Collapse and revival for a slightly anharmonic Hamiltonian

Alexandra Bakman, Hagar Veksler, Shmuel Fishman

Research output: Contribution to journalArticlepeer-review


The effect of quantum collapse and revival is a fascinating interference phenomenon. In this paper the phenomenon is studied analytically and numerically for a simple system, a slightly anharmonic oscillator. The initial wave-function corresponds to a displaced ground state of a harmonic oscillator. Possible experimental realizations for cold atoms are discussed in detail.
