Stability of quantum breathers
L. S. Schulman, D. Tolkunov, E. Mihokova
Using two methods we show that a quantized discrete breather in a 1-D lattice is stable. One method uses path integrals and compares correlations for a (linear) local mode with tho…

Structure and time-dependence of quantum breathers
L. S. Schulman, D. Tolkunov, E. Mihokova
Quantum states of a discrete breather are studied in two ways. One method involves numerical diagonalization of the Hamiltonian, the other uses the path integral to examine correla…
