Dissipation-Assisted Coherence Formation in a Spinor Quantum Gas
Dissipation-Assisted Coherence Formation in a Spinor Quantum Gas
We report the formation of magnetic eigenstates assisted by naturally occurring particle dissipation in a Bose-Einstein condensate of spin-2 ^{87}Rb atoms. Although the atomic interaction energetically favors the nonferromagnetic state, we observed the spontaneous evolution of an unpolarized spin state into the transverse ferromagnetic state. Under such dynamics, the spin-dependent …
