Properties of heavy rare-gases adlayers on graphene substrates
Lucas Madeira, Silvio A. Vitiello
We investigated properties of heavy rare-gases, Ne, Ar, Kr, Xe and Rn, adsorbed on graphene substrates using molecular dynamics. We gathered evidences of commensurate solids for Ne…
Vortex line in the unitary Fermi gas
Lucas Madeira, Silvio A. Vitiello, Stefano Gandolfi +1
We report diffusion Monte Carlo results for the ground state of unpolarized spin-1/2 fermions in a cylindrical container and properties of the system with a vortex-line excitation.…
Contact interaction in an unitary ultracold Fermi gas
Renato Pessoa, S. Gandolfi, S. A. Vitiello +1
An ultracold Fermi atomic gas at unitarity presents universal properties that in the diluted limit can be well described by a contact interaction. By employing a guide function wit…
Kinetic energies of liquid and solid phases of He
E. J. Rugeles, Sebastian Ujevic, S. A. Vitiello
Kinetic energies of a system of He are investigated at zero temperature. The multi-weight extension to the diffusion Monte Carlo method is used to implement the Feynman-Hellman…
