spelling Comment on 'Revisiting the phase transitions of the Dicke model'Corps, Á.L.Relaño, ArmandoQuantum PhysicsQuantum PhysicsPhysics - Statistical MechanicsComment; 5 pages, 3 figures.In the work of Das and Sharma [Phys. Rev. A 105, 033716 (2022)] the phase transitions of the Dicke model are studied. Its main result is that, besides the well-known quantum phase transition, excited-state quantum phase transition and thermal phase transition exhibited by the model, there exists an upper bound energy, $E_{*}$, beyond which the model ceases to exhibit quantum chaotic behavior and the structure of the eigenfunctions changes. Based on this finding, a number of well-established results about the Dicke model are called into question. We argue that this result and all its consequences are spurious numerical effects resulting from an improper truncation of the infinite-dimensional Hilbert space necessary for numerical diagonalization.This work has been supported by the Spanish Grant No. PGC-2018-094180-B-I00 funded by Ministerio de Ciencia e Innovación/Agencia Estatal de Investigación MCIN/AEI/10.13039/501100011033 and FEDER “A way of making Europe.” A.L.C. acknowledges financial support from “la Caixa” Foundation (ID 100010434) through the fellowship LCF/BQ/DR21/11880024.Peer reviewedAmerican Physical SocietyMinisterio de Ciencia e Innovación (España)Fundación la CaixaCorps, Á.L.
