Competition and coexistence of superconductivity and nematic order in a two-dimensional electron gas with quadrupolar interactions
Nei Lopes, Guilherme da Silva do Vale, Daniel G. Barci
We investigate the interplay between superconductivity and nematic order in a two-dimensional electron gas with competing pairing and quadrupolar forward-scattering interactions. T…

A covariant fermionic path integral for scalar Langevin processes with multiplicative white noise
Daniel G. Barci, Leticia F. Cugliandolo, Zochil González Arenas
We revisit the construction of the fermionic path-integral representation of overdamped scalar Langevin processes with multiplicative white noise, focusing on the covariance of the…

Dynamical phase transitions in two-dimensional Brownian Matter
Nathan O Silvano, Daniel G. Barci
We investigate collective behavior of a system of two-dimensional interacting Brownian particles in the hydrodynamic regime. By means of the Martin-Siggia-Rose-Jenssen-de Dominicis…
