An energy-based stability criterion for solitary traveling waves in Hamiltonian lattices
Xu, Haitao; Cuevas-Maraver, Jesús; Kevrekidis, Panayotis G.; Vainchtein, Anna (The Royal Society, 2017)In this work, we revisit a criterion, originally proposed in [Nonlinearity 17, 207 (2004)], for the stability of solitary ...

PT -Symmetric dimer in a generalized model of coupled nonlinear oscillators
Cuevas-Maraver, Jesús; Khare, Avinash; Kevrekidis, Panayotis G.; Xu, Haitao; Saxena, Avadh (Springer, 2015)In the present work, we explore the case of a general PT -symmetric dimer in the context of two both linearly and nonlinearly ...

Stability of traveling waves in a driven Frenkel–Kontorova model
Vainchtein, Anna; Cuevas-Maraver, Jesús; Kevrekidis, Panayotis G.; Xu, Haitao (Elsevier, 2020-06)In this work we revisit a classical problem of traveling waves in a damped Frenkel–Kontorova lattice driven by a constant ...

Unifying perspective: solitary traveling waves as discrete breathers in Hamiltonian lattices and energy criteria for their stability
Cuevas-Maraver, Jesús; Kevrekidis, Panayotis G.; Vainchtein, Anna; Xu, Haitao (American Physical Society, 2017)In this work, we provide two complementary perspectives for the (spectral) stability of solitary traveling waves in ...
