Quantum Adiabatic Phases And Chiral Gauge Anomalies
The quantum adiabatic phase [1,2] has recently emerged as a universal element in the topological analysis of various quantum mechanical problems. It can be understood as an Ahoronov-Bohm effect on the parameter space of a quantum mechanical system and has seen numerous applications, notably to the analysis of corrections to semiclassical quantization [2,3,4], the statistics of quasiparticles such as vortices in two dimensional systems [6,6,7], adiabatic effective actions, the quantum Hall effect  and chiral anomalies in the Hamiltonian, Schrödinger picture of gauge theories . Furthermore, some of its predicted interference phenomena have recently found good agreement with experiment [10,11]. In this review we shall give a simple account of the origin of the quantum adiabatic phase, describe how the concept is used to construct adiabatic effective actions and discuss chiral gauge anomalies within this framework.
