| Abstract: | We extend the approach of solving master equations for density matrices by
projecting it onto the thermal entangled state representation (Hong-Yi Fan
and Jun-Hua Chen, J. Phys. A35 (2002) 6873) to two-mode case. In this
approach the two-photon master equations can be directly and conveniently
converted into c-number partial differential equations. As an example, we
solve the typical master equation for two-photon process in some limiting
cases. |
