Diffusion of labeled particles on one-dimensional chains
S. Alexander,P. Pincus +1 more
TL;DR: In this paper, the long-time behavior of a labeled particle on a one-dimensional chain is studied and it is shown that the long time behavior is dominated by density fluctuations leading to a ε(n 2 ) dependence of the mean square deviation in agreement with Monte Carlo results of Richards.

High-Temperature Thermodynamics of the Strongly Correlated Hubbard Model at Arbitrary Electron Density
G. Beni,P. Pincus,Daniel Hone +2 more
TL;DR: In this article, the authors considered the Hubbard model for electron correlations in solids in the narrowband regime where the intra-atomic Coulomb repulsion is large compared to the bandwidth, and performed a high-temperature pertubation expansion in the bandwidth to lowest order for the grand partition function.

Percolation of conducting polymers on a gel
TL;DR: Fizazi reported evidence of conducting paths at extremely small volume fractions of conducting polymer in a polymer gel as mentioned in this paper, orders of magnitude below that required for percolation of the soluble conducting polymer alone.

Thermodynamic properties of the dimerized half-filled-band Hubbard chain
U. Bernstein,P. Pincus +1 more
TL;DR: In this paper, the authors used thermodynamic perturbation theory to treat the half-filled band case, taking the interdimer transfer as the perturbations term, and gave the energy, specific heat, and magnetic susceptibility as functions of temperature for the unperturbed case and for the first non-vanishing order in the permutation.
