Berry Phase of a Resonant State
We derive closed analytical expressions for the complex Berry phase of an open quantum system in a state which is a superposition of resonant states and evolves irreversibly due to the spontaneous decay of the metastable states. The codimension of an accidental degeneracy of resonances and the geometry of the energy hypersurfaces close to a crossing of resonances differ significantly from those...
متن کاملBerry phase from a quantum Zeno effect
We exhibit a specific implementation of the creation of geometrical phase through the state-space evolution generated by the dynamic quantum Zeno effect. That is, a system is guided through a closed loop in Hilbert space by means a sequence of closely spaced projections leading to a phase difference with respect to the original state. Our goal is the proposal of a specific experimental setup in...
متن کاملQuantum mechanical histories and the Berry phase
We elaborate on the distinction between geometric and dynamical phase in quantum theory and we show that the former is intrinsically linked to the quantum mechanical probabilistic structure. In particular, we examine the appearance of the Berry phase in the consistent histories scheme and establish that it is the basic building block of the decoherence functional. These results are consequences...
متن کاملBerry Phase with Environment: Classical versus Quantum
We discuss the concept of the Berry phase in a dissipative system. We show that one can identify a Berry phase in a weakly-dissipative system and find the respective correction to this quantity, induced by the environment. This correction is expressed in terms of the symmetrized noise power and is therefore insensitive to the nature of the noise representing the environment, namely whether it i...
متن کاملModeling And Control Of Berry Phase In Quantum Dots
We study numerically the Berry phase in semiconductor quantum dots (QDs) that is induced by letting the dots to move adiabatically in a closed loop in the 2D plane along the circular trajectory. We show that the Berry phase is highly sensitive to the Rashba and Dresselhaus spin-orbit lengths. Based on the Finite Element Method, we solve the Schrödinger equation and investigate the evolution of ...
