Frustrated Bose ladder with extended range density-density interaction
Sourav Biswas, E. Rico, Tobias Grass
When hard-core bosons on a two-leg ladder get frustrated by ring exchange interactions, the elusive d-wave Bose liquid (DBL) can be stabilized, a bosonic analog of a correlated met…

Ring-exchange physics in a chain of three-level ions
Sourav Biswas, E. Rico, Tobias Grass
In the presence of ring exchange interactions, bosons in a ladder-like lattice may form the bosonic analogon of a correlated metal, known as the d-wave Bose liquid (DBL). In this p…
