Fixed-point tensor network construction and generalized symmetry for conformal field theory

Abstract:The novel concept of entanglement renormalization and its corresponding tensor network renormalization technique have been highly successful in developing a controlled real space renormalization group (RG) scheme. In this talk, I will present an explicit analytical construction of the fixed point (FP) tensor for 2D rational CFT. We define it as a correlation function between the "bound...

Eigenvalue relation of the Heisenberg chain with various boundary conditions for the ground state

内容： We propose a new parametrization of the eigenvalues of transfer matrix in a quantum integrable model. Based on it, we obtain the exact solution of the system. By studying the distribution of ze...

Coherent control of single atom and atom array in strongly coupled cavity QED system

内容： 中性冷原子以及光子，因其具有良好的相干性，是量子操控和量子技术的重要系统。冷原子及其与光学腔的强耦合相互作用为人们提供了研究量子退相干，强耦合多体相互作用，展示若干量子效应的良好实验平台。本报告...
