Absence of off-diagonal long-range order in hcp He dislocation cores
Maurice de Koning, Wei Cai, Claudio Cazorla +1
The mass transport properties along dislocation cores in hcp He are revisited by considering two types of edge dislocations as well as a screw dislocation, using a fully correl…
The Limit of Mechanical Stability in Quantum Crystals: A Diffusion Monte Carlo Study of Solid 4He
Claudio Cazorla, Jordi Boronat
We present a first-principles study of the energy and elastic properties of solid helium at pressures below the range in which is energetically stable. We find that the limit of me…
Elastic Constants of Incommensurate Solid 4He
Claudio Cazorla, Yaroslav Lutsyshyn, Jordi Boronat
We study the elastic properties of incommensurate solid 4He in the limit of zero temperature. Specifically, we calculate the pressure dependence of the five elastic constants (C11,…
Two-dimensional molecular para-hydrogen and ortho-deuterium at zero temperature
C. Cazorla, J. Boronat
We study molecular para-hydrogen (p-) and ortho-deuterium (o-) in two dimensions and in the limit of zero temperature by means of the diffusion Monte Carl…
Bose-Einstein Quantum Statistics and the Ground State of Solid 4He
C. Cazorla, G. E. Astrakharchik, J. Casulleras +1
The ground state of solid He is studied using the diffusion Monte Carlo method and a new trial wave function able to describe the supersolid. The new wave function is symmetric…
Superfluidity versus localization in bulk 4He at zero temperature
C. Cazorla, J. Boronat
We present a zero-temperature quantum Monte Carlo calculation of liquid He immersed in an array of confining potentials. These external potentials are centered in the lattice s…
