Classical dimers with aligning interactions on the square lattice

Fabien Alet 1, 2, Yacine Ikhlef 2, 3, Jesper Lykke Jacobsen 2, 3, Gregoire Misguich 2, Vincent Pasquier 2 Physical Review E: Statistical, Nonlinear, and Soft Matter Physics 74 (2006) 041124 We present a detailed study of a model of close-packed dimers on the square lattice with an interaction between nearest-neighbor dimers. The interaction favors parallel alignment of dimers, resulting in a low-temperature crystalline phase. With large-scale Monte

Casimir interaction between a plate and a cylinder

T. Emig 1, 2, R. L. Jaffe 3, 4, M. Kardar 4, A. Scardicchio 3, 4 Physical Review Letters 96 (2006) 080403 We find the exact Casimir force between a plate and a cylinder, a geometry intermediate between parallel plates, where the force is known exactly, and the plate–sphere, where it is known at large separations. The force has an unexpectedly weak decay \sim L/(H^3 \ln(H/R))

Bosonization, Pairing, and Superconductivity of the Fermionic Tonks-Girardeau Gas

M. D. Girardeau 1, A. Minguzzi 2, 3 Physical Review Letters 96 (2006) 080404 We determine some exact static and time-dependent properties of the fermionic Tonks-Girardeau (FTG) gas, a spin-aligned one-dimensional Fermi gas with infinitely strongly attractive zero-range odd-wave interactions. We show that the two-particle reduced density matrix exhibits maximal off-diagonal long-range order, and on a ring an FTG gas

Average ground-state energy of finite Fermi systems

M. Centelles 1, P. Leboeuf 2, A. G. Monastra 3, J. Roccia 2, P. Schuck 4, X. Vinas 1 Physical Review C 74 (2006) 034332 Semiclassical theories like the Thomas-Fermi and Wigner-Kirkwood methods give a good description of the smooth average part of the total energy of a Fermi gas in some external potential when the chemical potential is varied. However, in systems with a fixed number
