On the breakdown of dimensional reduction and supersymmetry in random-field models
Gilles Tarjus, Matthieu Tissier, Ivan Balog
We discuss the breakdown of the Parisi-Sourlas supersymmetry (SUSY) and of the dimensional-reduction (DR) property in the random field Ising and O() models as a function of spac…
Dimensional reduction breakdown and correction to scaling in the random-field Ising model
Ivan Balog, Gilles Tarjus, Matthieu Tissier
We provide a theoretical analysis by means of the nonperturbative functional renormalization group (NP-FRG) of the corrections to scaling in the critical behavior of the random-fie…
Comment on "Evidence for Supersymmetry in the Random-Field Ising Model at D=5''
Ivan Balog, Gilles Tarjus, Matthieu Tissier
In a recent letter, Fytas et al. [Phys. Rev. Lett. 122, 240603 (2019)] study the critical point of the equilibrium random-field Ising model (RFIM) in by means of state-of-art…
Benchmarking the nonperturbative functional renormalization group approach on the random elastic manifold model in and out of equilibrium
Ivan Balog, Gilles Tarjus, Matthieu Tissier
Criticality in the class of disordered systems comprising the random-field Ising model (RFIM) and elastic manifolds in a random environment is controlled by zero-temperature fixed…
Disorder-driven quantum transition in relativistic semimetals: functional renormalization via the porous medium equation
Ivan Balog, David Carpentier, Andrei A. Fedorenko
In the presence of randomness, a relativistic semimetal undergoes a quantum transition towards a diffusive phase. A standard approach relates this transition to the Gross-Ne…
Fixed points and their stability in the functional renormalization group of random field models
Maxime Baczyk, Gilles Tarjus, Matthieu Tissier +1
We consider the zero-temperature fixed points controlling the critical behavior of the -dimensional random-field Ising, and more generally , models. We clarify the nature…
Same universality class for the critical behavior in and out of equilibrium in a quenched random field
Ivan Balog, Matthieu Tissier, Gilles Tarjus
The random-field Ising model (RFIM) is one of the simplest statistical-mechanical models that captures the anomalous irreversible collective response seen in a wide range of physic…
Critical scaling in random-field systems: 2 or 3 independent exponents?
Gilles Tarjus, Ivan Balog, Matthieu Tissier
We show that the critical scaling behavior of random-field systems with short-range interactions and disorder correlations cannot be described in general by only two independent ex…
