Two-particle tunneling and the impact of interaction

Quantum Physics 2024-09-24 v1

Abstract

We analyze the tunneling of two bosons in a double-well, for contact, soft-, and hard-core Coulomb interaction of tunable strength. Transitions from correlated to uncorrelated tunneling of the left well's two-particle ground state are due to resonances with states with one particle in either well. Their abundance and dependence on the interaction strength is indicative of the interaction type.
