Transition Temperature of Dilute, Weakly Repulsive Bose Gas
Masudul Haque, Andrei E. Ruckenstein
Within a quasiparticle framework, we reconsider the issue of computing the Bose-Einstein condensation temperature () in a weakly non-ideal Bose gas. The main result of this an…
Transverse Spin Diffusion in a Dilute Spin-Polarized Degenerate Fermi Gas
Denis I. Golosov, Andrei E. Ruckenstein
We re-examine the calculation of the transverse spin-diffusion coefficient in a dilute degenerate spin-polarized Fermi gas, for the case of s-wave scattering. The special feature o…
Charge and Spin Gap Formation in Exactly Solvable Hubbard Chains with Long-Rang Hopping
F. Gebhard, A. Girndt, A. E. Ruckenstein
We discuss the transition from a metal to charge or spin insulating phases characterized by the opening of a gap in the charge or spin excitation spectra, respectively. These trans…
Spin-Flavor Separation and Non-Fermi Liquid Behavior in the Multichannel Kondo Problem: A Large N Approach
Daniel L. Cox, Andrei E. Ruckenstein
We consider a generalization of the multichannel single-impurity Kondo model which we solve analytically in the limit , $M\rightarrow\infty…
