Abstract: Topological phases of matter are beyond the conventional Landau symmetry breaking paradigm. The presentation begins with the discussion of various signatures that detect these phases in different scenarios. These signatures being inconsistent across different scenarios, and with the notion of mixed topological states remaining ambiguous, an operational definition based on topological error correction is introduced. Motivated by several nonequilibrium phenomena, various open quantum setups that host topological phases are introduced while effectively detecting the criticalities using the operational definition. Further, the above definition is extended to the class of symmetry protected topological phases thereby establishing the criticalities in the variants of Su-Schrieffer-Heeger (SSH) models. Finally, to experimentally realize some of the above physics, optimal techniques to detect and manipulate polar molecules using atoms are presented that further aid in preparing the desired quantum many-body states.
