From: Symmetry between repulsive and attractive interactions in driven-dissipative Bose-Hubbard systems
Boson number expectation value on site 1 as function of varying drive strength (Ω) for a uniform trimer. Gray bars correspond to the lower sign choice in the parameters listed in Table 1(a), Case 2; and orange bars correspond to the upper sign choice. The transformation from the lower sign choice to the upper sign choice is not number-conserving and the boson number expectation value is not invariant.
