The adiabatic theorem and berry's phase
http://www.theorie.physik.uni-konstanz.de/burkard/sites/default/files/ts15/Berry-phase.pdf In physics, Berry connection and Berry curvature are related concepts which can be viewed, respectively, as a local gauge potential and gauge field associated with the Berry phase or geometric phase. The concept was first introduced by S. Pancharatnam as geometric phase and later elaborately explained and popularized by Michael Berry in a paper published in 1984 emphasizing how geometric phases provide a powerful unifying concept in several branches of c…
