چکیده

We analyze the electromagnetic scattering of massive particles with and without spin wherein one particle (or both) is electrically neutral. Using the techniques of effective field theory, we isolate the leading long distance effects, both classical and quantum mechanical. For spinless systems results are identical to those obtained earlier via more elaborate dispersive methods. However, we also find new results if either or both particles carry spin.

Theory of Gas Ionization by Intense Electromagnetic Fields

The distribution function of the electrons produced in the interaction between an intense electromagnetic wave and a neutral gas is derived and is shown to be nonequilibrium and anisotropic. By assuming that the time scale of gas ionization is much greater than the field period, it is shown that the electron distribution function formed in microwave and optical discharges has sharp anisotropy a...

Massive Photons: An Infrared Regularization Scheme for Lattice QCD+QED.

Standard methods for including electromagnetic interactions in lattice quantum chromodynamics calculations result in power-law finite-volume corrections to physical quantities. Removing these by extrapolation requires costly computations at multiple volumes. We introduce a photon mass to alternatively regulate the infrared, and rely on effective field theory to remove its unphysical effects. El...

Neutral shells and their applications in the design of electromagnetic shields

We present a simple design of electromagnetic shields for both field expelling and field confinement. Motivated by the concept of neutral inclusions in the theory of composites, we introduce two concepts of neutral shells, and use neutral shells to construct our designs of electromagnetic shields. We also discuss the relationships between electromagnetic shields and cloaking structures and argu...

Effects of electromagnetic field radiation on inducing physiological and biochemical changes in Satureja bachtiarica L. Fariba Ramezani Vishki1*, Ahmad Majd2, Taher Nejadsattari1 and Sedighe Arbabian2

As organisms exposed to various abiotic and biotic environmental impacts, plants are able to recognize and respond to their surrounding environment with high specificity. Electromagnetic field radiation is an important effective stress factor on growth and development of plants. Our research focused on plants grown from wet pretreated seeds with low frequency electromagnetic field exposure comp...
