Superposition states of ultracold bosons in rotating rings with a weak potential barrier
Superposition states ultracold bosons weak potential barrier
2010/11/23
We study ultracold bosons in a one-dimensional rotating ring lattice with a weak potential barrier well below unit filling. Due to the potential barrier the eigenstates are superpositions of different...

We study cold atomic gases with a contact interaction and confined into one-dimension. Crossing
the confinement induced resonance the correlation between the bosons increases, and introduces an effec...
