Quantum statistics of the cyclotron resonance infrared detector
Daniel F. Walls · Journal of Physics A Mathematical and General · 1975
A quantum statistical analysis of the interaction of a radiation field with a system of electrons in cyclotron motion in a homogeneous field is presented. With high magnetic fields the interaction offers a possible means for detecting far infrared radiation. The redistribution of electrons in the Landau ladder of states after interaction with the field is calculated for various initial quantum states. The sensitivity of the detector is shown to depend crucially upon the initial quantum state of the electrons.
