Title: Excitations in Correlated Superfluids near a Continuous Transition into a Supersolid

Abstract

We study a superfluid on a lattice close to a transition into a supersolid phase and show that a uniform superflow in the homogeneous superfluid can drive the roton gap to zero. This leads to supersolid order around the vortex core in the superfluid, with the size of the modulated pattern around the core being related to the bulk superfluid density and roton gap. We also study the electronic tunneling density of states for a uniform superconductor near a phase transition into a supersolid phase. Implications are considered for strongly correlated superconductors.

  • Measurements of the average thermal conductivity k/sub exp/ is identical to hQ/BETAT and of the thermal relaxation time GAMMA to reach steady-state equilibrium conditions are reported in the superfluid phase for dilute mixtures of /sup 3/He in /sup 4/He. Here h is the cell height, Q is the heat flux, and BETAT is the temperature difference across the fluid layer. The measurements were made over the impurity range 2 x 10/sup -9/ < x (/sup 3/He) < 3 x 10/sup -2/ and with heat fluxes 0.3 < q < 160 ..mu.. w/cm/sup 2/. Assuming the boundary resistance R /sub b/,more » measured for x < 10/sup -5/, to be independent of x over the whole range of x, a calculation is given for k/sub exp/. for Q smaller than a well-defined critical heat flux Q /sub c/ (X) proportional to X/sup 0.9/, k/sub exp/. for Q of Q and can be identified with the local conductivity K/sub eff/, which is found to be independent of the reduced temperature epsilon = (T - T/sub lambda/)/ T/sub lambda/ for -epsilon less than or equal to 10/sup -2/ from the prediction extrapolated value at T/sub lambda/ is found to depart for X less than or equal to 10/sup -3/ from the prediction k/sub lambda/ proportional to X/sup -1/, tending instead to a weaker divergence k/sub lambda/ proportional to X/sup -a/ with aapprox. = 0.8. A finite conductivity as X tends to zero is not excluded by the data, however. For Q > Q/sub c/ (X) a nonlinear regime is entered. for X less than or equal to 10/sup -6/, the measurements with the availavle temperature resolution are limited to the nonlinear conditions, but can be extrapolated into the linear regime for X greater than or equal to 2 x 10/sup -7/. the results for K /sub exp/ (Q), Q/sub c/ (X), and k /sub eff/ (XX) are found to be internally consistent, as shown by comparison with a theory by Behringer based on Khalatnikov's transport equations.« less
  • The specific heat of the {ital x}-{ital y} model is studied on cubic lattices of sizes {ital L}{times}{ital L}{times}{ital L} and on lattices {ital L}{times}{ital L}{times}{ital H} with {ital L}{much_gt}{ital H} (i.e., on lattices representing a film geometry) using the cluster Monte Carlo method. Periodic boundary conditions were applied in all directions. In the cubic case we obtained the ratio of the critical exponents {alpha}/{nu} from the size dependence of the energy density at the critical temperature {ital T}{sub {lambda}}. Using finite-size scaling theory, we find that while for both geometries our results scale to universal functions, these functions differmore » for the different geometries. We compare our findings to experimental results and results of renormalization-group calculations.« less
  • Transport and relaxation processes in an anisotropic superfluid close to the transition temperature are discussed by deriving the quasiparticle Boltzmann equation. As an application the shear viscosity of liquid /sup 3/He is calculated exactly to first order in the superfluid gap, in terms of normal state properties. Exact results for the transport coefficients and relaxation rates in the superfluid enable one to extract precise information about normal state scattering amplitudes from measurements in the superfluid phases.
  • We show that correlated hopping of triplets, which is often the dominant source of kinetic energy in dimer-based frustrated quantum magnets, produces a remarkably strong tendency to form supersolid phases in a magnetic field. These phases are characterized by simultaneous modulation and ordering of the longitudinal and transverse magnetization, respectively. Using quantum Monte Carlo and a semiclassical approach for an effective hard-core boson model with nearest-neighbor repulsion on a square lattice, we prove, in particular, that a supersolid phase can exist even if the repulsion is not strong enough to stabilize an insulating phase at half-filling. Experimental implications for frustratedmore » quantum antiferromagnets in a magnetic field at zero and finite temperature are discussed.« less
  • We study the behavior of a Bose-Einstein condensate in which atoms are weakly coupled to a highly excited Rydberg state. Since the latter have very strong van der Waals interactions, this coupling induces effective, nonlocal interactions between the dressed ground state atoms, which, opposed to dipolar interactions, are isotropically repulsive. Yet, one finds partial attraction in momentum space, giving rise to a roton-maxon excitation spectrum and a transition to a supersolid state in three-dimensional condensates. A detailed analysis of decoherence and loss mechanisms suggests that these phenomena are observable with current experimental capabilities.
