Thermodynamics in Loop Quantum Cosmology
Advances in High Energy Physics, 2009 Loop quantum cosmology (LQC) is very powerful to deal with the behavior of early universe. Moreover, the effective loop quantum cosmology gives a successful description of the universe in the semiclassical region.

Higher dimensional Loop Quantum Cosmology [PDF]
, 2015 Loop quantum cosmology(LQC) is the symmetric model of loop quantum gravity. In this paper, we generalize the structure of loop quantum cosmology to the theories with arbitrary spacetime dimensions.

Quantum Cosmology from Group Field Theory Condensates: a Review [PDF]
, 2016 We give, in some detail, a critical overview over recent work towards deriving a cosmological phenomenology from the fundamental quantum dynamics of group field the- ory (GFT), based on the picture of a macroscopic universe as a \condensate" of a large ...

Hořava-Lifshitz Scalar Field Cosmology: Classical and Quantum Viewpoints
Advances in High Energy Physics, 2021 In this paper, we study a projectable Hořava-Lifshitz cosmology without the detailed balance condition minimally coupled to a nonlinear self-coupling scalar field.

Quantum Cosmology of f(R, T) gravity [PDF]
Gravity, 2016 Modified gravity theories have the potential of explaining the recent acceleration of the Universe without resorting to the mysterious concept of dark energy. In particular, it has been pointed out that matter–geometry coupling may be responsible for the

Isotropic Loop Quantum Cosmology [PDF]
, 2002 Isotropic models in loop quantum cosmology allow explicit calculations, thanks largely to a completely known volume spectrum, which is exploited in order to write down the evolution equation in a discrete internal time.

Effective loop quantum cosmology as a higher-derivative scalar-tensor theory [PDF]
, 2017 Recently, Chamseddine and Mukhanov introduced a higher-derivative scalar-tensor theory which leads to a modified Friedmann equation allowing for bouncing solutions.

No rescue for the no boundary proposal: Pointers to the future of quantum cosmology [PDF]
, 2017 In recent work, we introduced Picard-Lefschetz theory as a tool for defining the Lorentzian path integral for quantum gravity in a systematic semiclassical expansion. This formulation avoids several pitfalls occurring in the Euclidean approach.
