Role of Bose Statistics in Crystallization and Quantum Jamming
M. Boninsegni, L. Pollet, N. Prokof'ev +1
Indistinguishability of particles is a major factor destabilizing crystalline order in Bose systems. We describe this effect in terms of damped quasi-particle modes and in the dual…
Phase diagram of soft-core bosons in two dimensions
S. Saccani, S. Moroni, M. Boninsegni
The low temperature phase diagram of Bose soft disks in two dimensions is studied by numerical simulations. It is shown that a supersolid cluster phase exists, within a range of th…
Superfluidity of Grain Boundaries in Solid Helium-4
L. Pollet, M. Boninsegni, A. B. Kuklov +3
By large-scale quantum Monte Carlo simulations we show that grain boundaries in Helium-4 crystals are generically superfluid at low temperature, with a transition temperature of th…
Anisotropic Condensation of Helium in Nanotube Bundles
M. W. Cole, V. H. Crespi, G. Stan +3
Helium atoms are strongly attracted to the interstitial channels within a bundle of carbon nanotubes. The strong corrugation of the axial potential within a channel can produce a l…
