Geometric characteristics of quantum evolution: curvature and torsion
Published 23 Jun 2010 in quant-ph, math-ph, and math.MP | (1006.4447v3)
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.
