Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

The thermal boundary resistance present at interfaces between helium and solids (Kapitza
resistance) and the thermal boundary resistance at interfaces between two solids are …

The distribution of magnetic moments in a ferromagnetic crystal is investigated. It is found
that such a crystal consists of elementary layers magnetized to saturation. The width of these …

This book is devoted to BEC as an interdisciplinary subject, covering atomic and molecular
physics, laser physics, low temperatures, and astrophysics, and it will serve as an in-depth …

This paper presents an attempt of explaining the phenomenon of superfluidity on the basis
of the theory of degeneracy of a non-perfect Bose-Einstein gas. By using the method of the …

One of Feynman's early applications of path integrals was to superfluid He 4. He showed
that the thermodynamic properties of Bose systems are exactly equivalent to those of a …

By combining theory and experiments, we demonstrate that dipolar quantum gases of both
Er 166 and Dy 164 support a state with supersolid properties, where a spontaneous density …

The concept of transmission of heat by waves is reviewed and interpreted. The notion of an
effective thermal conductivity, an effective heat capacity, and relaxation functions for heat …

The mathematical description of BE (Bose-Einstein) condensation is generalized so as to be
applicable to a system of interacting particles. BE condensation is said to be present …
