Entanglement Spectra and Operator content of (Boundary) CFTs

It is well known that the entanglement entropies of intervals in systems described by a CFT exhibit a logarithmic scaling with block size which is parametrized by the central charge of the CFT.
In this talk I will provide strong numerical evidence that the entanglement spectrum, ie the logarithm of the eigenvalues, contains even more information in the form of conformal towers, therefore allowing the analysis of the operator content of a CFT by simple inspection of density matrix spectra. I will show a few applications and also discuss on the differences in operator content of finite-size versus infinite system DMGR/MPS approaches.
