Pair tunneling from dipolar interactions in a double-well Bose-Hubbard model induces ground-state parity modulations, qualitatively alters quantum phase transitions to NOON states, shifts critical points, and modifies macroscopic quantum self-trapping conditions.

Equilibrium and dynamical quantum phase transitions in dipolar atomic Josephson junctions
Pair tunneling from dipolar interactions in a double-well Bose-Hubbard model induces ground-state parity modulations, qualitatively alters quantum phase transitions to NOON states, shifts critical points, and modifies macroscopic quantum self-trapping conditions.
