... One could begin a study like the present one by simply postulating that our universe is four-dimensional. There are ample reasons for doing this. Experience, observation and experiment all point to the fact that we inhabit a four-dimensional universe. Another approach would be to show that four-dime ...

Inner and outer edge states in graphene rings: A numerical
... E = 0兲 of the quantum ring spectrum here is completely different than in the case of zigzag edges 共compare with Fig. 3兲. There are still edge-states subbands defined, each one containing six energy levels, however the difference is that there is now a wide subband around the Dirac point. An interest ...
