Annals of Physics: Quasi-superfluid and quasi-mott phases of strongly interacting bosons in shallow optical lattice

"Quasi-superfluid and quasi-mott phases of strongly interacting bosons in shallow optical lattice", a work by S. Roy, R. Roy, A. Gammal, B. Chakrabarti, and B. Chatterjee, was published in Annals of Physics: https://doi.org/10.1016/j.aop.2024.169807.

This paper uses the MCTDHB method to uncover two new many-body phases of strongly interacting bosons in weak lattices—quasi-superfluid and quasi-Mott insulator—characterized by fragmentation and analyzed via coherence and entropy measures as the lattice depth increases.
