报告摘要:

The celebrated Dirac equation is not only the foundation of quantum field theory, but also the parent model of many
lateradvances inphysics. One of  the key notion derived from Dirac equation is the band topology for electrons in various
condensed matters. Recently this notion has been extended to bosonic systems, such as in photonics. I will briefly
introduce the background, fundamental challenges and recent advances in the search of photonic topological materials.
Band degeneracy and topology enrichedby both point-group and nonsymmorphic symmetries in all dielectric photonic
crystals are emphasized. Microscopic theory on the spin-orbit coupling, angular-momentum---wavevector locking are
discussed in details.
