Hamiltonian flocks: Time-Reversal Symmetry and its consequences
Mathias Casiulis, Leticia F. Cugliandolo
The fluctuation-dissipation theorem is a hallmark of equilibrium systems that stems from their time-reversal symmetry. In many non-equilibrium systems, in particular active ones, e…
Geometry and localization: Probing Localization Landscape Theory on the Bethe Lattice
Lorenzo Tonetti, Leticia F. Cugliandolo, Marco Tarzia
The Localization Landscape Theory (LLT) offers a classical analogy for understanding Anderson localization through an effective confining potential, whose percolation threshold has…
Critical quench dynamics of Wegner's gauge model: a geometric perspective
Ramgopal Agrawal, Leticia F. Cugliandolo, Marco Picco
Wegner's gauge model is the earliest formulation of pure lattice gauge theory and predicts the topological nature of the confinement-deconfinement transition. In thr…
Active Quantum Particles from Engineered Dissipation
Jeanne Gipouloux, Matteo Brunelli, Leticia Cugliandolo +2
We introduce and characterize different models for an active quantum particle where activity arises from engineered dissipation-- specifically, from a suitably coupled nonequilibri…
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…
Universal Coarsening and Giant-Cluster Formation in Growing Interfaces
Renan A. L. Almeida, Tiago J. Oliveira, Jeferson J. Arenzon +1
Clusters formed by fluctuations of two-dimensional (2D) directed interfaces around a threshold level have been extensively studied at equilibrium and in nonequilibrium steady state…
