Description
This will be a blackboard talk consisting of a pedagogical overview of the so-called symmetry-resolved entanglement (SRE), which captures the refined structures of quantum entanglement in quantum systems with global symmetries. I will start with a short review of quantum entanglement in quantum many-body systems, followed by a brief description of an experiment that has motivated intensive studies of SRE in the past few years. I will then define the measures quantifying SRE, outline the computational strategies, and describe some characteristic properties of SRE measures. Time permitting, I will also briefly describe a computational framework outlined in arXiv:2412.14165, which is suitable to track the dynamical evolution of SRE and the full-counting statistics of symmetry charge distribution in symmetry-preserving out-of-equilibrium processes.
