Geometric Phase of an Open System [PDF]
, 2009 Quantum state diffusion unraveling of the Linblad master equation is utilized to define a geometric phase of an open quantum system. It is then shown that such geometric phase is invariant under unitary symmetry transformations of the Linblad equation ...

Geometric phase, quantum measurements, and the de Broglie-Bohm model
, 1997 An approach to the measurement induced geometric phase based on the de Broglie-Bohm hidden-variable model is developed. The analysis involves an evolving geometric phase connecting the initial and final states of an individual experimental run.

Measurable quantum geometric phase from a rotating single spin [PDF]
, 2012 We demonstrate that the internal magnetic states of a single nitrogen-vacancy defect, within a rotating diamond crystal, acquire geometric phases. The geometric phase shift is manifest as a relative phase between components of a superposition of magnetic
