معرفی
Dr. Yang Xian is a Lecturer in Theoretical Physics at the School of Physics and Astronomy, The University of Manchester. His research focuses on quantum many-body theories and their applications in condensed matter physics, particularly in quantum spin lattices and strongly correlated boson and fermion systems. He is a member of the Theoretical Physics Group and has made significant contributions to the understanding of topological magnon insulators, quantum magnetism, and coupled-cluster methods.
Dr. Xian earned his BSc in Physics from Zhongshan University in Guangzhou, China, followed by a PhD from the School of Physics and Astronomy at the University of Minnesota, Minneapolis, USA. His academic journey has positioned him at the forefront of theoretical condensed matter physics research.
Dr. Xian's research primarily centers on quantum many-body theories applied to condensed matter systems. His work explores quantum spin lattices, topological magnon insulators, and strongly correlated electron systems. He has developed advanced microscopic techniques based on coupled-cluster methods for accurate calculations of ground state energy, order parameters, and other properties of Hamiltonian lattice systems. His current focus includes the unification of variational coupled-cluster method with Jastrow theory to address strongly correlated boson and fermion systems, with applications to quantum spin liquids and twisted bilayer graphene.
