Geometric vector potentials from nonadiabatic spin dynamics
(American Physical Society, 2017-07-27)
We propose a theoretical framework that captures the geometric vector potential emerging from the nonadiabatic spin dynamics of itinerant carriers subject to arbitrary magnetic textures. Our approach results in a series ...

Effective geometric phases and topological transitions in SO(3) and SU(2) rotations
(IOP Publishing, 2016-03-24)
We address the development of geometric phases in classical and quantum magnetic moments (spin-1/2) precessing in an external magnetic field. We show that nonadiabatic dynamics lead to a topological phase transition ...

Spin resonance under topological driving fields
(IOP Publishing, 2017-06)
We study the dynamics of a localized spin-1/2 driven by a time-periodic magnetic field that undergoes a topological transition. Despite the strongly non-adiabatic effects dominating the spin dynamics, we find that the ...

Geometry-assisted topological transitions in spin interferometry
(American Physical Society, 2019)
We identify a series of topological transitions occurring in electronic spin transport when manipulating spin-guiding fields controlled by the geometric shape of mesoscopic interferometers. They manifest as distinct ...
