Effects of underlying topology on quantum state discrimination
European Physical Journal C: Particles and FieldsIn this work, we show that quantum state discrimination can be modified due to a change in the underlying topology of a system. In particular, we explicitly demonstrate that the quantum state discrimination of systems with underlying discrete topology ...

(b,v)-type variables for black to white hole transitions in effective loop quantum gravity
Physics Letters B, 2021 Quantum gravity effects in effective models of loop quantum gravity, such as loop quantum cosmology, are encoded in the choice of so-called polymerisation schemes.

Universality in the Critical Behavior of the Correlation Functions in 2d Simplicial Gravity [PDF]
Acta Phys.Polon. 27 (1996) 1827-1834, 1996 The analogue of the loop-loop correlation function in 2d gravity for the planar connected $\phi^3$ diagrams is calculated. It is shown that although the discretized formulas are different the scaling limit is the same as for the loop-loop correlation function.

Cyclic universe from Loop Quantum Gravity
, 2015 We discuss how a cyclic model for the flat universe can be constructively derived from Loop Quantum Gravity. This model has a lower bounce, at small values of the scale factor, which shares many similarities with that of Loop Quantum Cosmology.

Constraining the loop quantum gravity parameter space from phenomenology
Physics Letters B, 2018 Development of quantum gravity theories rarely takes inputs from experimental physics. In this letter, we take a small step towards correcting this by establishing a paradigm for incorporating putative quantum corrections, arising from canonical quantum ...

Spin Foams and Canonical Quantization
Symmetry, Integrability and Geometry: Methods and Applications, 2012 This review is devoted to the analysis of the mutual consistency of the spin foam and canonical loop quantizations in three and four spacetime dimensions.

On the counting of black hole states in loop quantum gravity [PDF]
arXiv, 2004 We argue that counting black hole states in loop quantum gravity one should take into account only states with the minimal spin at the horizon.
