Nonlinear optical processes can be described as multiphoton scattering events in terms of high order perturbation theory. The standard procedure for quantitative calculation of high order terms is to impose a steady state condition on the perturbative radiation fields. In the present work, this condition will be lifted, and explicit...
Measurement of a quantum system - the process by which an observer gathers information about it - provides a link between the quantum and classical worlds. The nature of this process is the central issue for attempts to reconcile quantum and classical descriptions of physical processes. Here, we show that...
Perturbed Angular Correlations (PAC) spectroscopy is an effective
local probe technique often employed in the characterization of defects or
phase transitions in any of a variety of materials. This technique relies
upon the ability of probe nuclei to function as gauges of the magnetic
fields and electric field gradients local...
