Crystalline axion electrodynamics in charge-ordered Dirac semimetals
Julian May-Mann, Mark R. Hirsbrunner, Lei Gioia +1
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…

Topological order in interacting semimetals
Jinmin Yi, Xuzhe Ying, Lei Gioia +1
It has recently been demonstrated that it is possible to open a gap in a magnetic Weyl semimetal, while preserving the chiral anomaly along with the charge conservation and transla…

Unquantized anomalies in topological semimetals
Lei Gioia, Chong Wang, A. A. Burkov
Topological semimetals are a new class of metallic materials, which exist at band fillings that ordinarily correspond to insulators or compensated accidental semimetals with zero L…
