Ising-like models on arbitrary graphs : The Hadamard way
Rémy Mosseri
We propose a generic framework to describe classical Ising-like models defined on arbitrary graphs. The energy spectrum is shown to be the Hadamard transform of a suitably defined…
Density of states and quantum phase transition in the thermodynamic limit of the Mermin central-spin model
Savannah Sterling Garmon, Pedro Ribeiro, Rémy Mosseri
We apply a spin-coherent states formalism to study the central-spin model with monochromatic bath and symmetric coupling (the Mermin model); in particular, we derive analytic expre…
Exact spectrum of the Lipkin-Meshkov-Glick model in the thermodynamic limit and finite-size corrections
P. Ribeiro, J. Vidal, R. Mosseri
The spectrum of the Lipkin-Meshkov-Glick model is exactly derived in the thermodynamic limit by means of a spin coherent states formalism. In the first step, a classical analysis a…
The Thermodynamical Limit of the Lipkin-Meshkov-Glick Model
P. Ribeiro, J. Vidal, R. Mosseri
A method based on the analyzis of the Majorana polynomial roots is introduced to compute the spectrum of the Lipkin-Meshkov-Glick model in the thermodynamical limit. A rich structu…
Random tilings of high symmetry: I. Mean-field theory
N. Destainville, M. Widom, R. Mosseri +1
We study random tiling models in the limit of high rotational symmetry. In this limit a mean-field theory yields reasonable predictions for the configurational entropy of free boun…
Arctic octahedron in three-dimensional rhombus tilings and related integer solid partitions
M. Widom, R. Mosseri, N. Destainville +1
Three-dimensional integer partitions provide a convenient representation of codimension-one three-dimensional random rhombus tilings. Calculating the entropy for such a model is a…
Fixed-boundary octagonal random tilings: a combinatorial approach
N. Destainville, R. Mosseri, F. bailly
Some combinatorial properties of fixed boundary rhombus random tilings with octagonal symmetry are studied. A geometrical analysis of their configuration space is given as well as…
Two-dimensional random tilings of large codimension: new progress
N. Destainville, M. Widom, R. Mosseri +1
Two-dimensional random tilings of rhombi can be seen as projections of two-dimensional membranes embedded in hypercubic lattices of higher dimensional spaces. Here, we consider til…
