Cyril Furtlehner 1, Stephane Ouvry 1 Modern Physics Letters B 9 (1995) 503-509 Motivated by topological bidimensional quantum models for distinguishable particles, and by Haldane\’s definition of mutual statistics for different species of particles, we propose a new class of one-dimensional $1/r_{ij}^2$ Calogero model with coupling constants $g_{ij}$ depending on the labels of the particles. We solve the groundstate […]

E. Bashkin 1, 2, N. Pavloff 3, J. Treiner. 3 Journal of Low Temperature Physics 99 (1995) 659-681 3He atoms dissolved in superfluid 4He may form dimers (3He)2 in two-dimensional geometries. We study dimer formation in films of dilute 3He-4He mixture. After designing a schematic 3He-3He interaction potential we calculate the dimer binding energy for various substrates. It is shown that 3He

Jean Desbois 1, Christine Heinemann 1, Stephane Ouvry 1 Physical Review D 51 (1995) 942-945 The computation of the $N$-cycle brownian paths contribution $F_N(\\alpha)$ to the $N$-anyon partition function is adressed. A detailed numerical analysis based on random walk on a lattice indicates that $F_N^{(0)}(\\alpha)= \\prod_{k=1}^{N-1}(1-{N\\over k}\\alpha)$. In the paramount $3$-anyon case, one can show that $F_3(\\alpha)$ is built by linear

Seligman 3, 4 Physics Letters B, Elsevier, 1994, 324, pp.263-266. <10.1016/0370-2693(94)90191-0> New statistical measures are applied to the previously compiled nuclear data ensemble in order to further test energy level fluctuations as well as the absence of correlations between levels and intensities. Data are found to

Leboeuf Patricio 1, Amaury Mouchet 2 Physical Review Letters 73 (1994) 1360 We compute the dispersion laws of chaotic periodic systems using the semiclassical periodic orbit theory to approximate the trace of the powers of the evolution operator. Aside from the usual real trajectories, we also include complex orbits. These turn out to be fundamental for a proper description
