Hong Kong Computational Physics Study Group



Computational approaches are playing increasingly important role in the advances of condensed matter physics and quantum material research, in particular, in quantum many-body systems, where strong correlations among multiple degrees of freedom including electronic, spin, lattice and orbital, have rendered conventional analytic and perturbative methods inadequate. On the other hand, modern computational approaches, such as exact diagonalization, quantum Monte Carlo, density matrix renormalization group, tensor network renormalization group and neural network and artificial intelligence, are inherently non-perturbative and unbiased, and could, in principle, tackle quantum many-body systems in controlled manner.
In light of the rapid developments in computational approaches, and the lack of their systematically introduction and education to senior undergraduate and graduate students and junior researchers in the Hong Kong area, we would like to organize the Hong Kong Computational Physics Study Group. The form of the study group is flexible, on average, one or two seminar talks during the week and one hands-on tutorial during the weekend per month from September to November 2019.
The purpose of the study group is to provide a full coverage of modern computational techniques to give in-depth understanding and first-hand experience to students and junior researchers, and subsequently boost the research activities and developments of these computational approaches in quantum many- body systems in Hong Kong area. The selected lecturers are active researchers working in the very front of these fields, and the interactions and potential collaborations between the lecturers and participants are strongly encouraged.
