WebDec 21, 2007 · Geometric phases are closely linked to the classical concept of parallel transport of a vector on a curved surface. Consider, for example, a tangent vector v on the surface of a sphere being transported from the sphere's north pole around the path P shown in Fig. 1A, with v pointing south at all times. The final state of the vector v f is rotated with … WebJun 3, 2024 · Furthermore, just like the adiabatic evolution of quantum states that is known to induce the Berry phase, sequential weak measurements may lead to path-dependent geometric phases. Here we measure the geometric phases induced by sequences of weak measurements and demonstrate a topological transition in the geometric phase …

WebConical intersections (CIs) are diabolical points in the potential energy surfaces generally caused by point-wise degeneracy of different electronic states, and give rise to the geometric phases (GPs) of molecular wave functions. Here we theoretically propose and demonstrate that the transient redistribution of ultrafast electronic coherence in … WebNov 26, 1992 · Abstract. When a quantum system evolves so that it returns to its initial physical state, it acquires a 'memory' of this motion in the form of a geometric phase in …
