WebApr 12, 2024 · Periodically driven (Floquet) systems are described by time dependent Hamiltonians that possess discrete time translation symmetry. The spontaneous breaking of this symmetry leads to the... WebModeling time crystals Single particle systems In the s: 1 resonance case: • There are s Floquet eigenstates with quasi-energies E j≈ E ′. These quasi-energies form a band when s → ∞. • s individual wavepackets, ϕj(z,t), can be prepared by superposing s Floquet eigenstates. For s → ∞, the wavepackets ϕj(z,t) become analogues of Wannier states but in the time …
