Two infrared Yang-Mills solutions in stochastic quantization and in an effective action formalism [PDF]

, 2012
Three decades of work on the quantum field equations of pure Yang-Mills theory have distilled two families of solutions in Landau gauge. Both coincide for high (Euclidean) momentum with known perturbation theory, and both predict an infrared suppressed ...

Asymptotic symmetries of difference equations on a lattice [PDF]

, 2005
It is known that many equations of interest in Mathematical Physics display solutions which are only asymptotically invariant under transformations (e.g. scaling and/or translations) which are not symmetries of the considered equation.

Adaptive Wavelet Collocation Method for Simulation of Time Dependent Maxwell's Equations [PDF]

, 2012
This paper investigates an adaptive wavelet collocation time domain method for the numerical solution of Maxwell's equations. In this method a computational grid is dynamically adapted at each time step by using the wavelet decomposition of the field at ...

Thermodynamic Bethe Ansatz with Haldane Statistics [PDF]

, 1998
We derive the thermodynamic Bethe ansatz equation for the situation inwhich the statistical interaction of a multi-particle system is governed by Haldane statistics. We formulate a macroscopical equivalence principle for such systems.

Critical behaviour of the two-dimensional Ising susceptibility

, 2000
We report computations of the short-distance and the long-distance (scaling) contributions to the square-lattice Ising susceptibility in zero field close to T_c.

Fake supersymmetry versus Hamilton-Jacobi [PDF]

, 2012
We explain when the first-order Hamilton-Jacobi equations for black holes (and domain walls) in (gauged) supergravity, reduce to the usual first-order equations derived from a fake superpotential.

Critical interface: twisting spin glasses at $T_c$

, 2010
We consider identical copies of spin glasses in finite dimension coupled at the boundaries. This allows to identify the spin glass analogous of twisted boundary conditions in ferromagnetic system and leads to the definition of an interface free-energy ...

Lagrangian and Hamiltonian two-scale reduction [PDF]

, 1988
Studying high-dimensional Hamiltonian systems with microstructure, it is an important and challenging problem to identify reduced macroscopic models that describe some effective dynamics on large spatial and temporal scales.

Hierarchical Structure of Azbel-Hofstader Problem: Strings and loose ends of Bethe Ansatz

, 1997
We present numerical evidence that solutions of the Bethe Ansatz equations for a Bloch particle in an incommensurate magnetic field (Azbel-Hofstadter or AH model), consist of complexes-"strings".

Bulk Viscosity in Holographic Lifshitz Hydrodynamics [PDF]

, 2013
We compute the bulk viscosity in holographic models dual to theories with Lifshitz scaling and/or hyperscaling violation, using a generalization of the bulk viscosity formula derived in arXiv:1103.1657 from the null focusing equation. We find that only a
