AbstractBy means of the Lie algebra SU(2), the investigation of the evolution behavior of two-level systems described by arbitrary time-dependent Hamiltonians is transformed into the study of a first-order differential equation. A general closed-form solution of the time-evolution operator is obtained, from which the results for any special case can be derived. This is illustrated by several simple examples, all of which may be useful for future studies on a variety of fields in quantum physics.
