Superfluid clusters, percolation and phase transitions in the disordered, two-dimensional Bose–Hubbard model
The Bose glass (BG) phase is the Griffiths region of the disordered Bose–Hubbard model (BHM), characterized by finite, quasi-superfluid clusters within a Mott insulating background. We propose to utilize this characterization to identify the complete zero-temperature phase diagram of the disordered BHM in d > 2 dimensions by analysing the geometric properties of what we call superfluid (SF) clu...
متن کاملEnergy and symmetry of self-assembled two-dimensional dipole clusters in magnetic confinement.
We report on confined two-dimensional (2D) dipole clusters formed by small ferromagnetic particles floating at the liquid-air interface and confined by nonuniform external magnetic field. The particles self assemble into hexagonally ordered clusters whose lattice constant can be magnetically tuned. We study the area S, the energy E, the chemical potential mu and the lattice constant a, of 2D cl...
متن کاملEXCITATIONS OF SUPERFLUID He IN CONFINEMENT
Neutron inelastic scattering studies of the elementary excitations in con ned super uid He are reviewed. Both recent work on helium in porous silica glass (aerogel, Vycor, etc.) and earlier work on helium lms on graphite surfaces are discussed. The global picture emerging from these studies is that the three-dimensional excitations are essentially the same as in bulk helium. The characteristic ...
متن کاملElasto-Thermodiffusive Response in a Two-Dimensional Transversely Isotropic Medium
The present article investigates the elasto-thermodiffusive interactions in a transversely isotropic elastic medium in the context of thermoelasticity with one relaxation time parameter and two relation time parameters. The resulting non-dimensional coupled equations are applied to a specific problem of a half-space in which the surface is free of tractions and is subjected to time-dependent th...
متن کاملQuasi two-dimensional superfluid Fermi gases
We study a quasi two-dimensional superfluid Fermi gas where the confinement in the third direction is due to a strong harmonic trapping. We investigate the behavior of such a system when the chemical potential is varied and find strong modifications of the superfluid properties due to the discrete harmonic oscillator states. We show that such quasi two-dimensional behavior can be created and ob...
