Supersymmetry Without Time-Reversal Invariance in Model A: A FRG perspective

Sankarshan Sahu, Bertrand Delamotte, Adam RanÃ§on +1

We show that, contrary to common belief, supersymmetry alone is not sufficient in Model A dynamics to ensure relaxation toward a stationary state satisfying time-reversal invarianc…

Critical Probability Distributions of the order parameter at two loops II: $O (n)$ universality class

Sankarshan Sahu

We show how to compute the probability distributions of the order parameter of the $O (n)$ model at two-loop order of perturbation theory generalizing the methods developed for comp…

Critical Probability Distributions of the order parameter at two loops I: Ising universality class

Sankarshan Sahu

There exists an entire family of universal PDFs of the magnetization mode of the three dimensional Ising model parameterized by $I^¶ = lim_{L, I^¾_{\infty}} L / I^¾_{\infty}$ which is the…

Generalization of the Central Limit Theorem to Critical Systems: Revisiting Perturbation Theory

Sankarshan Sahu, Bertrand Delamotte, Adam RanÃ§on

The Central Limit Theorem does not hold for strongly correlated stochastic variables, as is the case for statistical systems close to criticality. Recently, the calculation of the…
