Revealing universal behaviours is a hallmark of statistical physics. Phenomena such as the
stochastic growth of crystalline surfaces and of interfaces in bacterial colonies, and spin …

Universality is a powerful concept, which enables making qualitative and quantitative
predictions in systems with extensively many degrees of freedom. It finds realizations in …

Bosonic condensates of exciton polaritons (light-matter quasiparticles in a semiconductor)
provide a solid-state platform for studies of nonequilibrium quantum systems with a …

Comparing with pure photons, higher nonlinearity in polariton systems has been exploited in
various proof-of-principle demonstrations of efficient optical devices based on the parametric …

Exciton polariton condensation is a macroscopic quantum state that can be efficiently
controlled by an external field through a nonlinear interaction. In an annular potential …

Modulational instabilities play a key role in a wide range of nonlinear optical phenomena,
leading, eg, to the formation of spatial and temporal solitons, rogue waves, and chaotic …

The paper demonstrates the existence of modulational instability (MI) in nonlinear exciton-
polariton condensates (EPCs). A set of coupled two-dimensional (2D) driven-dissipative …

Superfluidity, first discovered in liquid 4He, is closely related to Bose–Einstein condensation
(BEC) phenomenon. However, even at zero temperature, a fraction of the quantum liquid is …

Quantized vortices are fundamental to the two-dimensional dynamics of superfluids, from
quantum turbulence to phase transitions. However, surface effects have prevented direct …

Non-linearity and finite signal propagation speeds are omnipresent in nature, technologies,
and real-world problems, where efficient ways of describing and predicting the effects of …
