Physical systems exhibiting fast spontaneous chaotic oscillations are used to generate high-quality true random sequences in random number generators. The concept of using fast practical entropy sources to produce true random sequences is crucial to make storage and transfer of data more secure at very high speeds. While the first high-speed devices were chaotic semiconductor lasers, the discovery of spontaneous chaos in semiconductor superlattices at room temperature provides a valuable…

Designing Hyperchaos and Intermittency in Semiconductor Superlattices.
TLDR
This system exhibits hyperchaos and varieties of intermittent chaos in extended dc voltage ranges and its chaotic attractors are robust and resilient against noises and against controlled random disorder due to growth fluctuations.
Chaos-based true random number generators
TLDR
A mathematical model is explained to describe spontaneous chaos in semiconductor superlattices at room temperature, solved numerically to reveal the origin and characteristics of chaotic oscillations, and the limitations of the model are discussed in view of known experiments.

Intermittency route to chaos and broadband high-frequency generation in semiconductor superlattice coupled to external resonator.
TLDR
The analysis shows that the transition to chaos, which is confirmed by calculation of Lyapunov exponents, is associated with the intermittency scenario and the evolution of the laminar phases and the corresponding Poincare maps with variation of a supercriticality parameter suggest that the observed dynamics can be classified as type I intermittency.
Nonlinear Quantum Mechanics
We show that the nonlinear bifurcations found by simulations in single quantum wells in the terahertz regime [5, 6, 25] also occur in semiconductor superlattices (SSLs) in the gigahertz range [2, 3,

TLDR
This analysis shows that the chaotic dynamical phases exist on a number of sub-manifolds of codimension zero within the design parameter space of short (5-25 period), n-doped, Ga/(Al,Ga)As semiconductor superlattices (SSLs) in the sequential resonant tunneling regime.

Coherence Resonance and Stochastic Resonance in an Excitable Semiconductor Superlattice.
TLDR
The device-dependent critical current for the coherence resonance is determined from experiments and numerical simulations and it is described through numerical simulations how a coherence Resonance triggers a stochastic resonance when its oscillation mode becomes locked to a weak ac external voltage signal.
