How a nonzero geometric phase in a loop is used to generate artificial gauge potentials? If possible, also discuss how to generate the non-abelian artificial gauge potentials.
How can “quantum particles have positive masses, even though the classical waves travel at the speed of light”?
Clay Mathematics Institute writes about the Yang-Mills and mass gap problem on this page http://www.claymath.org/millennium/Yang-Mills_Theory/: The successful use of Yang-Mills theory to describe ...
Do you know why in the quantization of SU(2) Yang Mills Gauge Theory, it is always chosen the Weyl (temporal) gauge to derive the Hamiltonian? Is it possible to fix another gauge?
