Quantum breathers in capacitively coupled Josephson junctions: Correlations, number conservation, and entanglement
R. A. Pinto, S. Flach
We consider the classical and quantum dynamics of excitations in a system of two capacitively coupled Josephson junctions. In the classical case the equations of motion admit discr…

Quantum localized modes in capacitively coupled Josephson junctions
R. A. Pinto, S. Flach
We consider the quantum dynamics of excitations in a system of two capacitively coupled Josephson junctions. Quantum breather states are found in the middle of the energy spectrum…

Quantum q-breathers in a finite Bose-Hubbard chain: The case of two interacting bosons
Jean Pierre Nguenang, R. A. Pinto, Sergej Flach
We study the spectrum and eigenstates of the quantum discrete Bose-Hubbard Hamiltonian in a finite one-dimensional lattice containing two bosons. The interaction between the bosons…
