Unraveling anomalous relaxation effects in the thermodynamic limit
Emilio Pomares, VÃctor MartÃn-Mayor, Antonio Lasanta +1
We address two central open problems in the theory of anomalous Mpemba-like relaxations: their extension beyond one spatial dimension and their consistent formulation in the thermo…

The cost of speed: Time-optimal thermal control of trapped Brownian particles
Miguel Ibanez, Antonio Patron-Castro, Antonio Lasanta +3
A thermal analogue of the classical brachistochrone problem, which minimizes the connection time between two equilibrium states of harmonically confined Brownian particles, has rec…

Spacetime symmetries and geometric diffusion
Marc Basquens, Antonio Lasanta, Emanuel Mompó +2
We examine relativistic diffusion through the frame and observer bundles associated with a Lorentzian manifold . Our focus is on spacetimes with a non-trivial isometry group…
