Surface theorem for the Chern-Simons axion coupling
Thomas Olsen, Maryam Taherinejad, David Vanderbilt +1
The Chern-Simons axion coupling of a bulk insulator is only defined modulo a quantum of e^2/h. The quantized part of the coupling is uniquely defined for a bounded insulating sampl…
Z2Pack: Numerical Implementation of Hybrid Wannier Centers for Identifying Topological Materials
Dominik Gresch, Gabriel Autès, Oleg V. Yazyev +4
The intense theoretical and experimental interest in topological insulators and semimetals has established band structure topology as a fundamental material property. Consequently,…
Domain walls and ferroelectric reversal in corundum derivatives
Meng Ye, David Vanderbilt
Domain walls are the topological defects that mediate polarization reversal in ferroelectrics, and they may exhibit quite different geometric and electronic structures compared to…
Temperature effects in the band structure of topological insulators
Bartomeu Monserrat, David Vanderbilt
We study the effects of temperature on the band structure of the BiSe family of topological insulators using first-principles methods. Increasing temperature drives these m…
