Black holes as gases of punctures with a chemical potential: Bose-Einstein condensation and logarithmic corrections to the entropy
Olivier Asin, Jibril Ben Achour, Marc Geiller +2
We study the thermodynamical properties of black holes when described as gases of indistinguishable punctures with a chemical potential. In this picture, which arises from loop qua…
Projective Loop Quantum Gravity I. State Space
Suzanne Lanéry, Thomas Thiemann
Instead of formulating the state space of a quantum field theory over one big Hilbert space, it has been proposed by Kijowski to describe quantum states as projective families of d…
Projective Limits of State Spaces II. Quantum Formalism
Suzanne Lanéry, Thomas Thiemann
In this series of papers, we investigate the projective framework initiated by Jerzy Kijowski and Andrzej Okołów, which describes the states of a quantum theory as projective famil…
Projective Limits of State Spaces I. Classical Formalism
Suzanne Lanéry, Thomas Thiemann
In this series of papers, we investigate the projective framework initiated by Jerzy Kijowski and Andrzej Okołów, which describes the states of a quantum (field) theory as projecti…
Maximum Tension: with and without a cosmological constant
John D. Barrow, G. W. Gibbons
We discuss various examples and ramifications of the conjecture that there exists a maximum force (or tension) in general relativistic systems. We contrast this situation with that…
Loop Quantum Cosmology with Complex Ashtekar Variables
Jibril Ben Achour, Julien Grain, Karim Noui
We construct and study Loop Quantum Cosmology (LQC) when the Barbero-Immirzi parameter takes the complex value . We refer to this new quantum cosmology as complex Loop Qua…
