Sound Induced Hall Currents in Weyl Exciton Insulators
Xinhong Zhou, Varsha Subramanyan, Qing-Dong Jiang
Weyl semimetals exhibit anomalous transport controlled by their gapless chiral nodes, while gapped Weyl systems are often expected to lose such distinctive responses. Here we show…

A field theory approach to Breit-type Hamiltonians in gapped Dirac systems
Xinhong Zhou, T. H. Hansson, Varsha Subramanyan +1
We develop a path-integral-based field theory for deriving Breit-type low-energy Hamiltonians for gapped Dirac systems coupled to both vector and axial gauge fields. Treating the m…
