Phase transition of fractional Chern insulators: QED3 and beyond
Speaker(s): Yin-Chen He
Abstract: Recent experiments in graphene heterostructures have observed Chern insulators - integer and fractional Quantum Hall states made possible by a periodic substrate potential. Here we study theoretically that the competition between different Chern insulators, which can be tuned by the amplitude of the... read more

Exotic emergent phenomena from many-body entanglement
Speaker(s): Yin-Chen He
Abstract: Many-body entanglement can lead to exotic phases of matter beyond conventional symmetry breaking paradigm. Those exotic phases may contain fractionalized quasiparticles and emergent gauge fields. In this talk,  I will focus on a wide class of long-range entangled phases—quantum spin liqui... read more

Spin liquids on kagome lattice and symmetry protected topological phase
Speaker(s): Yin-Chen He
Abstract: In my talk I will introduce the spin liquid phases that occur in kagome antiferromagnets, and discuss their physical origin that are closely related with the newly discovered symmetry protected topological phase (SPT). I will first present our numerical (DMRG) study on the kagome XXZ spin model that... read more
