Nonclassical states in strongly correlated bosonic ring ladders
Nonclassical states in strongly correlated bosonic ring ladders
We study the ground state of a bosonic ring ladder under a gauge flux in the vortex phase, corresponding to the case where the single-particle dispersion relation has two degenerate minima. By combining exact diagonalization and an approximate fermionization approach we show that the ground state of the system evolves …
