Fractionalized Fermionic Quantum Criticality
 
The concept and methodology of the renormalization group is a cornerstone in physics, with far-reaching implications for the study of quantum field theory and critical phenomena. Its impact on the field cannot be overstated. One important direction in the research of many-body quantum theory is the renormalization group study of the so-called tensor-network states. The ultimate goal is to provide a powerful tool for solving correlated quantum problems, such as the mechanism behind high-temperature superconductivity.
 
In this talk, Professor Xiang will delve into the physical background and fundamental ideas that underlie the development of this field. Additionally, he will discuss the latest progress and explore directions for future research. Through this exploration, Professor Xiang and his team hope to gain a deeper understanding of the renormalization group and its potential for further advancing our understanding of the complex phenomena that arise in quantum many-body systems.
