Measuring chirality in NMR in the presence of a static electric field
The Journal of Chemical Physics, 2008The scalar Hamiltonian of nuclear spins in the presence of a static electric field supports chirality. However, the eigenvalues of the Hamiltonian are not chiral; hence, chirality is not manifested in the usual NMR experiment. In this work, we show that the magnetization response to certain radio frequency pulse sequences exhibits chirality as well as ...

The acceleration of a neutron in a static electric field
Physics Letters A, 2012Abstract We show that when a non-relativistic neutron travels in a static electric field, the acceleration vector operator is perpendicular to the velocity operator. Kinetic energy is conserved. A spin-dependent field term in the canonical momentum gives rise to a non-dispersive contribution to the quantum mechanical (Aharonov–Casher) phase.

Static Electric and Magnetic Fields in Matter
2019The effects of electric polarization and magnetization are studied. The electric displacement D and the auxiliary field H are defined, and their relationship with the densities of free charge and free current, respectively, is found.

MRI and Static Electric and Magnetic Fields
2012Static electric and magnetic fields are permanently present in the environment. Whereas the static electric field is associated with the presence of fixed electrical charges, the magnetic field is due to the physical movement of electrical charges. Unlike the other categories of fields covered in this work, static fields do not vary over time.

Photodetachment of H- in a static electric field
The European Physical Journal D, 2006We derive a formula using closed-orbit theory for the photodetachment cross-section of H- in the presence of a static electric field when there is an arbitrary angle theta(L) between the laser polarization direction and the static electric field. This formula generalizes the previous result for laser polarization parallel to the static electric field ...

Static electric and magnetic fields in matter
2018The electric and magnetic fields at an arbitrary point inside matter fluctuate rapidly both in space and time. It is therefore necessary, in the chapter’s introduction, tomake the important distinction between microscopic and macroscopic fields. It is assumed throughout that the electric dipole approximation is valid, and several important properties ...
