"SpletThe coefficients Hij are called the Hamiltonian matrix or, for short, just the Hamiltonian. (How Hamilton, who worked in the 1830s, got his name on a quantum mechanical matrix is a tale of history.) It would be much better called the energy matrix, for reasons that will become apparent as we work with it. " - Trace exp hamiltonian

SpletMany thermodynamic relations involve inequalities, with equality if a process does not involve dissipation. In this article we provide equalities in which the dissipative contribution is shown to involve the relative entropy (a.k.a. Kullback-Leibler divergence).

SpletPurity has nothing to do with the Hamiltonian. If you know the density matrix $\rho$ of your system, purity is just $\text{Tr}(\rho^2)$. The Hamiltonian will help you with the expected internal energy: $\text{Tr}(\rho H)$ but, again, the state has to be provided from elsewhere, not from the Hamiltonian.
