A light-induced Weyl semiconductor-to-metal transition mediated by Peierls instability

H. Ning, O. Mehio, C. Lian +7

Elemental tellurium is a strongly spin-orbit coupled Peierls-distorted semiconductor whose band structure features topologically protected Weyl nodes. Using time-dependent density…

Decoupling of static and dynamic criticality in a driven Mott insulator

A. de la Torre, K. L. Seyler, M. Buchhold +12

Dynamically driven interacting quantum many-body systems have the potential to exhibit properties that defy the laws of equilibrium statistical mechanics. A widely studied model is…
