Temperature Dependence of the Vacancy Formation Energy in Solid 4He
We studied the thermal effects on the behavior of incommensurate solid 4He at low temperatures using the path integral Monte Carlo method. Below a certain temperature, depending on the density and the structure of the crystal, the vacancies delocalize and a finite condensate fraction appears. W...
