Résumé |
Conformal field theory is playing an essential role in developing our understanding of entanglement in many-body systems and field theory. I will discuss how it allows one to access the entanglement spectrum, which is known to encode defining characteristics of the system, such as topological signatures. In order to study these spectra in-depth in the presence of symmetries, a refined notion, called symmetry-resolved entanglement, can be introduced. I will demonstrate the lessons this holds when the system’s symmetry is generated by a U(1) Kac-Moody algebras and the Virasoro algebra. |
