Magnetic field induced neutrino chiral transport near equilibrium

Photon-Neutrino Interactions in Magnetic Field through Neutrino Magnetic Moment

We study the neutrino-photon processes like γγ → νν̄ in the presence of uniform external magnetic field for the case when neutrinos can couple to the electromagnetic field directly through their dipole magnetic moment and obtain the stellar energy loss. The process would be of special relevance in astrophysical situations where standard left-handed neutrinos are trapped and the right handed neut...

Neutrino transport: no asymmetry in equilibrium

A small asymmetry in the flux of neutrinos emitted by a hot newly-born neutron star could explain the observed motions of pulsars. However, even in the presence of parity-violating processes with anisotropic scattering amplitudes, no asymmetry is generated in thermal equilibrium. We explain why this no-go theorem stymies some of the proposed explanations for the pulsar “kick” velocities. CERN-T...

Chiral plasmons without magnetic field.

Plasmons, the collective oscillations of interacting electrons, possess emergent properties that dramatically alter the optical response of metals. We predict the existence of a new class of plasmons-chiral Berry plasmons (CBPs)-for a wide range of 2D metallic systems including gapped Dirac materials. As we show, in these materials the interplay between Berry curvature and electron-electron int...

Magnetic-Field-Induced Stabilization of Non-Equilibrium Superconductivity

The NEAR Magnetic Field Instrument

The primary objective of the Magnetic Field Instrument on the Near Earth Asteroid Rendezvous (NEAR) spacecraft is to search for and characterize the magnetic field of the asteroid Eros to better understand the origin and evolution of this planetary body. The instrument consists of a three-axis fluxgate magnetometer with a sensor mounted on the high-gain antenna feed structure of the NEAR spacec...
