Quantum Brownian Motion in the Caldeira-Leggett Model with a Damped Environment
Lester Buxton, Marc-Thomas Russo, Jim Al-Khalili +1
We model a quantum system coupled to an environment of damped harmonic oscillators by following the approach of Caldeira-Leggett and adopting the Caldirola-Kanai Lagrangian for the…
Master equation for non-Markovian quantum Brownian motion: The emergence of lateral coherences
Sapphire Lally, Nicholas Werren, Jim Al-Khalili +1
Understanding the behaviour of a quantum system coupled to its environment is of fundamental interest in the general field of quantum technologies. It also has important repercussi…
Streamer branching rationalized by conformal mapping techniques
B. Meulenbroek, A. Rocco, U. Ebert
Spontaneous branching of discharge channels is frequently observed, but not well understood. We recently proposed a new branching mechanism based on simulations of a simple continu…
Branching of negative streamers in free flight
Andrea Rocco, Ute Ebert, Willem Hundsdorfer
We recently have shown that a negative streamer in a sufficiently high homogeneous field can branch spontaneously due to a Laplacian instability, rather than approach a stationary…
Kinematic reduction of reaction-diffusion fronts with multiplicative noise: Derivation of stochastic sharp-interface equations
A. Rocco, L. Ramirez-Piscina, J. Casademunt
We study the dynamics of generic reaction-diffusion fronts, including pulses and chemical waves, in the presence of multiplicative noise. We discuss the connection between the reac…
Is the Stillinger and Weber decomposition relevant for coarsening models?
A. Crisanti, F. Ritort, A. Rocco +1
We study three kinetic models with constraint, namely the Symmetrically Constrained Ising Chain, the Asymmetrically Constrained Ising Chain, and the Backgammon Model. All these mod…
