B Boundary between a particle in two energy states

Hi I'm new to quantum mechanics, Looking for some help regarding a concept i am struggling to solve. I am curious if I had a cube of particles in a ground state and another cube with the same particle in a higher energy state.

If I placed one upon another, is there anything in quantum mechanics that would produce a barrier type effect.

Say if the top cube is in the ground state, Would the particles on the interface between each cube swap energy states and then swap straight back as the majority of the cube has a energy state weighted towards the ground state, some sort of sudo super positioning.

Kind regards,
Rick.

I think you need to be more specific about the physical scenario you have in mind. In general, a system of particles will reach a thermodynamic equilibrium, based on the overall energy and the allowable states for the system.
 

Thread 'Importance of Hanbury Brown and Twiss experiment'

I read Hanbury Brown and Twiss's experiment is using one beam but split into two to test their correlation. It said the traditional correlation test were using two beams........ This confused me, sorry. All the correlation tests I learnt such as Stern-Gerlash are using one beam? (Sorry if I am wrong) I was also told traditional interferometers are concerning about amplitude but Hanbury Brown and Twiss were concerning about intensity? Isn't the square of amplitude is the intensity? Please...

Thread 'Prof Mike Wiest's proposed link between quantum and consciousness'

I am not sure if this belongs in the biology section, but it appears more of a quantum physics question. Mike Wiest, Associate Professor of Neuroscience at Wellesley College in the US. In 2024 he published the results of an experiment on anaesthesia which purported to point to a role of quantum processes in consciousness; here is a popular exposition: https://neurosciencenews.com/quantum-process-consciousness-27624/ As my expertise in neuroscience doesn't reach up to an ant's ear...
