Momentum and Energy Transfer in an Ionospheric Critical Ionization Velocity Experiment

Momentum and energy transfer in an ionospheric critical ionization velocity experiment.

An Impact Ionization Model for Two-Carrier Energy-Momentum Simulation

Conventional numerical drift-diffusion simulation assumes that the carriers are in equilibrium with the local electric field at all times. It is well-known however that at high fields, significant carrier heating can occur and these high temperatures may affect the device response. Thus, a wide variety of hydrodynamic or energy/momentum numerical models have been developed to allow the simulati...

Energy and Momentum Transfer in Air Shocks

A series of one-dimensional studies is presented to reveal basic aspects of momentum and energy transfer to plates in air blasts. Intense air waves are initiated as either an isolated propagating wave or by the sudden release of a highly compressed air layer. Wave momentum is determined in terms of the energy characterizing the compressed layer. The interaction of intense waves with freestandin...

Quantum theory of longitudinal momentum transfer in above-threshold ionization

Angular momentum conservation in dipolar energy transfer.

Conservation of angular momentum is a familiar tenet in science but has seldom been invoked to understand (or predict) chemical processes. We have developed a general formalism based on Wigner's original ideas concerning angular momentum conservation to interpret the photo-induced reactivity of two molecular donor-acceptor assemblies with physical properties synthetically tailored to facilitate...
