Uniform electron gas in the presence of space-time periodic potentials: Floquet-Bloch and linear-response theory

Aps.org·September 24, 2026

Nonequilibrium quantum physics greatly simplifies in the case of time-periodic Hamiltonians, since Floquet theory provides an analog to Bloch's theorem in the time domain. Still, the formal properties of Floquet many-body theory remain underexplored. Here, we…
