Condensed Matter Theory Seminar: Ruihua Fan, Harvard University, “Entanglement Linear Response — Extracting the Quantum Hall Conductance from a Single Bulk Wavefunction and Beyond”

In this talk, I will introduce the so-called entanglement linear response, i.e., response under entanglement generated unitary dynamics. As an application, I will show how it can be applied to certain anomalies in 1D CFTs. Moreover, I will apply it to extract the quantum Hall conductance from a wavefunction and how it embraces a previous work on the chiral central charge. This gives new connection between entanglement, anomaly and topological response.
