Thermalization of neutrons at ultracold nanoparticles to the energy range of ultracold neutrons
V. V. Nesvizhevsky
Two hypothesizes concerning interaction of neutrons with nanoparticles and having applications in the physics of ultracold neutron (UCN) were recently considered in ref. [Physics o…
Constraints for quasi-elastic neutron reflections in the range dE~10^(-12)-10^(-9) eV
V. V. Nesvizhevsky
A restrictive constraint for any quasi-elastic process was obtained in the previously inaccessible energy range dE~10^(-12)-3x10^(-10) eV for reflections of ultracold neutrons from…
Bridge-mediated Donor-Acceptor Effective Coupling: Exact theoretical description
D. J. Bicout, F. Varchon, E. Kats
An exact expression of the bridge-mediated donor-acceptor effective coupling, is derived. For systems represented by a tight-binding Hamiltonian with nearest-neighbor interactions,…
Direct Observation of Quadrupolar Excitons in the Heavy-Fermion Superconductor PrOsSb
K. Kuwahara, K. Iwasa, M. Kohgi +8
We report inelastic neutron scattering experiments performed to investigate the low energy magnetic excitations on single crystals of the heavy-fermion superconductor PrOsSb$…
Valence-Bond Crystal, and Lattice Distortions in a Pyrochlore Antiferromagnet with Orbital Degeneracy
S. Di Matteo, G. Jackeli, N. B. Perkins
We discuss the ground state properties of a spin 1/2 magnetic ion with threefold orbital degeneracy on a highly frustrated pyrochlore lattice, like Ti ion in B-spin…
Molecular motions in lipid bilayers studied by the neutron backscattering technique
Maikel C. Rheinstädter, Tilo Seydel, Franz Demmel +1
We report a high energy-resolution neutron backscattering study to investigate slow motions on nanosecond time scales in highly oriented solid supported phospholipid bilayers of th…
