Exact generating function of a zero-dimensional supersymmetric non-linear sigma model
Adam Rançon, Ivan Balog
We compute exactly the generating function of a supersymmetric non-linear sigma model describ-ing random matrices belonging to the unitary class. Although an arbitrary source expli…
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…
Conformal invariance in the nonperturbative renormalization group: a rationale for choosing the regulator
Ivan Balog, Gonzalo De Polsi, Matthieu Tissier +1
Field-theoretical calculations performed in an approximation scheme often present a spurious dependence of physical quantities on some unphysical parameters associated with the det…
Precision calculation of critical exponents in the universality classes with the nonperturbative renormalization group
Gonzalo De Polsi, Ivan Balog, Matthieu Tissier +1
We compute the critical exponents , and of models for various values of by implementing the derivative expansion of the nonperturbative renormalization group…
