Quantum Invariant Theory and Non-Adiabatic Non-Abelian Phase Factor
Jian Bo Fu, Xin‐Hua Li, Gao Xiaochun +1 more
An alternative formulation is proposed for the calculation of the non-adiabatic non-Abelian connection and phase factor by making use of the invariant theory and invariant-related unitary transformation method. In order to illustrate the formulation, we study the non-adiabatic non-Abelian phase associated with the motion of a charged particle in a time-dependent magnetic field (the time-dependent Landau level problem).
