Generalized Thermalization in an Integrable Lattice System
Amy C. Cassidy, Charles W. Clark, Marcos Rigol
After a quench, observables in an integrable system may not relax to the standard thermal values, but can relax to the ones predicted by the generalized Gibbs ensemble (GGE) [M. Ri…
Chaos and Thermalization in the one-dimensional Bose-Hubbard model in the classical-field approximation
Amy C. Cassidy
In this thesis, we present a comprehensive study of chaos and thermalization of the one-dimensional Bose-Hubbard Model (BHM) within the classical field approximation. Two quantitat…
Threshold for Chaos and Thermalization in One-Dimensional Mean-Field Bose-Hubbard Model
Amy C. Cassidy, Douglas Mason, Vanja Dunjko +1
We study the threshold for chaos and its relation to thermalization in the 1D mean-field Bose-Hubbard model, which in particular describes atoms in optical lattices. We identify th…
Formation of collective excitations in quasi-one dimensional metallic nanostructures: size and density dependance
Amy Cassidy, Ilya Grigorenko, Stephan Haas
We investigate theoretically the formation of collective excitations in atomic scale quasi-one dimensional metallic nanostructures. The response of the system is calculated within…
