Subdiffusion in wave packets with periodically kicked interactions

Rayleigh-Jeans prethermalization and wave condensation in a nonlinear disordered Floquet system

“…in a one-dimensional lattice where both the onsite disordered potential and nonlinear interaction terms are periodically kicked [99][100][101][102][103][104]. Note that we could equally well kick the hopping amplitudes, the first term of the righthand side of eq.…”

Superfluidity vs. prethermalisation in a nonlinear Floquet system

“…-Driven systems with periodically kicked onsite potentials have attracted extensive attention to study the dynamical localization transition and engineer exotic topological phases of matter [38][39][40][41]. There has also been a rising interest with temporally modulated interactions to design synthetic gauge fields or modify the transport properties [42][43][44][45][46]. In the same spirit, we consider here bosonic particles hopping in a one-dimensional lattice (with unit lattice constant a = 1) comprising N sites (with periodic boundary conditions) where both the onsite potential and the mean-field (repulsive) interaction terms are periodically kicked with the same time sequence (time period T = 1 set to unity, driving frequency Ω = 2π).…”
