Phase diagram of the interacting persistent spin-helix state
Hong Liu, Weizhe Edward Liu, Stefano Chesi +2
We study the phase diagram of the interacting two-dimensional electron gas (2DEG) with equal Rashba and Dresselhaus spin-orbit coupling, which for weak coupling gives rise to the w…
Weak Localization and Antilocalization in Topological Materials with Impurity Spin-Orbit Interactions
Weizhe Edward Liu, Ewelina M. Hankiewicz, Dimitrie Culcer
Topological materials have attracted considerable experimental and theoretical attention. They exhibit strong spin-orbit coupling both in the band structure (intrinsic) and in the…
A generalized Stoner criterion and versatile spin ordering in two-dimensional spin-orbit coupled electron systems
Weizhe Edward Liu, Stefano Chesi, David Webb +4
Spin-orbit coupling is a single-particle phenomenon known to generate topological order, and electron-electron interactions cause ordered many-body phases to exist. The rich interp…
Quantum Transport in Weyl Semimetal Thin Films in the Presence of Spin-Orbit Coupled Impurities
Weizhe Edward Liu, Ewelina M. Hankiewicz, Dimitrie Culcer
Topological semimetals have been at the forefront of experimental and theoretical attention in condensed matter physics. Among these, recently discovered Weyl semimetals have a dis…
Anomalous Hall Coulomb drag of massive Dirac fermions
Hong Liu, Weizhe Edward Liu, Dimitrie Culcer
Dirac fermions are actively investigated, and the discovery of the quantized anomalous Hall effect of massive Dirac fermions has spurred the promise of low-energy electronics. Some…
Coulomb drag in topological insulator films
Hong Liu, Weizhe Edward Liu, Dimitrie Culcer
We study Coulomb drag between the top and bottom surfaces of topological insulator films. We derive a kinetic equation for the thin-film spin density matrix containing the full spi…
Conductivity Corrections for Topological Insulators with Spin-Orbit Impurities: A New Hikami-Larkin-Nagaoka Formula
P. Adroguer, Weizhe E. Liu, D. Culcer +1
The Hikami-Larkin-Nagaoka (HLN) formula [Prog. Theor. Phys. 63, 707 (1980)] describes the quantum corrections to the magnetoconductivity of a quasi-2D electron gas (quasi-2DEG) wit…
Screening, Friedel oscillations and low-temperature conductivity in topological insulator thin films
Weizhe Edward Liu, Hong Liu, Dimitrie Culcer
In thin topological insulator films, the top and bottom surfaces are coupled by tunneling, which restores backscattering and strongly affects screening. We calculate the dielectric…
