Superfluidity of dense 4He in vycor.
We calculate properties of a model of 4He in Vycor using the path integral Monte Carlo method. We find that 4He forms a distinct layered structure with a highly localized first layer, a disordered second layer with some atoms delocalized and able to give rise to the observed superfluid response, and higher layers of nearly perfect crystals. The addition of a single 3He atom was enough to bring ...
متن کاملTunable superfluidity and quantum magnetism with ultracold polar molecules.
By selecting two dressed rotational states of ultracold polar molecules in an optical lattice, we obtain a highly tunable generalization of the t-J model, which we refer to as the t-J-V-W model. In addition to XXZ spin exchange, the model features density-density interactions and density-spin interactions; all interactions are dipolar. We show that full control of all interaction parameters in ...
متن کاملA Continuum and Molecular Dynamics Simulation of Nano - droplets Collision
The extent to which the continuum treatment holds in binary droplet collisions is examined in the present work by using a continuum-based implicit surface capturing strategy (Volume-of-Fluid coupled to Navier-Stokes) and a molecular dynamics methodology. The droplet pairs are arranged in a head-on-collision configuration with an initial separation distance of 5.3 nm and a velocity of 3 ms. The ...
متن کاملMicroscopic approach to the response of 3He-4He mixtures.
Correlated-basis-function perturbation theory is used to evaluate the zero-temperature response S(q ,v) of He-He mixtures for inelastic neutron scattering, at momentum transfers q ranging from 1.1 to 1.8 Å. We adopt a Jastrow correlated ground state and a basis of correlated particle-hole and phonon states. We insert correlated one-particle–one-hole and oneand two-phonon states to compute the s...
متن کاملQuantum Evaporation from Superfluid 4He
The quantum evaporation experiments of Brown and Wyatt have been re-analysed in the light of a recent measurement of the high-energy phonon spectrum created by a pulse-heated thin film. Two sources of systematic error become significant at the level of the precision required by this new analysis: firstly, in the detector position which is recalibrated by using large-angle roton evaporation; and...
