SUMMARY

The discussion centers on the effects of the Hamiltonian preferred basis on decoherence in quantum systems. It clarifies that the preferred basis is determined by the choice of measurement device, which influences the observable being measured. The conversation highlights the implications of this choice on the behavior of electrons, specifically regarding their positioning in orbital bands. Understanding the preferred basis is crucial for evaluating probabilities from quantum states using Born's rule.

What would be the effects on the system for different values of the Hamiltonian preferred basis in Decoherence? Would it for example make the electrons higher in orbital or bands? Or what would be the exact effects?

What do you mean by "preferred basis"? You choose a basis by choosing a measurement device, because then you measure the corresponding observable, and that's why you evaluate the corresponding probabilities from the given state via Born's rule. That's all what's behind the term "a preferred basis", one sometimes read in texts on "interpretation".
