Theoretical physics deals with physical models. The main requirements for a good physical
model are simplicity and universality. Universal models which can be applied to describe a …

We report on the first model of a thermal transistor to control heat flow. Like its electronic
counterpart, our thermal transistor is a three-terminal device with the important feature that …

We investigated the driven dynamics of vortices confined to mesoscopic flow channels by
means of a dc-rf interference technique. The observed mode-locking steps in the IV curves …

We introduce a type of vortex entry edge barrier which controls the critical current in a
perpendicular magnetic field in thin-film weak-pinning superconducting strips …

Low-angle grain boundaries (GBs) in superconductors exhibit intermediate Abrikosov
vortices with Josephson cores, whose length l along GB is smaller than the London …

We examine vortex pinning and dynamics in thin-film superconductors containing
logarithmically interacting Pearl vortices moving through square and rectangular pinning …

Static and dynamic properties of superconducting vortices in a superconducting stripe with a
periodic array of weakly-superconducting (or normal metal) regions are studied in the …

We study the single file diffusion of a cyclic chain of particles that cannot cross each other, in
a thermal bath, with long-ranged interactions and arbitrary damping. We present simulations …

We discuss the twist map, with a special interest in its use for the finite Frenkel–Kontorova
model. We explain the meaning of the tensile force in some proposed models. We …

An overview is given of the new theories and experiments on the phase diagram of type II
superconductors, which in recent years have progressed from the Abrikosov mean field …
