Geometric phase
WebJan 23, 2024 · Different from the rotation-induced oppositely-spin-locked (OSL) geometric phase (φ L = −φ R), the ISL geometric phase is the same for left- and right-handed circularly polarization (LCP&RCP) states (φ L = φ R). Since LP waves can be decomposed into LCP and RCP waves, the same phase can also be imparted to LP waves, without … In classical and quantum mechanics, geometric phase is a phase difference acquired over the course of a cycle, when a system is subjected to cyclic adiabatic processes, which results from the geometrical properties of the parameter space of the Hamiltonian.
