Renormalization Effects in a Dilute Bose Gas
The low-density expansion for a homogeneous interacting Bose gas at zero temperature can be formulated as an expansion in powers of √ ρa, where ρ is the number density and a is the S-wave scattering length. Logarithms of ρa appear in the coefficients of the expansion. We show that these logarithms are determined by the renormalization properties of the effective field theory that describes the ...
متن کاملIndividual Tracer Atoms in an Ultracold Dilute Gas.
We report on the experimental investigation of individual Cs atoms impinging on a dilute cloud of ultracold Rb atoms with variable density. We study the relaxation of the initial nonthermal state and detect the effect of single collisions which has so far eluded observation. We show that, after few collisions, the measured spatial distribution of the tracer atoms is correctly described by a Lan...
متن کاملQuantum phase transitions beyond the dilute Bose gas limit
We study a Heisenberg S=1/2 ring-exchange antiferromagnet which exhibits a quantum phase transition from a spontaneously dimerized (valence bond solid) phase to a magnetically ordered (Néel) phase. We argue that the quantum transition is of unconventional nature; both singlet and triplet modes of high density condense as the transition is approached from the dimer side, signaling restoration of...
متن کاملCollisions and expansion of an ultracold dilute Fermi gas
– We discuss the effects of collisions on the expansion of a degenerate normal Fermi gas, following the sudden removal of the confining trap. Using a Boltzmann equation approach, we calculate the time dependence of the aspect ratio and the entropy increase of the expanding atomic cloud taking into account the collisional effects due to the deformation of the distribution function in momentum sp...
متن کاملFast thermalization and Helmholtz oscillations of an ultracold Bose gas.
We analyze theoretically the transport properties of a weakly interacting ultracold Bose gas enclosed in two reservoirs connected by a constriction. We assume that the transport of the superfluid part is hydrodynamic, and we describe the ballistic transport of the normal part using the Landauer-Büttiker formalism. Modeling the coupled evolution of the phase, atom number, and temperature mismatc...
