The study of phases of matter is a central theme in physics, and has been evolving in parallel with our improved understanding, via new concepts and methods, of many-body systems. In the past decade, the discipline has seen spectacular progress in the research of topological states, phases of matter that are beyond the Landau-Ginzburg-Wilson symmetry-breaking paradigm, but characterized by new types of global quantum numbers. Topological states host many a fascinating phenomenon such as robust edge states and fractional excitations. The exotic material properties make topological states an ideal platform for quantum computation and other technical applications. In the last several years, there has been a surge of new ideas and methods in theories for these states, and experimental discoveries of topological states of matter have also made great impact. The purpose of this Conference is to bring together leading experts to share their exciting discoveries and insights in this vigorous field, providing a venue for discussion and collaboration. 

The main topics of this Conference include (i) topological classification of strongly interacting systems, (ii) topological phase transitions and (iii) experimental realization of topological orders. Topic-(i) consists of the new developments in the classification of symmetry protected topological states and symmetry enriched topological orders with local and spatial symmetries; topic-(ii) encompasses the analytical and numerical studies of quantum phase transitions between distinct topological states, of phase transitions featuring deconfined quantum criticality, and the development in 2+1d duality that unifies certain phase transitions; and topic-(iii) involves experimental characterization of topological orders such as spin liquid and spin ice candidates.
