Crystalline axion electrodynamics in charge-ordered Dirac semimetals
Three-dimensional Dirac semimetals can be driven into an insulating state by coupling to a
charge density wave (CDW) order. Here, we consider the quantized crystalline responses of …

Gapless fermionic systems as phase-space topological insulators: Nonperturbative results from anomalies
We present a theory unifying the topological responses and anomalies of various gapless
fermion systems exhibiting Fermi surfaces, including those with Berry phases, and nodal …
