Computer Simulation Studies in Condensed Matter Physics: An Introductionained in this volume is the result of presentations and discussion that took place during the 15th Annual Workshop at the Center for Simulational Physics. The texts of both longer, invited presentations as well as a number of contributed papers are included. The reader will find that the scope of si

Low-Temperature Metastability of Ising Models: Prefactors, Divergences, and Discontinuitiesare performed using Monte Carlo with Absorbing Markov Chain algorithms to simulate extremely long low-temperature lifetimes. The question being addressed is at what temperatures the mathematically rigorous low-temperature results become valid. It is shown that the answer depends partly on how close

Fine-Grid Simulations of Thermally Activated Switching in Nanoscale Magnetsagnets to rapid changes in the applied magnetic field. The simulation can resolve magnetization patterns within nanomagnets and uses the Fast Multipole method to calculate dipole-dipole interactions efficiently. The thermal fluctuations play an essential part in the reversal process whenever the app

Determining the Saddle Point in Micromagnetic Models of Magnetization Switchinginite-temperature micromagnetics. A projective-dynamics method is used to determine the magnetization at the saddle point as a function of temperature. This magnetization is found to decrease linearly as the temperature is raised

Nonequilibrium Relaxation Analysis of Frustrated , Models in Two Dimensionswo different transitions, the chiral transition and the Kosterlitz-Thouless one, have been discussed. Further, we calculate the NER functions of fluctuations for these models, and analyze the universality class of them

First Principles Calculations of the Magnetic Structure in FeMn/Co Bilayers magnetization in the ground state. We find that the magnetic configuration does not differ significantly from bulk Co in the Co, however it changes from a bulk 3Q configuration to a 1Q like antiferromagnetic configuration in Fe.Mn.. Additionally, the Fe.Mn. moments are found to be mostly perpendicu

From Frustrated Ising Models to Quantum Computing model. They show that this model, originally derived as effective model for the low-energy physics of frustrated Ising models, has the right properties to be used in a physical realization of topologically protected quantum bits. A topologically protected quantum bit has the advantage of being pass
