Title: Qubit Regularization: Large Charge CFTs and Asymptotic Freedom

Abstract: Qubit regularization is the idea to regulate a QFT on a lattice with a finite dimensional Hilbert space per site. This idea is important for studying QFTs on a quantum computer. It is well know that such an approach is viable for a variety …

Title: The OPE meets semiclassics

Abstract: Most of the predictions of the large charge expansion concern the spectrum of the theory and the expectation value of light operators between two heavy charged states in CFTs with internal symmetries. In this talk I will show that also the correlation functions of three large …

Title: Resurgence of the large-charge expansion

Abstract: In this talk I will discuss the d=3 Wilson-Fisher O(N) CFT in a large-charge sector, where also N is taken to be large. The large-charge expansion of critical exponents of the model turns out to be an asymptotic series with double factorial growth. Resurgent …

Title: Large Charge Sector of 3d Parity-Violating CFTs

Abstract: I will discuss 3d CFTs that become superfluids at finite density. When parity is not a symmetry, the Goldstone EFT contains a single 1-derivative term with quantized coefficient. This term forces the superfluid ground state to have vortices on the sphere, …
