Our paper “Creation and characterization of matter-wave breathers” has been accepted for publication in Physical Review Letters. A breather is an excited state of a soliton. Since it is a superposition of multiple fundamental solitons, its density profile oscillates periodically. We have created matter-wave breathers of two and three solitons in a 7Li Bose-Einstein condensate (BEC) by quenching the atomic interaction. This work paves ways for studying beyond-mean-field quantum effects in a BEC.
