Disorder-Induced Order in Two-Component Bose-Einstein Condensates
Résumé
We propose and analyze a general mechanism of disorder-induced order in two-component Bose-Einstein condensates, analogous to corresponding effects established for XY spin models. We show that a random Raman coupling induces a relative phase of π/2 between the two BECs and that the effect is robust. We demonstrate it in 1D, 2D and 3D at T=0 and present evidences that it persists for small T>0. Applications to phase control in ultracold spinor condensates are discussed.
