Inverse turbulent cascades and conformally invariant curves
D. Bernard, G. Boffetta, A. Celani +1
We offer a new example of conformal invariance far from equilibrium -- the inverse cascade of Surface Quasi-Geostrophic (SQG) turbulence. We show that temperature isolines are stat…

Quasi-Spin-Charge Separation and the Spin Quantum Hall Effect
D. Bernard, A. LeClair
We use quantum field theory methods to study the network model for the spin quantum hall transition. When the couplings are fine tuned in a certain way, the spin and charge degrees…

A One Dimensional Ideal Gas of Spinons, or Some Exact Results on the XXX Spin Chain with Long Range Interaction
D. Bernard, V. Pasquier, D. Serban
We describe a few properties of the XXX spin chain with long range interaction. The plan of these notes is: 1. The Hamiltonian 2. Symmetry of the model 3. The irreducible multiplet…
