Geometric characteristics of quantum evolution: curvature and torsion
arXiv:1006.4447 · doi:10.5488/CMP.20.13003
Abstract
We study characteristics of quantum evolution which can be called curvature and torsion. The curvature shows a deviation of the state vector in quantum evolution from the geodesic line. The torsion shows a deviation of state vector from the plane of evolution (a two-dimensional subspace) at a given time.
