Supperconductivity in t1-t2-J1-J2 model on Honeycomb lattice
Speaker(s): Xiao-Gang Wen
Abstract: We studied t1-t2-J1-J2 model on Honeycomb lattice at finite doping. We find that when t_1 is very small, the t1-t2-J1-J2 model on Honeycomb lattice may be in a supperconducting phase. Such a supperconducting phase is not driven by the pairing, but by entanglement.

Local unitary transformation, long-range quantum entanglement, wave function renormalization, and topological order
Speaker(s): Xiao-Gang Wen
Abstract: Adiabatic evolutions connect two gapped quantum states in the same phase. We argue that the adiabatic evolutions are closely related to local unitary transformations which define a equivalence relation. So the equivalence classes of the local unitary transformations are the universality classes that... read more

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. W... read more
