(2012).} \itemab Summary: We have shown the thermodynamic changes in a (2+1)-dimensional rotating black hole when it absorbs a particle. The microscopic changes that the black hole undergoes are interpreted using the AdS/CFT correspondence. Using the particle-absorption phenomenon, we formulate an irreducible mass and black hole entropy directly related to the particle momenta. We describe the black hole evolution that preserves the second law of thermodynamics. A number of microstates that evaluate the entropy are analyzed at each of the black hole evolution stages. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1088/0264-9381/29/17/175011} \end
