Collective dynamics from stochastic thermodynamics

open access: yesNew Journal of Physics, 2015
From a viewpoint of stochastic thermodynamics, we derive equations that describe the collective dynamics near the order-disorder transition in the globally coupled XY model and near the synchronization–desynchronization transition in the Kuramoto model ...

Controllable switching of vortex chirality in magnetic nanodisks by a field pulse

open access: yes, 2007
We propose a way of fast switching the chirality in a magnetic nanodisk by applying a field pulse. To break the symmetry with respect to clockwise or counterclockwise chirality a mask is added by which an inhomogeneous field influences the vortex state ...

Two dimensional kicked quantum Ising model: dynamical phase transitions

open access: yesNew Journal of Physics, 2014
Using an efficient one and two qubit gate simulator operating on graphical processing units, we investigate ergodic properties of a quantum Ising spin $1/2$ model on a two-dimensional lattice, which is periodically driven by a δ -pulsed transverse ...

Spatial confinement causes lifetime enhancement and expansion of vortex rings with positive filament tension

open access: yesNew Journal of Physics, 2015
We study the impact of spatial confinement on the dynamics of three-dimensional (3D) excitation vortices with circular filaments. In a chemically active medium we observe a decreased contraction rate of such scroll rings and even expanding ones, despite ...

MHD and Slip Effect on Two-immiscible Third Grade Fluid on Thin Film Flow over a Vertical Moving Belt

open access: yesOpen Physics, 2019
The present paper related to thin film flows of two immiscible third grade fluids past a vertical moving belt with slip conditions in the presence of uniform magnetic field.
