Combination of both quantum field theory (QFT) and string theory in curvedbackgrounds in a consistent framework, the string analogue model, allows us toprovide a full picture of the Kerr-Newman black hole and its evaporation goingbeyond the current picture. We compute the quantum emission cross section ofstrings by a Kerr-Newmann black hole (KNbh). It shows the black hole emissionat the Hawking temperature T_{sem} in the early evaporation and the new stringemission featuring a Hagedorn transition into a string state of temperature T_s at the last stages. New bounds on the angular momentum J and charge Q emergein the quantum string regime. The last state of evaporation of a semiclassicalKNbh is a string state of temperature T_s, mass M_s, J = 0 = Q, decaying as aquantum string into all kinds of particles.(There is naturally, no loss ofinformation, (no paradox at all)). We compute the microscopic string entropyS_s(m, j) of mass m and spin mode j. (Besides the usual transition at T_s), wefind for high j, (extremal string states) a new phase transition at atemperature T_{sj} higher than T_s. We find a new formula for the Kerr blackhole entropy S_{sem}, as a function of the usual Bekenstein-Hawking entropy .For high angular momentum, (extremal J = GM^2/c), a gravitational phasetransition operates and the whole entropy S_{sem} is drastically different fromthe Bekenstein-Hawking entropy. This new extremal black hole transition occursat a temperature T_{sem J} higher than the Hawking temperature T_{sem}.Comment: New articl
