Symmetry and Exact Solutions of General Spin-Boson Models

Published 23 Feb 2026 in quant-ph and math-ph | (2602.19747v1)

Abstract: Spin-boson models are the canonical benchmark for quantum dissipation. We show the symmetry structure of general spin-boson Hamiltonians and obtain their spectra explicitly by exploiting the symmetry. As an illustration of the general case, we numerically demonstrate the exact solution for the two-mode case.
