Bose-Einstein condensation and gauge symmetry breaking
V. I. Yukalov
The fundamental problem is analized, the relation between Bose-Einstein condensation and spontaneous gauge symmetry breaking. This relation is largerly misunderstood in physics com…
Structure factor of Bose-condensed systems
V. I. Yukalov
The structure factor for a Bose system with Bose-Einstein condensate is considered in the frame of the self-consistent mean-field approximation. The accomplished analysis demonstra…
Endogenous versus Exogenous Origins of Diseases
D. Sornette, V. I. Yukalov, E. P. Yukalova +3
Many illnesses are associated with an alteration of the immune system homeostasis due to any combination of factors, including exogenous bacterial insult, endogenous breakdown (e.g…
Order parameter for the dynamical phase transition in Bose-Einstein condensates with topological modes
E. R. F. Ramos, L. Sanz, V. I. Yukalov +1
In a trapped Bose-Einstein condensate, subject to the action of an alternating external field, coherent topological modes can be resonantly excited. Depending on the amplitude of t…
Method of self-similar factor approximants
V. I. Yukalov, E. P. Yukalova
The method of self-similar factor approximants is completed by defining the approximants of odd orders, constructed from the power series with the largest term of an odd power. It…
Condensate and superfluid fractions for varying interactions and temperature
V. I. Yukalov, E. P. Yukalova
A system with Bose-Einstein condensate is considered in the frame of the self-consistent mean-field approximation, which is conserving, gapless, and applicable for arbitrary intera…
Calculation of critical exponents by self-similar factor approximants
V. I. Yukalov, E. P. Yukalova
The method of self-similar factor approximants is applied to calculating the critical exponents of the O(N)-symmetric phi^4 theory and of the Ising glass. It is demonstrated that t…
Ramsey fringes formation during excitation of topological modes in a Bose-Einstein condensate
E. R. F. Ramos, L. Sanz, V. I. Yukalov +1
The Ramsey fringes formation during the excitation of topological coherent modes of a Bose-Einstein condensate by an external modulating field is considered. The Ramsey fringes app…
Representative Ensembles in Statistical Mechanics
V. I. Yukalov
The notion of representative statistical ensembles, correctly representing statistical systems, is strictly formulated. This notion allows for a proper description of statistical s…
Bose-Einstein-condensed gases with arbitrary strong interactions
V. I. Yukalov, E. P. Yukalova
Bose-condensed gases are considered with an effective interaction strength varying in the whole range of the values between zero and infinity. The consideration is based on the usa…
Nonlinear Dynamical Model of Regime Switching Between Conventions and Business Cycles
V. I. Yukalov, D. Sornette, E. P. Yukalova
We introduce and study a non-equilibrium continuous-time dynamical model of the price of a single asset traded by a population of heterogeneous interacting agents in the presence o…
