Superradiant Quantum Phase Transition for an Exactly Solvable Two-Qubit Spin-Boson Model
A spin-boson-like model with two interacting qubits is analysed. The model turns out to be exactly solvable since it is characterized by the exchange symmetry between the two spins. The explicit expressions of eigenstates and eigenenergies make it possible to analytically unveil the occurrence of fi...
