A morphism between two mathematical objects of the same type (e.g. groups, algebras, representations, categories, etc.), which preserves the defining structures of the objects, is one of the most important notions in mathematics. However, how to define such a morphism between two QFT’s (or quantum phases) had never been considered in physics until arXiv:1502.01690. In this talk, I will give a review of this notion and discuss its applications in the study of topological orders and more general quantum liquids. I will also clarify its relation with “topological symmetry” or “SymTFT”.

Quantum simulation of High Energy Physics (HEP) has seen remarkable growth in recent years. Nevertheless, there is a continuous need for advancements in the overall simulation framework. In my talk, I will first motivate the critical need for quantum computing in HEP and discuss recent developments.

Over the past few years, synthetic dimensions in photonics have been rapidly developing and generating significant interest. By utilizing different degrees of freedom of light, synthetic dimensions can be constructed. This seminar will focus on the creation of a synthetic frequency dimension in dynamically modulated ring resonator systems.
