Recent studies on exceptional points (EPs) in non-Hermitian optical systems have revealed
unique traits, including unidirectional invisibility, chiral mode switching and laser self …

We investigate experimentally and theoretically a system ruled by an intricate interplay
between topology, nonlinearity, and spontaneous symmetry breaking. The experiment is …

Exceptional points (EPs)—spectral singularities of non-Hermitian linear systems—have
recently attracted interest for sensing. While initial proposals and experiments focused on …

Symmetry and symmetry breaking of light states play an important role in photonic integrated
circuits and have recently attracted lots of research interest that is relevant to the …

Cavity exciton polariton physics and cavity optomechanics have evolved into mature and
active domains with, so far, very little connections between them. We argue here that there …

Spontaneous symmetry breaking (SSB) plays a central role in understanding a large variety
of phenomena associated with phase transitions, such as superfluid and superconductivity …

The nonequilibrium dynamics of light in a coherently driven nonlinear cavity resembles the
equilibrium dynamics of a Brownian particle in a scalar potential. This resemblance has …

Spontaneous symmetry breaking (SSB) is key for our understanding of phase transitions
and the spontaneous emergence of order. In this work, we report that, for a two-dimensional …

We demonstrate theoretically and experimentally that linear coupling due to the
backscattering between two counterpropagating modes in a Kerr microresonator leads to …

We demonstrate an all-optical random number generator based on spontaneous symmetry
breaking in a coherently driven Kerr resonator. Random bit sequences are generated by …
