Coulomb Scattering in a Strong Magnetic Field
The presence of a strong magnetic eld intrinsically changes the orbit of electrons in their Coulomb interactions with ions for a range of parameters. The characteristic scale for the orbit modi cation is r0 = (Zme=4 0B) where Ze is the ion charge, me the electron mass and B the magnetic eld strength. The scale length is comparable to the interparticle spacing when n 1=3 e r0 = (!pe=!ce) 2=3(Z=4...
متن کاملColour superconductivity in a strong magnetic field
We explore the effects of an applied strong external magnetic field in a three flavour massless colour superconductor. The long-range component of the B field that penetrates the superconductor enhances some quark condensates, leading to a different condensation pattern. The external field also reduces the flavour symmetries in the system, and thus it changes drastically the corresponding low e...
متن کاملNon-Relativistic Limit of Neutron Beta-Decay Cross-Section in the Presence of Strong Magnetic Field
One of the most important reactions of the URCA that lead to the cooling of a neutron star, is neutron beta-decay ( ). In this research, the energy spectra and wave functions of massive fermions taking into account the Anomalous Magnetic Moment (AMM) in the presence of a strong changed magnetic field are calculated. For this purpose, the Dirac-Pauli equation for charged and neutral fermions is ...
متن کاملPair production in a strong time-depending magnetic field: the effect of a strong gravitational field
We present the calculation of the probability production of an electron-positron pair in the presence of a strong magnetic field with time-varying strength. The calculation takes into account the presence of a strong, constant and uniform gravitational field in the same direction of the magnetic field. The results show that the presence of the gravitational field in general enhances very much t...
متن کاملPhoton-neutrino interactions in strong magnetic field
The two-photon two-neutrino interaction induced by magnetic field is investigated. In particular the processes γγ → νν̄ and γ → γνν̄ are studied in the presence of strong magnetic field. An effective Lagrangian and partial amplitudes of the processes are presented. Neutrino emissivities due to the reactions γγ → νν̄ and γ → γνν̄ are calculated taking into account of the photon dispersion and large ...
