○ Title: topological phase transitions in Kitaev quantum spin liquids.

○ Abstract: Strongly correlated systems may host unconventional phases, characterized by emergence of non-locality. Kitaev quantum spin liquid (KQSL) is one of the most well known examples, and the emergent non-locality is encoded in fractionalized excitations of Majorana fermions. Evidence of KQSLs has been reported in various experiments including specific heat, NMR, and thermal Hall experiments. In this talk, we discuss properties of topological phase transitions in KQSLs and propose a way to identify a non-abelian KQSL by using magnetic-field responses.
