Far-from-equilibrium state in a weakly dissipative model
Eric Bertin, Olivier Dauchot
We address, on the example of a simple solvable model, the issue of whether the stationary state of dissipative systems converges to an equilibrium state in the low dissipation lim…
Directed percolation criticality in turbulent liquid crystals
Kazumasa A. Takeuchi, Masafumi Kuroda, Hugues Chaté +1
We experimentally investigate the critical behavior of a phase transition between two topologically different turbulent states of electrohydrodynamic convection in nematic liquid c…
Scaling of hysteresis loops at phase transitions into a quasiabsorbing state
Kazumasa A. Takeuchi
Models undergoing a phase transition to an absorbing state weakly broken by the addition of a very low spontaneous nucleation rate are shown to exhibit hysteresis loops whose width…
Spatial correlations in the dynamics of glassforming liquids: Experimental determination of their temperature dependence
Cécile Dalle-Ferrier, Caroline Thibierge, Christiane Alba-Simionesco +6
We use recently introduced three-point dynamic susceptibilities to obtain an experimental determination of the temperature evolution of the number of molecules, N_corr, that are dy…
Quantum melting of a crystal of dipolar bosons
Christophe Mora, Olivier Parcollet, Xavier Waintal
We investigate the behaviour of dipolar bosons in two dimensions. We describe the large density crystalline limit analytically while we use quantum Monte-Carlo to study the melting…
Variational wave functions, ground state and their overlap
Christophe Mora, Xavier Waintal
An intrinsic measure of the quality of a variational wave function is given by its overlap with the ground state of the system. We derive a general formula to compute this overlap…
