Fast Vortex Core Switching at Moderate Temperatures

Ferromagnetic vortex core switching is investigated using micromagnetic simulations. For that the OOMMF program is used together with a temperature extension we have developed recently. This is a continuum micromagnetic approach, where the well-known Landau Lifshitz Gilbert equation (valid for zero temperature) is replaced by the Landau Lifshitz Bloch equation. In our research we simulate switc...

Dynamics of trapped Bose gases at finite temperatures

Starting from an approximate microscopic model of a trapped Bose-condensed gas at finite temperatures, we derive an equation of motion for the condensate wavefunction and a quantum kinetic equation for the distribution function for the excited atoms. The kinetic equation is a generalization of our earlier work in that collisions between the condensate and non-condensate (C 12) are now included,...

Dynamical Simulations of Trapped Bose Gases at Finite Temperatures

In this paper, we develop a numerical procedure for investigating the dynamics of trapped Bose gases based on the ZGN theory. The dynamical equations used consist of a generalized Gross-Pitaevskii equation for the con-densate order parameter and a semiclassical kinetic equation for the thermal cloud. The former is solved using a fast Fourier transform split-operator technique while the Boltzman...

Compression of Gases at Moderate and High Densities

The cell method developed by Lennard-Janes and Devonshire is applied by using a two-potential model for the configurational energy to the determination of the equation of state of argon, nitrogen, and methane up to nearly half the liquid densities D1 the temperature range from 0 to l50°C. The LennardJones6-l2 potential and the Kihara hard core model with parameters determined from the second vi...

Flexible Microreactor System for Chemical Research at Moderate Temperatures

Miniaturization is fast gaining attention in chemical processes that are conventionally carried out on a lab-scale or larger. Major progress and landmarks has been made during the last five years. A microreactor system has been developed for fast catalyst development and process optimization. This paper focuses on the issues of microreactor system design and characterization for fast and accura...
