Interaction picture as any other operator. In particular, let and be the density matrices in the interaction picture and the Schrödinger picture respectively. If there is probability to be in the physical state |"ψ"〉, then Transforming the Schrödinger equation into the interaction picture gives which states that in the interaction picture, a quantum state is evolved by the interaction part of the Hamiltonian as expressed in the interaction picture. If the operator "A" is time-independent (i.e., does not have "explicit time dependence"; see above), then the corresponding time evolution for "A"("t") is given by In the interaction picture the operators evolve in
Minimum Wage in Germany Minimum Wage in Germany Germany’s minimum wage legislation - "Gesetz zur Regelung eines allgemeinen Mindestlohns" - was introduced, on January 1, 2014, by Merkel’s third cabinet, composed of a coalition between the SPD – the social democratic party - and the CDU – the conservative party. The implementation of a minimum wage was the SPD’s main request during the coalition’s negotiations. Indeed, it was its central electoral promise during the 2013 federal elections’ campaign, to replace negotiated wages within branches that were previously set below the current minimum wage, Initially, the minimum wage was set to 8.50€. Its amount is
