Path integrals and stochastic calculus
Thibaut Arnoulx de Pirey, Leticia F. Cugliandolo, Vivien Lecomte +1
Path integrals are a ubiquitous tool in theoretical physics. However, their use is sometimes hindered by the lack of control on various manipulations -- such as performing a change…
Macroscopic Fluctuation Theory and Current Fluctuations in Active Lattice Gases
Tal Agranov, Sunghan Ro, Yariv Kafri +1
We study the current large deviations for a lattice model of interacting active particles displaying a motility-induced phase separation (MIPS). To do this, we first derive the exa…
Geometry of nonequilibrium reaction networks
Sara Dal Cengio, Vivien Lecomte, Matteo Polettini
The modern thermodynamics of discrete systems is based on graph theory, which provides both algebraic methods to define observables and a geometric intuition of their meaning and r…
