Evolution of Concentration Under Lattice Spin-Flip Dynamics

Evolution of entanglement for spin-flip dynamics

A model of evolution of entanglement of bipartite quantum state is studied. It involves recently introduced quantum block spin-flip dynamics and the concept of formation of entanglement. For initially separable states the considered evolution leads to entangled states. We observe and discuss general two-points correlation function for that type of dynamics.

Projected single-spin-flip dynamics in the Ising model.

We study transition matrices for projected dynamics in the energy-magnetization, magnetization, and energy spaces. Several single-spin-flip dynamics are considered, such as the Glauber and Metropolis canonical ensemble dynamics, and the Metropolis dynamics for three multicanonical ensembles: the flat energy-magnetization, the flat energy, and the flat magnetization histograms. From the numerica...

Current-Controlled Magnetization Dynamics in the Spin-Flip Transistor

Parallel algorithm for spin and spin-lattice dynamics simulations.

To control numerical errors accumulated over tens of millions of time steps during the integration of a set of highly coupled equations of motion is not a trivial task. In this paper, we propose a parallel algorithm for spin dynamics and the newly developed spin-lattice dynamics simulation [P. W. Ma, Phys. Rev. B 78, 024434 (2008)]. The algorithm is successfully tested in both types of dynamic ...

Single - Atom Spin - Flip Spectroscopy

There is still some dispute over whether the relationship is entirely consistent with Bayesian updating (37). 14. R. M. Dawes, J. Exp. Soc. Psychol. 25, 1 (1989). 15. D. Fudenberg, J. Tirole, Game Theory (MIT Press, Cambridge, MA, 2000). 16. With finite players, the truth-telling result holds provided that the number of players exceeds some finite n, which in turn depends on p(<). 17. J. M. Ber...
