M ay 2 00 9 Infinite operator-sum representation of density operator for a dissipative cavity with Kerr medium derived by virtue of entangled state representation

By using the thermo entangled state representation we solve the master equation for a dissipative cavity with Kerr medium to obtain density operators’ infinite operator-sum representation ρ (t) = P∞ m,n,l=0 Mm,n,lρ0M † m,n,l. It is noticeable that Mm,n,l is not hermite conjugate to M†m,n,l, nevertheless the normalization P∞ m,n,l=0 M † nm,,lMm,n,l = 1 still… CONTINUE READING
