Tunable axial gauge fields in engineered Weyl semimetals: Semiclassical analysis and optical lattice implementations
Sthitadhi Roy, Michael Kolodrubetz, Nathan Goldman +1
In this work, we describe a toolbox to realize and probe synthetic axial gauge fields in engineered Weyl semimetals. These synthetic electromagnetic fields, which are sensitive to…
Chern numbers and chiral anomalies in Weyl butterflies
Sthitadhi Roy, Michael Kolodrubetz, Joel E. Moore +1
The Hofstadter butterfly of lattice electrons in a strong magnetic field is a cornerstone of condensed matter physics, exploring the competition between periodicities imposed by th…
Wavepacket dynamics on Chern band lattices in a trap
Sthitadhi Roy, Adolfo G. Grushin, Roderich Moessner +1
The experimental realization of lattices with Chern bands in ultracold-atom and photonic systems has motivated the study of time-dependent phenomena, such as spatial propagation, i…
Response of fermions in Chern bands to spatially local quenches
Adolfo G. Grushin, Sthitadhi Roy, Masudul Haque
We study the dynamical evolution of Chern-band systems after subjecting them to local quenches. For open-boundary systems, we show for half-filling that the chiral nature of edge s…
