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

Artificial square ice and related dipolar nanoarrays
Gunnar Moller 1, R. Moessner 2 Physical Review Letters 96 (2006) 237202 We study a frustrated dipolar array recently manufactured lithographically by Wang {\em et al.} [Nature {\bf 439}, 303 (2006)] in order to realize the square ice model in an artificial structure. We discuss models for thermodynamics and dynamics of this system. We show that an ice regime

Application of a two-length scale field theory to the solvation of charged molecules: I. Hydrophobic effect revisited
G. Sitnikov 1, 2, S. Nechaev 3, M. D. Taran 4, A. Muryshev 2 Journal of Chemical Physics 124 (2006) 094501 On a basis of a two-length scale description of hydrophobic interactions we develop a continuous self-consistent theory of solute-water interactions which allows to determine a hydrophobic layer of a solute molecules of any geometry with explicit account of solvent structure described by its correlation
Anderson localization of elementary excitations in a one dimensional Bose-Einstein condensate
Nicolas Bilas 1, Nicolas Pavloff 1 European Physical Journal D 40 (2006) 387-397 We study the elementary excitations of a transversely confined Bose-Einstein condensate in presence of a weak axial random potential. We determine the localization length (i) in the hydrodynamical low energy regime, for a domain of linear densities ranging from the Tonks-Girardeau to the transverse Thomas-Fermi regime,
