Quantum Breathers in Electron-phonon Systems
W. Z. Wang, A. R. Bishop, J. T. Gammel +1
Quantum breathers are studied numerically in several electron-phonon coupled finite chain systems, in which the coupling results in intrinsic nonlinearity but with varying degrees…

Quantum Breathers in a Nonlinear Lattice
W. Z. Wang, J. Tinka Gammel, A. R. Bishop +1
We study nonlinear phonon excitations in a one-dimensional quantum nonlinear lattice model using numerical exact diagonalization. We find that multi-phonon bound states exist as ei…
