The emergence of photons, electrons, and gravitons from quantum qbit systems
Speaker(s): Xiao-Gang Wen
Abstract: We show that if a condensed matter system (a quantum qbit system) is in a string-net condensed state, then the low energy excitation in such a system can be gauge bosons (such as photons) and fermions (such as electrons). Such a system is actually the ether that we have been looking for 150 years. We will also discuss a quantum qbit system that may even give rise to emergent gravitons.
