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 a suitable minimum wage amount. The first minimum wage adjustment was made in June 2016, and was followed two years later by another adjustment, in June 2018, that rose the minimum wage to 9.19€. The minimum wage was one of the most controversial topics during the 2013 legislative election campaign. While the social democratic party - SPD, the green party - die Grünen and the left-wing party - die Linke, were in favor of a general minimum wage, the liberal party – FDP, and the conservative party – CDU, remained skeptical Leading economic research institutions, such as the CESifo Group
