The adiabatic theorem is a concept in quantum mechanics. Its original form, due to Max Born and Vladimir Fock (1928), was stated as follows: A physical system remains in its instantaneous eigenstate if a given perturbation is acting on it slowly enough and if there is a gap between the eigenvalue and the rest of the Hamiltonian's spectrum. Webgiven by the adiabatic theorem can not be improved. 1 Introduction The adiabatic theorem [1] occupies one of the central places in nonrelativistic quantum mechanics because it allows one to find an approximate solution of the Schro¨dinger equa-tion for the Hamiltonian which varies slowly in time. It was proved for the first time

WebThe adiabatic theorem of Quantum Mechanics describes the long time behavior of the solutions of an initial value problem where the Hamiltonian generating the evolution depends slowly in time. Traditionally, the theorem is stated for Hamiltonians that have an eigenvalue which is separated by a gap from the rest of the spectrum.
