Exploring self-consistency of the equations of axion electrodynamics in Weyl semimetals
Kuangyin Deng, John S. Van Dyke, Djordje Minic +2
Recent works have provided evidence that an axial anomaly can arise in Weyl semimetals. If this is the case, then the electromagnetic response of Weyl semimetals should be governed…

Discrete time crystal in the gradient field Heisenberg model
Bikun Li, John S. Van Dyke, Ada Warren +2
We show that time crystal phases, which are known to exist for disorder-based many-body localized systems, also appear in systems where localization is due to strong magnetic field…

Field-induced Ferrohastatic Order in Cubic Non-Kramers Doublet Systems
John S. Van Dyke, Guanghua Zhang, Rebecca Flint
Cubic Pr-based compounds with non-Kramers doublet ground states can realize a novel heavy Fermi liquid with spinorial hybridization ('hastatic' order) that breaks time revers…
