The Kardar-Parisi-Zhang (KPZ) universality class provides a unifying framework for understanding the evolution of fluctuating interfaces and non-equilibrium phenomena. Stochastic processes governed by ...

Abstract: The KPZ equation was introduced in the eighties as a model of surface growth, but it was soon realised that its solution is a much more "universal" object describing the crossover between ...

How it works: the wave in the foreground is an illustration of the phase of an out-of-equilibrium Bose-Einstein condensate in a 1D cavity, which belongs to the Kardar-Parisi-Zhang universality class.

In this work we focus on the two-dimensional anisotropic KPZ (aKPZ) equation, which is formally given by ∂ t h= v 2 Δh+λ( ( ∂ 1 h ) 2 − ( ∂ 2 h ) 2 )+ v 1 2 ξ , where ξ denotes a noise which is white ...

Our research focus here employs probabilistic and analytic methods to explore complex random systems. At its core, the methods developed and utilized include a wide array of tools from stochastic ...

The rapid progress of quantum simulators is now enabling them to study problems that before have been limited to the domain of theoretical physics and numerical simulation. A team of researchers at ...
