Journal ArticleDOI
Exact solvability of the quantum Rabi model using Bogoliubov operators
TL;DR: In this paper, Braak et al. showed that the two-photon Rabi model can be solved exactly by treating extended squeezed states on an equal footing, and the isolated Juddian solutions are also analytically obtained in terms of degeneracy.
Journal ArticleDOI
Numerically exact solution to the finite-size Dicke model
TL;DR: By using extended bosonic coherent states, a technique to solve the Dicke model exactly is proposed in the numerical sense as discussed by the authors, and the accessible system size is two orders of magnitude higher than that reported in the literature.
Journal ArticleDOI
Semi-classical and quantum Rabi models: in celebration of 80 years
Daniel Braak,Qing-Hu Chen,Murray T. Batchelor,Murray T. Batchelor,Enrique Solano,Enrique Solano +5 more
TL;DR: The special issue collection of articles on Semi-classical and quantum Rabi models was published in J. Phys. A: Mathematical and Theoretical to mark the 80th anniversary of the Rabi model.
Journal ArticleDOI
Two-photon Rabi model: analytic solutions and spectral collapse
TL;DR: In this paper, the singularity structure of the G-function allows to draw conclusions about the distribution of these eigenvalues along the real axis and derive the spectral collapse phenomenon at critical coupling, found numerically before.
Journal ArticleDOI
Entanglement dynamics of two independent Jaynes-Cummings atoms without the rotating-wave approximation
TL;DR: In this article, the authors studied the entanglement evolution of two independent Jaynes-Cummings atoms without the rotating-wave approximation (RWA) by a numerically exact approach.
