Adiabatic rotational splittings and Berry's phase in nuclear quadrupole resonance.
TLDR
Sample rotation is shown to induce frequency splittings in nuclear-quadrupole-resonance spectra, interpreted both as a manifestation of Berry's phase and as a result of a fictitious magnetic field, associated with a rotating-frame transformation.Abstract:
Sample rotation is shown to induce frequency splittings in nuclear-quadrupole-resonance spectra. The splittings are interpreted both as a manifestation of Berry's phase, associated with an adiabatically changing Hamiltonian, and as a result of a fictitious magnetic field, associated with a rotating-frame transformation. Real and fictitious fields are contrasted. Related effects are predicted in other magnetic resonance experiments that involve sample rotation.read more

Quantum dynamics of magnetic and electric dipoles and the geometric phase
TL;DR: In this paper, the authors studied the quantum dynamics of a neutral particle that posseses permanent magnetic and electric dipole moments in the presence of an electromagnetic field and demonstrated the appearance of a quantum phase that combines the Aharonov-Casher effect and the He-Mckellar-Wilkens effect.

TL;DR: The multiple-quantum CP approach is shown to be beneficial for improving the sensitivity of CP-MQMAS experiments and for detecting dipolar correlations.

TL;DR: In this article, the authors performed an interference experiment using polarized neutrons which clearly demarcates the separate contributions of the dynamical and geometric phases to the total phase acquired during an evolution of a quantal system has two components: the usual dynamical phase, the integrated expectation value of the Hamiltonian, and a geometric phase which depends only on the geometry of the curve traced in ray space.

Third-order effect in solid-state NMR of quadrupolar nuclei
TL;DR: In this article, the theory and experimental observation of the third-order effect in solid-state NMR of quadrupolar nuclei are presented. But the third order effect consists of spherical harmonic terms up to rank l = 6 and shifts NMR frequencies between two spin states that are not symmetric such as satellite transitions.
