Non-equilibrium phase transition in the Brownian Ising Model: field theory, renormalization group, and exact results
Mattia Scandolo, Luca Di Carlo
We present a complete field-theoretical renormalization-group (RG) analysis of the Brownian Ising Model (BIM), in which a order parameter is coupled to a passive con…

Non-equilibrium coupling to a diffusing density breaks Ising universality
Mattia Scandolo, Johannes Pausch, Michael E. Cates +1
The Ising universality class is remarkably robust to non-equilibrium perturbations, which generically flow to zero under renormalization. We show that this robustness fails when an…

Monte Carlo, blocking, and inference: How to measure the renormalization group flow
Luca Di Carlo
Renormalization group theory is a powerful and intriguing technique with a wide range of applications. One of the main successes of renormalization group theory is the description…
