Spin-1/2 geometric phase driven by decohering quantum fields
A. Carollo, I. Fuentes-Guridi, M. Franca Santos +1
We calculate the geometric phase of a spin-1/2 system driven by a one and two mode quantum field subject to decoherence. Using the quantum jump approach, we show that the correctio…

Geometric phase in open systems
A. Carollo, I. Fuentes-Guridi, M. Franca Santos +1
We calculate the geometric phase associated to the evolution of a system subjected to decoherence through a quantum-jump approach. The method is general and can be applied to many…
