Quantum and classical areas of black hole thermodynamics
A. Ghosh, P. Mitra
Most calculations of black hole entropy in loop quantum gravity indicate a term proportional to the area eigenvalue A with a correction involving the logarithm of A. This violates…
Absence of log correction in entropy of large black holes
A. Ghosh, P. Mitra
Earlier calculations of black hole entropy in loop quantum gravity led to a dominant term proportional to the area, but there was a correction involving the logarithm of the area,…
Area law for black hole entropy in the SU(2) quantum geometry approach
P. Mitra
Black hole thermodynamics suggests that a black hole should have an entropy given by a quarter of the area of its horizon. Earlier calculations in U(1) loop quantum gravity have le…
Black hole entropy
P. Mitra
We review black hole entropy with special reference to euclidean quantum gravity, the brick wall approach and loop quantum gravity.
Fine-grained state counting for black holes in loop quantum gravity
A. Ghosh, P. Mitra
A state of a black hole in loop quantum gravity is given by a distribution of spins on punctures on the horizon. The distribution is of the Boltzmann type, with the area playing th…
Quasi-reversible Magnetoresistance in Exchange Spring Tunnel Junctions
M. Zhu, M. J. Wilson, P. Mitra +2
We report a large, quasi-reversible tunnel magnetoresistance in exchange-biased ferromagnetic semiconductor tunnel junctions wherein a soft ferromagnetic semiconductor (\gma) is ex…
