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

Berry’s phase for displaced Landau-He-McKellar-Wilkens states
TL;DR: Ribeiro et al. as mentioned in this paper used the Landau-He-McKellar-Wilkens quantization to obtain Abelian and non-Abelian Berry phases for the displaced states.

Berry phase and interference effects in three-level atoms
TL;DR: In this paper, a theoretical analysis of Berry's phases, which is based on the Cartan subalgebra, is given for three-level atomic systems, under the adiabatic approximation and is related to topological fiber bundle theories.

Manifestations of quantum holonomy in interferometry
TL;DR: In this article, it is shown that it is possible to associate nonequivalent holonomies to Abelian and non-Abelian geometric phases, referred to as quantum holonomic phases.

Non-cyclic geometric phase of nuclear quadrupole resonance signals of powdered samples.
TL;DR: It is shown that the geometric phase recorded for the signal from a powdered sample at Δω=0 can be different from zero and can oscillate upon changes in duration of the r.f. excitation pulse.

On the possibility of observing Berry phases during optical transitions in atoms placed in an external varying electric field
V.I. Matveev,M.M. Musakhanov +1 more
TL;DR: In this paper, the radiation spectrum for an atom placed in an external adiabatically varying electric field was derived for a single atom with Berry phases taken into account, and it was shown that the Berry phase is well observable during optical transitions in atoms placed in external varying electric fields.
