High-order quantum adiabatic approximation and Berry's phase factor

Chang-Pu Sun

Published Apr 7, 1988• 85 citations
Publisher

Abstract

In this paper high-order adiabatic approximate solutions of the Schrodinger equation for a quantum system with a slowly changing Hamiltonian are presented. The author not only obtains Berry's phase factor and strictly proves the quantum adiabatic theorem in the first-order approximation, but also discusses an observable effect of the second adiabatic approximation.

QUASI-ADIABATIC APPROXIMATION FOR THE SLOWLYCHANGING QUANTUM PROCCESS AND BERRY PHASE FACTOR

Chen Sun

By using group representation theory, th quasi-adiabatic approximation solution of the schrodinger equation of a quantum system with slowly-changing Hamiltonian are presented in this paper. We not only obtained the Berry phase factor and strictly proved the quantum adiabatic theorem as the zeroth-order approximation, but also studied the universal Berry phase factor and its geometrical interpretation when the adiabatic condition is violated. It is pointed out that this universal Berry phase factor has observable effects.

High-order adiabatic approximations related to non-Abelian Berry's phase factors and nuclear quadrupole resonance

Chang-Pu Sun

A high-order adiabatic-approximation method is proposed to study the time evolution of degenerate quantum-mechanical systems with slowly changing Hamiltonians. We not only discuss the quantum adiabatic theorem, induced gauge structure, and non-Abelian Berry's phase factors in the first-order approximation, but we also give nonadiabatic corrections for problems in the second-order approximation. With the nuclear quadrupole resonance as an explicit example, we analyze the above-mentioned questions in detail and point out the observable effects of non-Abelian Berry's phase factors for nonadiabatic transitions between two instantaneous states in an improvement of Tycko's experiment.

High-order quantum berry's adiabatic phase and its observable effect

Sun Changpu

New high-order adiabatic approximate method is proposed for the study of non-adiabatic evolution of a quantum system with slowly-changing Hamiltonian. The corresponding high-order Berry's adiabatic phases are used to describe the transition from a state to another, and their observable effects in quantum interference experiment are pointed out.

Evolution of systems with a slowly changing Hamiltonian

Zhaoyan Wu

A general method of solving Schr\"odinger equations for systems with a slowly (not necessarily extremely slowly) changing Hamiltonian is proposed. Its zeroth-order approximation gives the improved adiabatic theorem by Berry [Proc. R. Soc. London, Ser. A 392, 45 (1984)]. It shows how transitions between different energy levels occur when the Hamiltonian changes less slowly. Selection rules for such transitions are discussed.

Higher-order adiabatic approximations for classical evolution

Zhaoyan Wu

The higher-order adiabatic approximation method of solving the Schr\"odinger equation for slowly transported quantum systems, which contains Berry's improved adiabatic theorem as its zeroth-order step, is generalized to solve evolution equations for a wide class of slowly transported classical systems. It is shown how the adiabatic condition is broken and transitions between different modes take place. Selection rules for such transitions are shown to be a topological property of the evolution path in parameter space.

HIGH-ORDER ADIABATIC APPROXIMATIONS FOR EVOLUTION OF DEGENERATE QUANTUM MECHANICAL SYSTEM AND NON-ABELIAN INDUCED GAUGE STRUCTURE

Chen Sun

In this paper high-order adiabatic approximate method is proposed to study the evolution of degenerate quantum systums with slowly-changing parameters and varying symmetry. We not only prove the quantum adiabatic theorem for degenerate cases and discuss the corresponding non-abelian induced gauge structure, but also point out the non-adiabatic corrections resulting from higher-order approximations. With nuclear quadrupole resonance as an explicit example, we use this method to analyse observable effects of non-abelian Berry's phases in adiabatic and non-adiabatic experimental process.
