Effect of droplet configurations within the functional renormalization group of the Ising model approaching the lower critical dimension
Ivan Balog, Lucija Nora FarkaÅ¡, Maroje MarohniÄ +1
We explore the application of the nonperturbative functional renormalization group (NPFRG) within its most common approximation scheme based on truncations of the derivative expans…

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…
