Critical currents and melting temperature of a two-dimensional vortex lattice with periodic pinning
(2013-06-01)
The critical current and melting temperature of a vortex system are analyzed. Calculations are made for a two-dimensional film at finite temperature with two kinds of periodic pinning: hexagonal and Kagomé. A transport ...
Langevin simulation of scalar fields: Additive and multiplicative noises and lattice renormalization
(Elsevier B.V., 2012-08-15)
We consider the Langevin lattice dynamics for a spontaneously broken 44 scalar field theory where both additive and multiplicative noise terms are incorporated. The lattice renormalization for the corresponding stochastic ...
Ashcroft model potential study of lattice dynamics of alpha-iron and barium

Ashcroft model potential study of lattice dynamics of α-Iron and barium
(1999-01-01)
Ashcroft model potential has been used to compute phonon dispersion relations along the three principal symmetry directions, i.e. [k00], [kk0] and [kkk] for α-iron and barium. The computed phonons gave a reasonable agreement ...
Analysis of Lattice Size, Energy Density and Denaturation for a One-Dimensional DNA Model
(2012)
There are several mechanical models to describe the DNA phenomenology. In this work the DNA denaturation is stu- died under thermodynamical and dynamical point of view using the well known Peyrard-Bishop model. The ...
Vortex-lattice formation in a spin-orbit coupled rotating spin-1 condensate
(2020-11-06)
We study the vortex-lattice formation in a rotating Rashba spin-orbit (SO) coupled quasi-two-dimensional (quasi-2D) hyper-fine spin-1 spinor Bose-Einstein condensate (BEC) in the x-y plane using a numerical solution of the ...
Electron–lattice coupling after high-energy deposition in aluminum
(Elsevier, 2015-07)
This paper presents an analysis of the parameters of highly-excited electron subsystem of aluminum, appearing e.g. after swift heavy ion impact or laser pulse irradiation. For elevated electron temperatures, the electron ...
Molecular Dynamics simulations of track formation at different ensembles
(2013-01-01)
A series of Molecular Dynamics simulations of thermal spikes has been run in zircon. For two different ensembles: microcanonical one and a combination of microcanonical one acting on the simulation core with Langevin one ...
Avalanchelike magnetic relaxation in the peak-effect regime of a Nb-O solid solution
(American Physical SocCollege PkEUA, 1998)
Nonequilibrium dynamics of quantum fields
(Elsevier B.V., 2007-02-01)
The nonequilibrium effective equation of motion for a scalar background field in a thermal bath is studied numerically. This equation emerges from a microscopic quantum field theory derivation and it is suitable to a ...
