Biphonons in the beta-Fermi-Pasta-Ulam model
(Physica. D: Nonlinear Phenomena, 2006)
Discrete breathers or intrinsic localized modes are nonlinear localized states that appear in several classical extended systems, such as for instance the Fermi-Paste-Ulam (FPU) model. In order to probe the quantum states ...
