Semilinear Response
Michael Wilkinson, Bernhard Mehlig, Doron Cohen
We discuss the response of a quantum system to a time-dependent perturbation with spectrum Φ(ω). This is characterised by a rate constant D describing the diffusion of occupation p…
Staggered Ladder Spectra
E. Arvedson, M. Wilkinson, B. Mehlig +1
We exactly solve a Fokker-Planck equation by determining its eigenvalues and eigenfunctions: we construct nonlinear second-order differential operators which act as raising and low…
Clustering in mixing flows
K. Duncan, B. Mehlig, S. Ostlund +1
We calculate the Lyapunov exponents for particles suspended in a random three-dimensional flow, concentrating on the limit where the viscous damping rate is small compared to the i…
