Structural localization in the Classical and Quantum Fermi-Pasta-Ulam Model
Graziano Amati, Tanja Schilling
We study the statistics and short-times dynamics of the classical and the quantum Fermi-Pasta-Ulam chain in thermal equilibrium. We analyze the distributions of single-particle con…

Reconsidering the structure of nucleation theories
Anja Kuhnhold, Hugues Meyer, Graziano Amati +2
We discuss the structure of the equation of motion that governs nucleation processes at first order phase transitions. From the underlying microscopic dynamics of a nucleating syst…

Memory effects in the Fermi-Pasta-Ulam Model
Graziano Amati, Hugues Meyer, Tanja Schilling
We study the Intermediate Scattering Function (ISF) of the strongly-nonlinear Fermi-Pasta Ulam Model at thermal equilibrium, using both numerical and analytical methods. From the m…
