Density-Induced Breaking of Pairs in the Attractive Hubbard Model
Bumsoo Kyung, E. G. Klepfish, P. E. Kornilovitch
A conserving T-matrix approximation is applied to the two-dimensional attractive Hubbard model in the low-density regime. A set of self-consistent equations is solved in the real-f…
Results on Finite Density QCD
I. M. Barbour, S. E. Morrison, E. G. Klepfish +2
A brief summary of the formulation of QCD at finite chemical potental, , is presented. The failure of the quenched approximation to the problem is reviewed. Results are presente…
Frequency-dependent spin susceptibility in the two-dimensional Hubbard model
C. E. Creffield, P. E. Kornilovitch, E. G. Klepfish +2
A Quantum Monte Carlo calculation of dynamical spin susceptibility in the half-filled 2D Hubbard model is presented for temperature and an intermediate on-site repulsion $…
Critical mass in nonzero temperature QCD with staggered fermions
I. M. Barbour, A. J. Bell, E. G. Klepfish
The behaviour of the chiral condensate in QCD is investigated by means of a study of the distribution of the zeros of the partition function in the complex quark mass plane. Simula…
