We show that resonant electron transport in semiconductor superlattices with an applied
electric and tilted magnetic field can, surprisingly, become more pronounced as the lattice …

Semiconductor superlattices are strongly nonlinear media offering several technological
challenges associated with the generation of high-frequency Gigahertz radiation and very …

We show that a tilted magnetic field transforms the structure and THz dynamics of charge
domains in a biased semiconductor superlattice. At critical field values, strong coupling …

It has been known that noise can suppress multistability by dynamically connecting
coexisting attractors in the system which are otherwise in separate basins of attraction. The …

We propose a new type of optical transistor for a broadband amplification of terahertz
radiation. It is made of a graphene-superconductor hybrid, where electrons and Cooper …

We demonstrate, through experiment and theory, enhanced high-frequency current
oscillations due to magnetically-induced conduction resonances in superlattices. Strong …

Achieving Bloch oscillations of free carriers under a direct current, a long-sought-after
collective many-body behavior, has been challenging due to stringent constraints on the …

We discuss a numerical method for the calculation of the spectrum of Lyapunov exponents
for spatially extended systems described by coupled Poisson and continuity equations. This …

Historically, semiconductor superlattices, artificial periodic structures of different
semiconductor materials, were invented with the purpose of engineering or manipulating the …

We theoretically study the high-frequency response of charge domains traveling through a
strongly coupled semiconductor superlattice with an applied harmonic electromagnetic …
