Coherent control of quantum collapse in a Bosonic Josephson junction by modulation of the scattering length

Abstract: By means of a temporal-periodic modulation of the s-wave scattering length, a procedure to control the evolution of an initial atomic coherent state associated with a Bosonic Josephson junction is presented. The scheme developed has a remarkable advantage of avoiding the quantum collapse of the state due to phase and number diffusion. This kind of control could prove useful for atom interferometry using BECs, where the interactions limit the evolution time stage within the interferometer, and where the modulat… Show more

“…It is invariant under rotations, minimal for spin-coherent states (V = j) and maximal whenever the spin expectation vanishes (in which case V = j(j + 1)) [23]; hence, it is maximal for anticoherent states. The total variance has proved a useful tool in different contexts such as entanglement quantification [27,28], entanglement classification under stochastic local operations and classical communication (SLOCC) [26], and control of coherence [29].…”

“…[10], we assume that the interaction between atoms belonging to different hyperfine states is weak and can be neglected, g 12 = g 21 = 0. Indeed, both intra-species and inter-species scattering lengths can be readily tuned in experiments by means of the Feshbach resonance [16,17], that is, one has some freedom in choosing their values. Also, it should be noted that intra-species dynamics rather depends on the difference of nonlinearity parameters…”

“…Coherent control has been applied in the context of ultracold atomic gases [8][9][10][11] and in particular to Bose-Einstein condensates (BEC) [12][13][14]. For instance, the control of the onset of self-trapping of a condensate in a periodically modulated double well has been demonstrated [15].…”
