Metastable states in the J1-J2 Ising model
V. A. Abalmasov, B. E. Vugmeister
We study the J1-J2 Ising model on the square lattice using the random local field approximation (RLFA) and Monte Carlo (MC) simulations for various values of the ratio p = J2/|J1|…
Comment on: "Phenomenological model of Dynamic Nonlinear Response in Relaxor Ferroelectrics
B. E. Vugmeister, H. Rabitz
In a recent paper (A.E. Glazounov and A.K. Tagantsev, Phys.Rev. Lett. 85, 2192 (2000)) it has been proposed a phenomenological model of the dynamic non-linear response in relaxor f…
Coexistence of the Critical Slowing Down and Glassy Freezing in Relaxor Ferroelectrics
B. E. Vugmeister, H. Rabitz
We have developed a dynamical model for the dielectric response in relaxor ferroelectrics which explicitly takes into account the coexistence of the critical slowing down and glass…
Echo in Optical Lattices: Stimulated Revival of Breathing Oscillations
A. Bulatov, A. Kuklov, B. E. Vugmeister +1
We analyze a stimulated revival (echo) effect for the breathing modes of the atomic oscillations in optical lattices. The effect arises from the dephasing due to the weak anharmoni…
Dynamics of interacting clusters and dielectric response of relaxor ferroelectrics
B. E. Vugmeister, H. Rabitz
The dielectric response in relaxor ferroelectrics is analyzed in the framework a model for the polarization dynamics in the presence of polar clusters. We associate the origin of p…
Nonstationary Optimal Paths and Tails of Prehistory Probability Density in Multistable Stochastic Systems
B. E. Vugmeister, J. Botina, H. Rabitz
The tails of prehistory probability density in nonlinear multistable stochastic systems driven by white Gaussian noise, which has been a subject of recent study, are analyzed by em…
