A consistent flow of entropy
Mohammad H Ansari
A common approach to evaluate entropy in quantum systems is to solve a master-Bloch equation to determine density matrix and substitute it in entropy definition. However, this meth…
Quantum amplification effect in a horizon fluctuations
Mohammad H. Ansari
The appearance of a few unevenly- spaced bright flashes of light on top of Hawking radiation is the sign of the amplification effect in black hole horizon fluctuations. Previous st…
Area, ladder symmetry, degeneracy and fluctuations of a horizon
Mohammad H. Ansari
Loop quantum gravity admits a kind of area quantization that is characterized by three quantum numbers. We show the complete spectrum of area is the union of equidistant subsets an…
Spectroscopy of a canonically quantized horizon
Mohammad H. Ansari
Deviations from Hawking's thermal black hole spectrum, observable for macroscopic black holes, are derived from a model of a quantum horizon in loop quantum gravity. These arise fr…
A statistical formalism of Causal Dynamical Triangulations
Mohammad H. Ansari, Fotini Markopoulou
We rewrite the 1+1 Causal Dynamical Triangulations model as a spin system and thus provide a new method of solution of the model.
Self-organized criticality in quantum gravity
Mohammad H. Ansari, Lee Smolin
We study a simple model of spin network evolution motivated by the hypothesis that the emergence of classical space-time from a discrete microscopic dynamics may be a self-organize…
