Signatures of Discrete Breathers in Coherent State Quantum
Kirill Igumenshchev, Misha Ovchinnikov, Panagiotis Maniadis +1
Discrete breathers (DBs) -- a spatial time-periodic localization of energy -- are predicted in a large variety of non-linear systems. Motivated by the conceptual bridging of the DB…
Strain-induced interface reconstruction in epitaxial heterostructures
N. Lazarides, V. Paltoglou, P. Maniadis +2
We investigate in the framework of Landau theory the distortion of the strain fields at the interface of two dissimilar ferroelastic oxides that undergo a structural cubic-to-tetra…
Feigenbaum Cascade of Discrete Breathers in a Model of DNA
P. Maniadis, B. S. Alexandrov, A. R. Bishop +1
We demonstrate that period-doubled discrete breathers appear from the anti-continuum limit of the driven Peyrard-Bishop-Dauxois model of DNA. These novel breathers result from a st…
Nonlinear response and discrete breather excitation in driven micro-mechanical cantilever arrays
P. Maniadis, S. Flach
We explain the origin of the generation of discrete breathers (DBs) in experiments on damped and driven micromechanical cantilever arrays (M.Sato et al. Phys. Rev. Lett. {\bf 90},…
q-Symmetries in DNLS-AL chains and exact solutions of quantum dimers
Demosthenes Ellinas, Panagiotis Maniadis
Dynamical symmetries of Hamiltonians quantized models of discrete non-linear Schroedinger chain (DNLS) and of Ablowitz-Ladik chain (AL) are studied. It is shown that for -sites…
