1. The problem statement, all variables and given/known data
Hi
The density matrix evolves as
[tex]
\dot \rho = -\frac{i}{\hbar}[H,\rho]
[/tex]
but is this equation written in the Schrödinger or Heisenberg picture? I'm not entirely sure how to figure this out. In my book it just mentions the equation, not how it is derived (which may have given a hint...)
