Relativistic quantum theory of cyclotron resonance in a medium

Relativistic cyclotron resonance shape in magnetic bottle geonium.

The thermally excited axial oscillation of the electron through the weak magnetic bottle needed for the continuous Stern-Gerlach effect modulates the cyclotron frequency and produces a characteristic approximately 12-kHz-wide vertical rise-exponential decline line shape of the cyclotron resonance. At the same time the relativistic mass shift decreases the frequency by approximately 200 Hz per c...

Relativistic Quantum Field Theory

Theory of spin-split cyclotron resonance in the extreme quantum limit.

We present an interpretation of recent cyclotron resonance experiments on the two-dimensional electron gas in GaAs/AlGaAs heterostructures. We show that the observed dependence of the resonance spectrum on Landau level occupancy and temperature arises from the interplay of three factors: spin-splitting of the cyclotron frequency; thermal population of the two spin states; and coupling of the re...

A relativistic quantum theory of gravity

A relativistic quantum theory of gravity is proposed in which the gravitational interaction between particles is represented by distanceand velocity-dependent potentials. The Poincaré invariance, the cluster separability, and the causality of this approach are established. The Hamiltonian for interacting massive particles and photons is formulated within the c−2 approximation. The classical lim...

Cyclotron Line Formation in a Relativistic Outflow

There is mounting evidence that, if gamma-ray bursters are Galactic in origin, they are located in a Galactic corona at distances greater than 100 kpc. This has created a need to explore new models of cyclotron line formation. In most previous calculations the line-forming region was modeled as a static slab of plasma, optically thin to continuum scattering, and threaded by a magnetic field of ...
