Abstract Silicon nitride (Si3N4) ceramics are used in numerous applications because of their
superior mechanical properties,. Their intrinsically brittle nature is a critical issue, but can be …

Understanding how complex systems respond to change is of fundamental importance in
the natural sciences. There is particular interest in systems whose classical newtonian …

Quantum dots provide a natural system in which to study both quantum and classical
features of transport. As a closed testbed, they provide a natural system with a very rich set …

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 …

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 …

Non-Kolmogorov-Arnold-Moser (KAM) systems, when perturbed by weak time-dependent
fields, offer a fast route to classical chaos through an abrupt breaking of invariant phase …

The manner in which unpredictable chaotic dynamics manifests itself in quantum mechanics
is a key question in the field of quantum chaos. Indeed, very distinct quantum features can …

We theoretically analyze the influence of magnetic field on small-signal absorption and gain
in a superlattice. We predict a very large and tunable THz gain due to nonlinear cyclotron …

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

We investigate the quantum-classical correspondence for a particle tunnelling through a
periodic superlattice structure with an applied bias voltage and an additional tilted harmonic …
