  • Squeezing in the weakly interacting uniform Bose-Einstein condensate 

    Haque, Masudul; Ruckenstein, Andrei E. (AMERICAN PHYSICAL SOC, 2006-10-01)
    We investigate the presence of squeezing in the weakly repulsive uniform Bose gas, in both the condensate mode and in the nonzero opposite-momenta mode pairs, using two different variational formulations. We explore the ...
  • Optimal path to epigenetic switching 

    Roma, D. M.; O'Flanagan, R. A.; Ruckenstein, A. E.; Sengupta, A. M.; Mukhopadhyay, R. (AMERICAN PHYSICAL SOC, 2005-01-01)
    We use large deviation methods to calculate rates of noise-induced transitions between states in multistable genetic networks. We analyze a synthetic biochemical circuit, the toggle switch, and compare the results to those ...
  • Transition temperature of dilute, weakly repulsive Bose gas 

    Haque, Masudul; Ruckenstein, Andrei E. (2002-12-25)
    Within a quasiparticle framework, we reconsider the issue of computing the Bose-Einstein condensation temperature (T_c) in a weakly non-ideal Bose gas. The main result of this and previous investigations is that T_c increases ...
  • Transverse spin diffusion in a dilute spin-polarized degenerate Fermi gas 

    Golosov, D. I.; Ruckenstein, A. E. (SPRINGER/PLENUM PUBLISHERS, 1998-08-01)
    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 of this limit is that the dependence of the ...
  • Charge-gap and spin-gap formation in exactly solvable Hubbard chains with long-range hopping 

    GEBHARD, F.; GIRNDT, A.; RUCKENSTEIN, A. E. (AMERICAN PHYSICAL SOC, 1994-04-15)
    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 transitions are addressed within the context ...
  • Quantum vertex model for reversible classical computing 

    Chamon, C.; Mucciolo, E. R.; Ruckenstein, A. E.; Yang, Z-C (NATURE PUBLISHING GROUP, 2017-05-12)
    Mappings of classical computation onto statistical mechanics models have led to remarkable successes in addressing some complex computational problems. However, such mappings display thermodynamic phase transitions that ...
  • Bose condensation without broken symmetries 

    Ruckenstein, A. E. (KLUWER ACADEMIC/PLENUM PUBL, 2000-12-01)
    This paper considers the issue of Bose–Einstein condensation in a weakly interacting Bose gas with a fixed total number of particles. We use an old current algebra formulation of non-relativistic many body systems due to ...
  • Band crossing and novel low-energy behaviour in a mean field theory of a three-band model on a Cu-O lattice 

    Golosov, D. I.; Ruckenstein, A. E.; Horbach, M. L. (IOP PUBLISHING LTD, 1998-04-20)
    We study correlation effects in a three-band extended Hubbard model of Cu - O planes within the 1/N mean field approach in the infinite U limit. We investigate the emerging phase diagram and discuss the low energy scales ...
  • Spin-flavor separation and non-Fermi-liquid behavior in the multichannel Kondo problem: a large-N approach 

    COX, D. L.; RUCKENSTEIN, A. E. (AMERICAN PHYSICAL SOC, 1993-09-06)
    We present an analytical solution of a SU(N)×SU(M) generalization of the multichannel single-impurity Kondo model in the limit N→∞, M→∞, with γ=M/N fixed. Non-Fermi-liquid behavior of the single electron Green function and ...
  • Low-temperature spin-diffusion in a spin-polarized Fermi gas 

    GOLOSOV, D. I.; RUCKENSTEIN, A. E. (AMERICAN PHYSICAL SOC, 1995-02-27)
    We present a finite temperature calculation of the transverse spin-diffusion coefficient D⊥ in a dilute degenerate Fermi gas, in the presence of a small external magnetic field H. While the longitudinal diffusion coefficient ...
