报告摘要
Quantum spin liquid state can be faithfully represented and efficiently characterized within the symmetric Projected Entangled Pair State (PEPS) framework. A prototypical example with SU(2) spin-1/2 on every lattice site is the nearest neighbor resonating valence bond (RVB) state, which has been thoroughly studied on various lattices with PEPS. Here I will show, through suitable deformation of the local tensor of NN RVB state on square lattice, we can introduce longer range singlets into the wave function and drive the state into a topological Z2 phase. This approach turns out to be very general. And I will also present our recent results about SU(3) chiral spin liquid using this approach.
个人简历
Dr.Chen got his bachelor degree in Lanzhou University majored in theoretical physics in 2011, and then did his PhD in physics at Tsinghua University from 2011 to 2017. After PhD, he moved to Toulouse, France, working on tensor network methods for quantum many-body physics. After a two-year postdoc in Toulouse, he moved to Max-Planck-Institue of Quantum Optics in Garching, Germany, continue his research in tensor networks. His research interest includes tensor networks, topological phase of matter, and quantum magnetism.
