In that model, the energy of monochromatic electromagnetic radiation in a cubic cavity is $E=(d/4)\hbar ω$ where $d$ is a topological index equal to the degree of a map between two orbifolds.17 pages, no figures, to be published in Physics Letters AQuantum PhysicsInterplay of topology and quantization: topological energy quantization in a cavitytext
