Anti-Hermitian Hamiltonians in Quantum Mechanics and Open Systems
There seem to be two schools of thought regarding non-Hermitian Hamiltonians. This review by Roccati et al. is a good resource.
The first approach recognizes that such non-Hermitian Hamiltonians can ...

Anti-Hermitian Hamiltonians in Quantum Mechanics and Open Systems
I understand that this evolution is not unitary, but does this represent a physical process?
If the evolution is not unitary then it is not guaranteed to preserve probability.
But, if it is unitary ...

Decomposing density matrix on non-orthogonal and incomplete set of states
I think your expression is missing one $\alpha$, in order to preserve the normalization $\operatorname{tr}(\rho_s)=1$.
The decomposition that you are showing is a statistical mixture between two ...
