Drastic effects of damping mechanisms on the third-order optical nonlinearity
Kazuki Koshino, Hajime Ishihara
We have investigated the optical response of superradiant atoms, which undergoes three different damping mechanisms: radiative dissipation (), dephasing (), and nonradiat…

Quantum Zeno effect by general measurements
K. Koshino, A. Shimizu
It was predicted that frequently repeated measurements on an unstable quantum state may alter the decay rate of the state. This is called the quantum Zeno effect (QZE) or the anti-…

Two-photon nonlinearity in general cavity QED systems
Kazuki Koshino, Hajime Ishihara
We have investigated the two-photon nonlinearity at general cavity QED systems, which covers both weak and strong coupling regimes and includes radiative loss from the atom. The on…
