Symmetry and entropy of black hole horizons
Olaf Dreyer, Fotini Markopoulou, Lee Smolin
We argue, using methods taken from the theory of noiseless subsystems in quantum information theory, that the quantum states associated with a Schwarzchild black hole live in the r…

Background Independent Quantum Field Theory and the Cosmological Constant Problem
Olaf Dreyer
We introduce the notion of background independent quantum field theory. The distinguishing feature of this theory is that the dynamics can be formulated without recourse to a backg…

Black hole entropy calculations based on symmetries
Olaf Dreyer, Amit Ghosh, Jacek Wisniewski
Symmetry based approaches to the black hole entropy problem have a number of attractive features; in particular they are very general and do not depend on the details of the quanti…
