Roberto Rosati, Takashi Taniguchi, Kenji Watanabe, Mikhail M. Glazov, Ermin Malic, and Alexey Chernikov

Phys. Rev. B 101, 115430 (2020) - Published 30 March, 2020

Monolayer semiconductors with suppressed environmental disorder from encapsulation in high-quality insulators provide a versatile platform to study the propagation of excitonic quasiparticles at ambient conditions. Using time-resolved emission microscopy, the authors monitored linear and nonlinear exciton diffusion in single layers of tungsten disulfide, observing highly mobile excitons with nonmonotonic density dependence of the diffusion. Combining experiment and theory, the authors discuss the impact of multivalley band structure, the role of bound and free charge carriers, the interplay of nonradiative recombination and diffusion as well as the suppressed Auger recombination.

Quantum limit cyclotron resonance in monolayer epitaxial graphene in magnetic fields up to 560 T: The relativistic electron and hole asymmetry

Daisuke Nakamura, Hiroaki Saito, Hiroki Hibino, Kenichi Asano, and Shojiro Takeyama

Phys. Rev. B 101, 115420 (2020) - Published 17 March, 2020

Electron-hole symmetry breaking of Dirac electrons has been evidenced as a well-resolved cyclotron resonance (CR) peak splitting at magnetic fields around 300-500 T in epitaxial monolayer graphene. The magnetic field was swept up to 560 T for the infrared CR by means of the electromagnetic flux compression technique in a 1000-T class megagauss generator. The authors argue that it is the CR mode repulsion, caused by the electron-electron correlation, which is responsible for the observed CR intensity transfer from the hole to the electron.

Monolayer semiconductors with suppressed environmental disorder from encapsulation in high-quality insulators provide a versatile platform to study the propagation of excitonic quasiparticles at ambient conditions. Using time-resolved emission microscopy, the authors monitored linear and nonlinear exciton diffusion in single layers of tungsten disulfide, observing highly mobile excitons with nonmonotonic density dependence of the diffusion. Combining experiment and theory, the authors discuss the impact of multivalley band structure, the role of bound and free charge carriers, the interplay of nonradiative recombination and diffusion as well as the suppressed Auger recombination.
