Screening of tensor properties by magnetic point group symmetries: The PythMPG code package
Andrea Urru, Turan Birol, Trey Cole +1
Understanding the symmetry requirements that permit specific phenomena or physical effects is crucial in condensed matter physics for identifying candidate materials that exhibit o…
Optical spatial dispersion via Wannier interpolation
Andrea Urru, Ivo Souza, Óscar Pozo Ocaña +2
We present a numerical implementation, based on Wannier interpolation, of a Kubo-Greenwood formalism for computing the spatially dispersive optical conductivity in crystals at firs…
Engineering magnetic topological insulators in Eu Zintls
Nicodemos Varnava, Tanya Berry, Tyrel M. McQueen +1
Magnetic topological insulator provide a prominent material platform for quantum anomalous Hall physics and axion electrodynamics. However, the lack of material realizations with c…
First principles theory of Dirac semimetal CdAs under Zeeman magnetic field
Santu Baidya, David Vanderbilt
Time-reversal broken Weyl semimetals have attracted much attention recently, but certain aspects of their behavior, including the evolution of their Fermi surface topology and anom…
Gapless hinge states from adiabatic pumping of axion coupling
Thomas Olsen, Tomáš Rauch, David Vanderbilt +1
We demonstrate that chiral hinge modes naturally emerge in insulating crystals undergoing a slow cyclic evolution that changes the Chern-Simons axion angle by . This happen…
Robust A-type order and spin-flop transition on the surface of the antiferromagnetic topological insulator MnBiTe
Paul M. Sass, Jinwoong Kim, David Vanderbilt +2
Here we present microscopic evidence of the persistence of uniaxial A-type antiferromagnetic order to the surface layers of MnBiTe single crystals using magnetic force micr…
