Extension of Loop Quantum Gravity to Metric Theories beyond General Relativity
Yongge Ma
The successful background-independent quantization of Loop Quantum Gravity relies on the key observation that classical General Relativity can be cast into the connection-dynamical…
Adiabatic and non-adiabatic perturbations for loop quantum cosmology
Yu Li, Jian-Yang Zhu
We generalize the perturbations theory of loop quantum cosmology to a hydrodynamical form and define an effective curvature perturbation on an uniform density hypersurfaces .…
Loop Quantum Brans-Dicke Theory
Xiangdong Zhang, Yongge Ma
The loop quantization of Brans-Dicke theory (with coupling parameter ) is studied. In the geometry-dynamical formalism, the canonical structure and constraint algebra of…
Coherent State Functional Integrals in Quantum Cosmology
Li Qin, Yongge Ma
Coherent state functional integrals for the minisuperspace models of quantum cosmology are studied. By the well-established canonical theories, the transition amplitudes in the pat…
Introduction to Loop Quantum Cosmology
Kinjal Banerjee, Gianluca Calcagni, Mercedes Martín-Benito
This is an introduction to loop quantum cosmology (LQC) reviewing mini- and midisuperspace models as well as homogeneous and inhomogeneous effective dynamics.
A general maximum entropy principle for self-gravitating perfect fluid
Sijie Gao
We consider a self-gravitating system consisting of perfect fluid with spherical symmetry. Using the general expression of entropy density, we extremize the total entropy under…
