[HTML][HTML] Statistical model of a superfluid solid
VI Yukalov, EP Yukalova - Physics Letters A, 2023 - Elsevier
A microscopic statistical model of a quantum solid is developed, where inside a crystalline
lattice there can exist regions of disorder, such as dislocation networks or grain boundaries.
The cores of these regions of disorder are allowed for exhibiting fluid-like properties. If the
solid is composed of Bose atoms, then the fluid-like aggregations inside the regions of
disorder can exhibit Bose-Einstein condensation and hence superfluidity. The regions of
disorder are randomly distributed throughout the sample, so that for describing the overall …
