Mott transition in lattice boson models
Roberto Fernandez, Juerg Froehlich, Daniel Ueltschi
We use mathematically rigorous perturbation theory to study the transition between the Mott insulator and the conjectured Bose-Einstein condensate in a hard-core Bose-Hubbard model…
Krein's Theory applied to fluctuations of Lévy processes
Sonia Fourati
We give an interpretation of the bilateral exit problem for Lévy processes via the study of an elementary Markov chain. We exhibit a strong connection between this problem and Krei…
Monte Carlo Study of Phase Transitions in the Bond-Diluted 3D 4-State Potts Model
Christophe Chatelain, Bertrand Berche, Wolfhard Janke +1
Large-scale Monte Carlo simulations of the bond-diluted three-dimensional 4-state Potts model are performed. The phase diagram and the physical properties at the phase transitions…
Stability calculations for the ytterbium-doped fiber laser passively mode-locked through nonlinear polarization rotation
Mohamed Salhi, Herve Leblond, Francois Sanchez +2
We investigate theoretically a fiber laser passively mode-locked with nonlinear polarization rotation. A unidirectional ring cavity is considered with a polarizer placed between tw…
Experimental and theoretical study of the passively mode-locked Ytterbium-doped double-clad fiber laser
Herve Leblond, Mohamed Salhi, Ammar Hideur +3
We consider an Yb-doped double-clad fiber laser in a unidirectional ring cavity containing a polarizer placed between two half-wave plates. Depending on the orientation of the phas…
Partition functions and graphs: A combinatorial approach
Allan I. Solomon, Pawel Blasiak, Gerard Duchamp +2
Although symmetry methods and analysis are a necessary ingredient in every physicist's toolkit, rather less use has been made of combinatorial methods. One exception is in the real…
