From entropy to echoes: Counting the quasi-normal modes and the quantum limit of silence

We estimate the canonical entropy of a quantum black hole by counting its quasi-normal modes. We first show that the partition function of a classical black hole, evaluated by counting the quasi-normal modes with a thermodynamic Boltzmann weight, leads to a small entropy of order unity due to the sm...
