演講題目: Fractionalization and emergent gauge fields in quantum many-body system-topological fracton orders

摘       要:  Quantum many-body systems are exotic phases of matter that many properties are distinct from their classical counterparts. One unique property is fractionalization, where the many-body interactions lead to excitations carrying fractional charges and anynoic statistics. In this talk, I will review the concept of the emergent gauge fields in these quantum many-body systems and demonstrate the fundamental excitations described by the lattice gauge theories. I will introduce a new topological “fracton” order in 3+1 dimensions that hosts immobile excitations.
