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 computing the same in case of the Ising model \cite{Sahu:2025bkp}. We show that even for the $O(n)$ model, there exists not…

Duality symmetry, zero energy modes and boundary spectrum of the sine-Gordon/massive Thirring model

Parameshwar R Pasnoori, Ari Mizel, Patrick Azaria

We solve the one-dimensional massive Thirring model, which is equivalent to the one-dimensional sine-Gordon model, with two types of Dirchlet boundary conditions: open boundary conditions (OBC) and twisted open boundary conditions ($\widehat{\text{OBC}}$). The system exhibits a duality symmetry…

Evidence and quantification of memory effects in competitive first-passage events

Maxim Dolgushev, Toni Vieira Mendes, Benjamin Gorin, Kaili Xie, Nicolas Levernier, Olivier Bénichou, Hamid Kellay, Raphaël Voituriez, Thomas Guérin

Splitting probabilities quantify the likelihood of a given outcome out of competitive events. This key observable of random walk theory, historically introduced as the gambler’s ruin problem, is well understood for memoryless (Markovian) processes. However, in complex systems such as polymer fluids…

Probability Distributions of the order parameter of the Ising Model at two loops

Sankarshan Sahu

There exists an entire family of universal PDFs of the magnetization mode of the three dimensional Ising model parameterized by $\zeta = \lim_{L,\xi_{\infty}}L/\xi_{\infty}$ which is the ratio of the system size $L$ to the bulk correlation length $\xi_{\infty}$ with both the thermodynamic limit and…
