【报告摘要】：We introduce a theoretical scheme to study the weakly interacting Bose gases with two-particle losses. We show that both the two-body interactions and losses in atomic gases may be tuned by controlling the inelastic scattering process between atoms by an optical Feshbach resonance, and can be effectively described by a complex scattering length. Within this formalism, we apply the Bogoliubov approximation to solve the Lindblad master equation and derive dissipative analogues of the Gross–Pitaevskii equations. These equations can help us understand the dissipative many-body phenomena in atomic Bose gases.
