Carrier dynamics in doped bilayer iridates near magnetic quantum criticality

Shouryya Ray and Matthias Vojta

Phys. Rev. B 98, 115102 (2018) - Published 4 September, 2018

Iridium oxide compounds form a fascinating class of materials, as their electronic properties are characterized by the simultaneous presence of strong electron-electron repulsion and strong spin-orbit coupling. Recent photoemission experiments on the carrier-doped bilayer iridate (Sr1xLax)3Ir2O7 have shown the presence of small double Fermi pockets. Here, the authors provide a theoretical description of the dynamics of doped electrons in bilayer magnets in the presence of spin-orbit coupling, focusing on the vicinity of the magnetic bilayer quantum critical point. For experimentally relevant parameters, the combination of octahedral rotation and spin-orbit coupling induces a band folding that results in a Fermi surface of small double electron pockets, in striking agreement with experiment.

Geometric and nongeometric contributions to the surface anomalous Hall conductivity

Tomáš Rauch, Thomas Olsen, David Vanderbilt, and Ivo Souza

Phys. Rev. B 98, 115108 (2018) - Published 5 September, 2018

A static electric field generates circulating currents at the surfaces of a magnetoelectric insulator. Remarkably, the anomalous Hall (transverse) part of the surface conductivity can change by multiples of e2/h depending on the insulating surface preparation, and a bulk calculation does not fix its quantized part. To resolve this ambiguity, the authors have developed a formalism for calculating the full surface anomalous Hall conductivity in a slab geometry. They identified a Berry-curvature term whose value can change by quantized amounts by adjusting the surface Hamiltonian, and a nongeometric term that does not depend on the surface preparation.

Quantitative evaluation of Dirac physics in PbTe

Kazuto Akiba, Atsushi Miyake, Hideaki Sakai, Keisuke Katayama, Hiroshi Murakawa, Noriaki Hanasaki, Sadao Takaoka, Yoshiki Nakanishi, Masahito Yoshizawa, and Masashi Tokunaga

Phys. Rev. B 98, 115144 (2018) - Published 24 September, 2018

Exploration of novel macroscopic responses stemming from relativistic Dirac fermions in materials has become popular in condensed matter physics. Here, the authors carefully analyze the quantum oscillations in PbTe and evaluate the ratio of the Zeeman to the cyclotron energy, which has been proposed as a macroscopic index to find how close the system is to the ideal two-band Dirac system. The results remind us of the importance of the trivial phase shift by Zeeman splitting when considering the nontrivial Berry phase from quantum oscillations in topological materials.

Inclusion-exclusion principle for many-body diagrammatics

Aviel Boag, Emanuel Gull, and Guy Cohen

Phys. Rev. B 98, 115152 (2018) - Published 26 September, 2018

Diagrammatic resummation techniques have recently enabled new classes of quantum Monte Carlo algorithms, but are restricted by the need to sum over factorially large sets of diagrams. Here, the authors present a fast algorithm for summing over the diagrams appearing in Inchworm hybridization expansions. The method relies on the inclusion-exclusion principle to reduce the scaling from factorial to exponential. For the Inchworm hybridization expansion, when compared to the previous state of the art, the new algorithm is shown to provide practical performance gains of approximately two orders of magnitude.

Phys. Rev. B 98, 115157 (2018) - Published 27 September, 2018

The authors investigate the properties of a two-dimensional Kondo lattice represented by a noncentrosymmetric Si-Ir-Si-Yb four-layer block at the surface of the heavy-fermion material YbIr2Si2. Strong spin-orbit coupling of Ir atoms induces spin polarization of two-dimensional itinerant surface states confined in this block, while the lattice of Yb 4f moments acts as a source for coherent field interplay. Remarkably, apart from the anticipated Rashba-like splitting of the two-dimensional itinerant states, a tiny spin splitting of the Yb 4f states of the block is also revealed. Electrons in these 4f states interact in a temperature-dependent fashion with highly mobile spin-polarized itinerant states, gently guiding their properties.

Electronic fingerprints of Cr and V dopants in the topological insulator Sb2Te3

Wenhan Zhang, Damien West, Seng Huat Lee, Yunsheng Qiu, Cui-Zu Chang, Jagadeesh S. Moodera, Yew San Hor, Shengbai Zhang, and Weida Wu

Phys. Rev. B 98, 115165 (2018) - Published 28 September, 2018

Ferromagnetic domain behavior has been recently reported in Cr and V codoped topological insulator (TI) films using magnetic imaging, providing direct evidence for long-range ferromagnetic order. The observed robust ferromagnetism explains the significant increase in the anomalous quantum Hall effect (AQHE) in the codoped magnetic TI thin films. To understand the mechanism of such enhancement, it is imperative to investigate the spatial distribution of magnetic dopants and their defect states. Here, the authors report electronic fingerprints of the magnetic dopants Cr and V in Sb2Te3 single crystals using spectroscopy imaging. These results have been reproduced in thin films synthesized by molecular beam epitaxy, which facilitates follow-up investigation of the mechanisms of robust ferromagnetic order and AQHE in Cr and V codoped TI films.

Strain tuning of excitons in monolayer WSe2

Burak Aslan, Minda Deng, and Tony F. Heinz

Phys. Rev. B 98, 115308 (2018) - Published 27 September, 2018

The authors investigate the influence of strain on the electronic properties of monolayer WSe2 using optical absorption and photoluminescence spectroscopy. The linewidth of the A exciton exhibits a significant and unexpected decrease, from 42 to 24 meV at room temperature. A slightly different behavior is observed for WS2; its linewidth decreases from 30 to 24 meV. They provide a model that explains both the decrease in linewidth and differences in the magnitude of the effect in these two similar material systems. Their findings reveal the utility of strain tuning for probing subtle aspects of 2D materials.

The authors investigate the influence of strain on the electronic properties of monolayer WSe2 using optical absorption and photoluminescence spectroscopy. The linewidth of the A exciton exhibits a significant and unexpected decrease, from 42 to 24 meV at room temperature. A slightly different behavior is observed for WS2; its linewidth decreases from 30 to 24 meV. They provide a model that explains both the decrease in linewidth and differences in the magnitude of the effect in these two similar material systems. Their findings reveal the utility of strain tuning for probing subtle aspects of 2D materials.
