A century of the Bose-Einstein condensation concept and half a century of the JINR experiments for observation of condensate in the superfluid 4He (He II)
Valentin Zagrebnov
This short review is devoted to celebration of two major events in quantum physics. The first one is the birth of the concept of Bose-Einstein condensation (1925) and the second is…
Non-conventional Dynamical Bose Condensation
Valentin A. Zagrebnov
The paper presents a review of results concerning the non-conventional dynamical condensation versus conventional Bose-Einstein condensation, including the case of generalised van…
Construction of dynamical semigroups by a functional regularisation à la Kato
A. F. M. ter Elst, Valentin A. Zagrebnov
A functional version of the Kato one-parametric regularisation for the construction of a dynamical semigroup generator of a relative bound one perturbation is introduced. It does n…
Disordered Bose Einstein Condensates with Interaction
Robert Seiringer, Jakob Yngvason, Valentin A. Zagrebnov
We study the effects of random scatterers on the ground state of the one-dimensional Lieb-Liniger model of interacting bosons on the unit interval in the Gross-Pitaevskii regime. W…
Disordered Bose Einstein Condensates with Interaction in One Dimension
R. Seiringer, J. Yngvason, V. A. Zagrebnov
We study the effects of random scatterers on the ground state of the one-dimensional Lieb-Liniger model of interacting bosons on the unit interval in the Gross-Pitaevskii regime. W…
Large Deviation Principle for Non-Interacting Boson Random Point Processes
Hiroshi Tamura, Valentin Zagrebnov
Limit theorems, including the large deviation principle, are established for random point processes (fields), which describe the position distributions of the perfect boson gas in…
