Modern computational and theoretical approaches are playing increasingly important roles in the advances of physics and quantum material research, particularly in quantum many-body systems, where strong correlations among multiple degrees of freedom, including electronic, spin, lattice, and orbital, have rendered conventional methods inadequate. In recent years, a new trend of research, combining modern computational methods, such as exact diagonalization, quantum Monte Carlo, tensor network, neural network and artificial intelligence, and modern theoretical approaches such as conformal field theory and bootstrap analysis as well as topological techniques, has emerged and enabled scientists to thoroughly and in an interdisciplinary manner investigate the highly entangled quantum phases of matter, 2D moire materials, light-matter interaction, quantum simulators and Rydberg atom arrays, etc.

In light of these rapid developments and their lack of systematic introduction and education to senior undergraduate and graduate students and researchers in the Hong Kong and GBA area, we would like to organize the Hong Kong Computational and Theoretical Physics Study Group 2023.

Based on our successful experience in 2019 (Hong Kong Computational Physics Study Group), the Study Group will carry out in an innovative format: with distinguished public lectures, insightful serminars and hands-on tutorials and flexible individual discussions among the leading expert and participants, from March to June 2023. The Study Group will provide complete coverage of modern computational and theoretical techniques and give in-depth understanding and first-hand experience to students and researchers, thus boosting the research activities and developments in quantum many-body systems in Hong Kong and the GBA. The distinguished speakers and lecturers are established and active researchers working in the very front of these fields, and the interactions and potential collaborations between them and participants are strongly encouraged.
