A microscopic statistical model of a quantum solid is developed, where inside crystalline lattice there can exist regions disorder, such as dislocation networks or grain boundaries. The cores these disorder are allowed for exhibiting fluid-like properties. If the composed Bose atoms, then aggregations exhibit Bose-Einstein condensation and hence superfluidity. randomly distributed throughout sa...
