The Dissipative Bose-Hubbard Model. Methods and Examples
G. Kordas, D. Witthaut, P. Buonsante +4
Open many-body quantum systems have attracted renewed interest in the context of quantum information science and quantum transport with biological clusters and ultracold atomic gas…
Quantum Criticality in a Bosonic Josephson Junction
P. Buonsante, R. Burioni, E. Vescovi +1
In this paper we consider a bosonic Josephson junction described by a two-mode Bose-Hubbard model, and we thoroughly analyze a quantum phase transition occurring in the system in t…
Autocatalytic reaction-diffusion processes in restricted geometries
E. Agliari, R. Burioni, D. Cassi +1
We study the dynamics of a system made up of particles of two different species undergoing irreversible quadratic autocatalytic reactions: . We especially focus on th…
Phase-ordering kinetics on graphs
R. Burioni, D. Cassi, F. Corberi +1
We study numerically the phase-ordering kinetics following a temperature quench of the Ising model with single spin flip dynamics on a class of graphs, including geometrical fracta…
Probing the local structure: macromolecular combs in external fields
R. Burioni, D. Cassi, A. Blumen
Recent experimental methods allow to monitor the response of macromolecules to locally applied fields, complementing usual, mesoscopic techniques. Based on the Rouse-model and its…
Diffusive Thermal Dynamics for the Ising Ferromagnet
P. Buonsante, R. Burioni, D. Cassi +1
We introduce a thermal dynamics for the Ising ferromagnet where the energy variations occurring within the system exhibit a diffusive character typical of thermalizing agents such…
