Exact multistability and dissipative time crystals in interacting fermionic lattices

Multistability is the possibility of a dissipative quantum many-body system to have multiple steady states - it is intensely studied, but its existence remains controversial. The paper settles this by providing an exactly provable case, and also proves that boundary time crystals can exist in intera...

description Multistability is the possibility of a dissipative quantum many-body system to have multiple steady states - it is intensely studied, but its existence remains controversial. The paper settles this by providing an exactly provable case, and also proves that boundary time crystals can exist in interacting lattice models, which was not known before.
