Positive effect of scattering strength of a microtoroidal cavity on atomic entanglement evolution
Jiasen Jin, Chang‐shui Yu, Pei Pei, He‐Shan Song · Physical Review A · 2010
We show that the rough surface of a microtoroidal cavity (scattering strength) can play a constructive role by studying the entanglement of two atoms surrounding the cavity. Analytical results show that appropriate surface roughness can enhance the atomic entanglement. In particular, the rough surface can also compensate for the loss of maximal entanglement during the evolution caused by cavity leakage and atomic spontaneous emission.
