Generalized Kohn-Sham Approach for the Electronic Band Structure of Spin-Orbit Coupled Materials
Jacques K. Desmarais, Giacomo Ambrogio, Giovanni Vignale +2
Spin-current density functional theory (SCDFT) is a formally exact framework designed to handle the treatment of interacting many-electron systems including spin-orbit coupling at…
D4FT: A Deep Learning Approach to Kohn-Sham Density Functional Theory
Tianbo Li, Min Lin, Zheyuan Hu +6
Kohn-Sham Density Functional Theory (KS-DFT) has been traditionally solved by the Self-Consistent Field (SCF) method. Behind the SCF loop is the physics intuition of solving a syst…
Frequency-dependent Faraday and Kerr rotation in anisotropic nonsymmorphic Dirac semimetals
Amarnath Chakraborty, Guang Bian, Giovanni Vignale
We calculate the frequency-dependent longitudinal and Hall conductivities and the Faraday and Kerr rotation angles for a single sheet of anisotropic Dirac semimetal protected by no…
Non-conservation of the valley density and its implications for the observation of the valley Hall effect
Alexander Kazantsev, Amelia Mills, Eoin O'Neill +3
We show that the conservation of the valley density in multivalley insulators is broken in an unexpected way by the electric field that drives the valley Hall effect. This implies…
Anomalous skew-scattering nonlinear Hall effect and chiral photocurrents in {\it PT}-symmetric antiferromagnets
Da Ma, Arpit Arora, Giovanni Vignale +1
Berry curvature and skew-scattering play central roles in determining both the linear and nonlinear anomalous Hall effects. Yet in {\it PT}-symmetric antiferromagnetic metals, Hall…
High conductivity from cross-band electron pairing in flat-band systems
Maxim Trushin, Liangtao Peng, Gargee Sharma +2
Electrons in condensed matter may transition into a variety of broken-symmetry phase states due to electron-electron interactions. Applying diverse mean-field approximations to the…
