Resonant Bose Condensate: Analog of Resonant Atom
V. I. Yukalov, E. P. Yukalova, V. S. Bagnato
The resonant formation of nonlinear coherent modes in trapped Bose-Einstein condensates is studied. These modes represent nonground-state Bose condensates. The methods of describin…
Irreversibility of Time for Quasi-Isolated Systems
V. I. Yukalov
A physical system is called quasi-isolated if it subject to small random uncontrollable perturbations. Such a system is, in general, stochastically unstable. Moreover, its phase-sp…
Expansion Exponents for Nonequilibrium Systems
V. I. Yukalov
Local expansion exponents for nonequilibrium dynamical systems, described by partial differential equations, are introduced. These exponents show whether the system phase volume ex…
Self-Similar Extrapolation for the Law of Acoustic Emission Before Failure of Heterogeneous Materials
A. Moura, V. I. Yukalov
Acoustic emission before the failure of heterogeneous materials is studied as a function of applied hydrostatic pressure. A formula for the energy release is suggested, which is va…
Nuclear Spin Superradiance
V. I. Yukalov
The review of experimental and main theoretical works on the phenomenon of nuclear spin superradiance is given. The content includes: 1. Introduction, 2. Experimental Observation,…
Interplay between Quantum and Coherent Effects in Optics
V. I. Yukalov
A technique is presented for treating strongly nonstationary and transient processes in optics, permitting one to take into account both types of competing with each other effects,…
