The Bose-Fermi Kondo model (BFKM) has a rich phase diagram which is sensitive to w À1 0 ðoÞ / joj 1À , the spectral density of the dissipative bosonic bath. Here, we show that the SUð2Þ BFKM is exactly solvable by the Bethe Ansatz method if the dissipative bosonic bath has a singular spectrum, corre
