Decay of symmetry-protected quantum states
A. A. Bychek, D. N. Maksimov, A. R. Kolovsky
We study the decay of bosonic many-body states in the three well Bose-Hubbard chain where bosons in the central well can escape into a reservoir. For vanishing inter-particle inter…
Chaotic and regular dynamics in the three-site Bose-Hubbard model
A. A. Bychek, P. S. Muraev, D. N. Maksimov +1
We analyze the energy spectrum of the three-site Bose-Hubbard model. It is shown that this spectrum is a mixture of the regular and irregular spectra associated with the regular an…
NOON state of Bose atoms in the double-well potential via an excited state quantum phase transition
A. A. Bychek, D. N. Maksimov, A. R. Kolovsky
We suggest a simple scheme for creating a NOON state of repulsively interacting Bose atoms in the double-well potential. The protocol consists of two steps. First, by setting atom-…
