# Management of the Correlations of Ultracold Bosons in Triple Wells. (arXiv:1802.02407v1 [cond-mat.quant-gas])

functions of many-body systems that are generally eluding detection and

manipulation. Herein, we investigate the ground state of bosons in a tilted

triple-well potential and characterize the many-body state by the eigenvalues

of its reduced one-body density matrix and Glauber correlation functions. We

unveil how the interplay between the interaction strength and the tilt can be

used to control the number of correlated wells as well as the fragmentation,

i.e. the number of macroscopic eigenvalues of the reduced one-body density

matrix.
