On the generators of quantum dynamical semigroups
Abstract
The notion of a quantum dynamical semigroup is defined using the concept of a completely positive map. An explicit form of a bounded generator of such a semigroup on B(ℋ) is derived. This is a quantum analogue of the LévyKhinchin formula. As a result the general form of a large class of Markovian quantummechanical master equations is obtained.
