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…

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…
