Quantum theory of coherent spontaneous and stimulated emissions
Autor: Eugene Y. C. Lu, Martin E. Smithers
Publikováno v: Physical Review A. 9:790-801
Photon statistics are obtained from exact closed-form solutions for both spontaneous and stimulated coherent emissions by a large number of two-level atoms in a Dicke state. Depending on the initial excitation level of the atoms, three types of photo

Theory of Ultrasonic Spin Echoes
Autor: Eugene Y. C. Lu, Peter A. Fedders
Publikováno v: Physical Review B. 8:5156-5162
A theory of ultrasonic spin echoes valid for arbitrary spin is presented. Semiclassical vector-model equations are constructed for components of the dipole and quadrupole moment tensors which are excited by ultrasonic pulses in analogy with the well-

Quantum Theory of Nonlinear Optical Processes with Time-Dependent Pump Amplitude and Phase: Frequency Conversion
Autor: Eugene Y. C. Lu
Publikováno v: Physical Review A. 8:1053-1061
The behavior of a simple theoretical model of a quantum-frequency converter with a time-dependent pump amplitude and phase is analyzed quantum mechanically. A sufficient condition ensuring periodic frequency conversion between the modes is found and

Distortionless propagation of zero‐degree pulses in degenerate resonant medium
Autor: Eugene Y. C. Lu, L. E. Wood
Publikováno v: Applied Physics Letters. 24:382-384
We give arguments to show that distortionless propagation of zero‐degree pulses is possible in an arbitrary degenerate resonant medium in agreement with recent experimental observation. In the case of overlapping Q (2) degeneracy, the analytic clos
