Ultracold neutron depolarization in magnetic bottles

Gravitationally enhanced depolarization of ultracold neutrons in magnetic-field gradients

Trapped ultracold neutrons (UCNs) have for many years been the mainstay of experiments to search for the electric dipole moment (EDM) of the neutron, a critical parameter in constraining scenarios of new physics beyond the Standard Model. Because their energies are so low, UCNs preferentially populate the lower region of their physical enclosure and do not sample uniformly the ambient magnetic ...

Neutron Depolarization in Superconductors

The dependences of neutron depolarization on applied magnetic field are deduced along trie magnetization hysteresis loop in terms of the Beau mortel of the critical state. The depolarization in uniaxial superconductors with the reversible magnetization, mcluding uniaxial magnetic superconductors,is also considered. A strong depolarization is expected ifthe neutrons travel along the vortex fines.

Different‎ Magnetic Field ‎Distributions‎ in Deformed Neutron Stars‎

‎In this work, we review the formalism which would allow us to model magnetically deformed neutron stars. We study the effect of different magnetic field configurations on the equation of state (EoS) and ‎the ‎structure of such stars. ‎For this aim‎, the EoS of magnetars is acquired by using the lowest order constraint variational (LOCV) method ‎‎and ‎employing‎ the AV18 potential‎.‎...
