Title: Critical properties and Bose-Einstein condensation in dimer spin systems

Abstract

We analyze the spin relaxation time 1/T{sub 1} for a system made of weakly coupled one-dimensional ladders. This system allows us to probe the dimensional crossover between a Luttinger liquid and a Bose-Einstein condensate of magnons. We obtain the temperature dependence of 1/T{sub 1} in the various dimensional regimes, and discuss the experimental consequences.

  • We report new magnetization measurements on the spin-gap compound NiCl{sub 2}-4SC(NH{sub 2}){sub 2} at the low-field boundary of the magnetic field induced ordering. The critical density of the magnetization is analyzed in terms of a Bose-Einstein condensation (BEC) of bosonic quasiparticles. The analysis of the magnetization at the transition leads to the conclusion for the preservation of the U(1) symmetry, as required for BEC. The experimental data are well described by quantum Monte Carlo simulations.
  • We use the renormalization-group method to study the magnetic field influence on the Bose-Einstein condensation of interacting dilute magnons in three-dimensional spin systems. We first considered a model with SU(2) symmetry (universality class z=1) and we obtain for the critical magnetic field a power law dependence on the critical temperature, [H{sub c}(T)-H{sub c}(0)]{approx}T{sup 2}. In the case of U(1) symmetry (universality class z=2) the dependence is different, and the magnetic critical field depends linearly on the critical temperature, [H{sub c}(T)-H{sub c}(0)]{approx}T. By considering a more relevant model, which includes also the system's anisotropy, we obtain for the same symmetry classmore » a T{sup 3/2} dependence of the magnetic critical field on the critical temperature. We discuss these theoretical predictions of the renormalization group in connection with experimental results reported in the literature.« less
  • Recently it has been predicted that if a gas of spin-1/2 bosonic atoms is cooled down while conserving its total spin, it can form a Bose-Einstein condensate in a new type of fragmented state. In that fragmented state two orbital wave functions are macroscopically occupied. We derive a set of Gross-Pitaevskii equations that describe the two occupied wave functions, taking into account the effects of interatomic interactions. We then analyze the solutions of those equations in some special cases. In particular, we find that if the fragmented state is realized in a toroidal trap, under certain conditions the system willmore » spontaneously acquire macroscopic orbital angular momentum. Finally, we discuss the nature of the phase transition from an uncondensed gas to a fragmented-state condensate.« less
  • We determine the critical temperature of a 3D homogeneous system of hard-sphere bosons by path-integral Monte Carlo simulations and finite-size scaling. In the low density limit, we find that the critical temperature is increased by the repulsive interactions, as {Delta}T{sub C}/T{sub 0}{approximately}(na{sup 3} ){sup {gamma}} , where {gamma}=0.34{plus_minus}0.03 . At high densities the result for liquid helium, namely, a lower critical temperature than in the noninteracting case, is recovered. We give a microscopic explanation for the observed behavior. {copyright} {ital 1997} {ital The American Physical Society}
