题目: Disorder-induced topological phase transitions in chiral
symmetric topological insulator
insulators with time reversal symmetry is well studied in recent years.
Besides, there exist many other topological insulators which were classified by
distinct symmetries. How to characterize effectively these topological
insulators by topological invariants and how disorder affects topological insulator
are important in some sense. In this talk, I first give an introduction about
chiral symmetric topological insulator and non-commutative winding number.
Then, the topological phase transitions due to disorder are illustrated in 1D
and 3D chiral topological insulators. Some intriguing critical phenomena
between topological phase transitions are presented.
