Time Crystal from Self-Amplification of Spontaneous Analog Hawking Radiation
Juan Ramón Muñoz de Nova, Fernando Sols
We propose a time crystal based on a quantum black-hole laser, where the genuinely spontaneous character of the symmetry breaking stems from the self-amplification of spontaneous H…

Simultaneous symmetry breaking in spontaneous Floquet states: temporal Floquet-Nambu-Goldstone modes, Floquet thermodynamics, and the time operator
Juan Ramón Muñoz de Nova, Fernando Sols
We study simultaneous symmetry breaking in spontaneous Floquet states, focusing on the specific case of an atomic condensate. We first describe the quantization of the Nambu-Goldst…
