Explicit solution of diffusion master equation under the action of linear resonance force via the thermal entangled state representation
Fei Yao, Ji‐Suo Wang, Tian-Niu Xu
Using the well-behaved features of the thermal entangled state representation, we solve the diffusion master equation under the action of a linear resonance force, and then obtain the infinitive operator-sum representation of the density operator. This approach may also be effective for treating other master equations. Moreover, we find that the initial pure coherent state evolves into a mixed thermal state after passing through the diffusion process under the action of the linear resonance force.
