A contribution of the electron-phonon scattering to the conductivity of a quantum cylinder in a magnetic field is calculated. It is demonstrated that the nanotube conductivity undergoes the Aharonov–Bohm oscillations with changes of the magnetic flux through the nanotube cross section.

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Svendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for two models in different universality classes: the Ising model and the Potts model with three components. The overlap of two ...

Two-dimensional systems with Rashba spin-orbit coupling are not Galilean invariant and therefore electron–
electron collisions in them may affect the current. However, when taken alone, they cannot ensure a nonzero
dc resistivity, so their effects are masked by impurity scattering. Here we calculate the related finite-frequency
response and show that the electron–electron scattering in clean Rashba conductors decreases ...
