A problem related to an interesting Casimir configuration.
I have the following configuration , related to a modified Casimir experiment. We have two parallel metal plates and an orthogonal metal plate connecting the two parallel plates. Note that this is very close to the experimental setup of the original Casimir experiment, except for the orthogonal plate (connecting the two parallel plates at one end). I would like to know all the Casimir forces that exist in this configuration.
For clarification you can see the following picture
My naive intuition could be incorrect, but my impression is that the asymmetric radiation pressure due to quantum fluctuations would lead to the emergence of a certain force (parallel to the parallel plates), but I don't know if the QFT / QED calculations justify my intuition (where in fact these virtual particles are just an intuitive representation of links in Feynman diagrams, linked to terms in infinite perturbation series).
Heuristic derivation of the Casimir effect from Heisenberg Uncertainty Principle
Heuristic derivation of the Casimir effect from the Generalized Uncertainty Principle
Closely following the arguments in these two papers, that force mentioned above does indeed exist (for the three plate system mentioned above).
I hope somebody here can quickly settle this problem, so I don't spend a long time digging for an answer. Thanks.
