Nanomechanics has brought mesoscopic physics into the world of vibrations. Because
nanomechanical systems are small, fluctuations are significant, the vibrations already …

Time crystals are time-periodic self-organized structures postulated by Frank Wilczek in
2012. While the original concept was strongly criticized, it stimulated at the same time an …

In the presence of a circularly polarized mid-infrared radiation graphene develops
dynamical band gaps in its quasienergy band structure and becomes a Floquet insulator …

Quantum tunneling is the phenomenon that makes superconducting circuits “quantum”.
Recently, there has been a renewed interest in using quantum tunneling in phase space of a …

Time crystals are a phase of matter, for which the discrete time symmetry of the driving
Hamiltonian is spontaneously broken. The breaking of discrete time symmetry has been …

We study an array of coupled optical cavities in the presence of two-photon driving and
dissipation. The system displays a critical behavior similar to that of a quantum Ising model …

We present a new approach for deriving exact closed-form solutions for the steady state of a
wide class of driven-dissipative nonlinear resonators that is distinct from more common …

Time crystals are physical systems whose time translation symmetry is spontaneously
broken. Although the spontaneous breaking of continuous time-translation symmetry in static …

Time crystals are quantum many-body systems which are able to self-organize their motion
in a periodic way in time. Discrete time crystals have been experimentally demonstrated in …

Autonomous quantum error correction has gained considerable attention to avoid
complicated measurements and feedback. Despite its simplicity compared with the …
