Noise-induced switching between coexisting metastable states occurs in a wide range of far-from-equilibrium systems including micro-mechanical oscillators, epidemiological and climate change models, and nonlinear electronic transport in tunneling str

Understanding the spatiotemporal structure of most probable fluctuation pathways to rarely occurring states is a central problem in the study of noise-driven, nonequilibrium dynamical systems. When the underlying system does not possess detailed bala

Static domain formation in doped, weakly coupled semiconductor superlattices results in several current branches separated by discontinuities that exhibit hysteresis. The transition from one branch to its adjacent higher and lower one is studied by t

We demonstrate the possibility to systematically steer the most probable escape paths (MPEPs) by adjusting relative noise intensities in dynamical systems that exhibit noise-induced escape from a metastable point via a saddle point. With the use of a

GaAs/AlAs single quantum well structures designed with well thickness near the type-I/type-II crossover show distinctive photoluminescence peaks corresponding to both type-I and type-II recombinations. Photoluminescence measurements as a function of

Phonon‐assisted tunneling (PAT) has been studied in detail for two similar GaAs/AlAs double‐barrier structures. Calculations of the PAT current—including effects of optical‐phonon localization—are in good agreement with experimental data, a

We report on measurements of first-passage-time distributions associated with current switching in weakly coupled $\mathrm{GaAs}/\mathrm{AlAs}$ superlattices driven by shot noise, a system that is both far from equilibrium and high dimensional. Stati
