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.
متن کاملHypocoordinated solids in particulate media.
We propose a "phase diagram" for particulate systems with purely repulsive contact forces, such as granular media and colloids. We characterize two classes of behavior as a function of the input kinetic energy per degree of freedom T_{0} and packing fraction deviation from jamming onset Δϕ=ϕ-ϕ_{J} using simulations of frictionless disks. Isocoordinated solids (ICS) exist above jamming; they pos...
متن کاملNeutron Depolarization Studies of Pd-Ni-Fe-P alloy
Bulk metallic glasses based on the quaternary alloy Pd-Ni-Fe-P exhibit interesting phase behavior depending on temperature and applied magnetic field. Previous work has suggested that a range of magnetic phases including paramagnetic, superparamagnetic, ferromagnetic and spin glass can be observed in this system. We have applied one dimensional neutron depolarization to explore the correlation ...
متن کاملNeutron-Anti-Neutron Oscillation: Theory and Phenomenology
The discovery of neutrino masses has provided strong hints in favor of the possibility that B-L symmetry is an intimate feature of physics beyond the standard model. I discuss how important information about this symmetry as well as other scenarios for TeV scale new physics can be obtained from the baryon number violating process, n− n̄ oscillation. This article presents an overview of different...
متن کاملParticle-scale reversibility in athermal particulate media below jamming.
We perform numerical simulations of repulsive, frictionless athermal disks in two and three spatial dimensions undergoing cyclic quasistatic simple shear to investigate particle-scale reversible motion. We identify three classes of steady-state dynamics as a function of packing fraction φ and maximum strain amplitude per cycle γ(max). Point-reversible states, where particles do not collide and ...
