Momentum diffusion for coupled atom-cavity oscillators
It is shown that the momentum diffusion of free-space laser cooling has a natural correspondence in optical cavities when the internal state of the atom is treated as a harmonic oscillator. We derive a general expression for the momentum diffusion which is valid for most configurations of interest: The atom or the cavity or both can be probed by lasers, with or without the presence of traps ind...

متن کاملCavity mode emission in weakly coupled quantum dot--cavity systems.
We study the origin of bright leaky-cavity mode emission and its influence on photon statistics in weakly coupled quantum dot - semiconductor cavity systems, which consist of a planar photonic-crystal and several quantum dots. We present experimental measurements that show that when the system is excited above the barrier energy, then bright cavity mode emissions with nonzero detuning are domin...
متن کاملEdge states and interferometers in the Pfaffian and anti-Pfaffian states
We compute the tunneling current in a double point contact geometry of a quantum Hall system at filling fraction = 5 2 , as a function of voltage and temperature, in the weak tunneling regime. We quantitatively compare two possible candidates for the state at = 5 2 : the Moore-Read Pfaffian state, and its particle-hole conjugate, the anti-Pfaffian. We find that both possibilities exhibit the sa...
متن کاملDissipation-assisted quantum computation in atom-cavity systems
The principal obstacle to quantum information processing with many qubits is decoherence. One source of decoherence is spontaneous emission which causes loss of energy and information. Inability to control system parameters with high precision is another possible source of error. Strategies aimed at overcoming one kind of error typically increase sensitivity to others. As a solution we propose ...
