Anti-Hermitian Hamiltonians in Quantum Mechanics and Open Systems
Question: Can the presence of the anti-Hermitian term in Eq. 2 and Eq. 4 be justified or intuitively explained?
It seems that you proposed a mathematical model and is asking for a physical motivation,...

Time evolution of a tripartite quantum state
If you have a tripartite system and you do want to compute it's evolution, you need to write the global Unitarty Operator, evolve the global system and get the informations of some subsystem, if you ...

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 ...

Is there a no-cloning theorem for open quantum dynamics?
A channel $\Phi$ allowing to "clone" any input state would mean $\Phi(\rho)=\rho\otimes\rho$ for all states $\rho$.
Any channel $\Phi$ sending states in $\mathbb{C}^n$ to states in $\mathbb{...
