    • Temperature dependence of the vacancy formation energy in solid 4He 

      Rota, Riccardo; Boronat Medico, Jordi (Multidisciplinary Digital Publishing Institute (MDPI), 2018-09-01)
      Open Access
      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 ...
