Fragility of the Schrödinger Cat in thermal environments

Abstract We describe the decoherence instability of Schrödinger Cat states in the two-site Bose-Hubbard model with an attractive on-site interaction between particles. For N particles with onsite attractive energy U and hopping amplitude between sites t, Cat states exist for $$u\equiv \frac{UN}{2t}&...
