Journal for the Theory of Social Behaviour, Volume 55, Issue 3, September 2025.ABSTRACT This article introduces immanent idealism as an alternative path in social ontology and theory. It argues for a distinction between three basic ontological dimensions, the ideational, the institutional and the structural. This approach highlights the cognitional priority of worldviews as the core element of the ideational dimension, and it ...

Dynamical behavior of interacting dark energy in loop quantum cosmology
, 2010 The dynamical behaviors of interacting dark energy in loop quantum cosmology are discussed in this paper. Based on defining three dimensionless variables, we simplify the equations of the fixed points.

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Restrictions on curved cosmologies in modified gravity from metric considerations
Physics Letters B, 2015 This study uses very simple symmetry and consistency considerations to put constraints on possible Friedmann equations for modified gravity models in curved spaces. As an example, it is applied to loop quantum cosmology.

Universe, 2023 In recent decades, there has been growing interest in the quantization of black holes using techniques developed in loop quantum cosmology. Due to the quantum geometry effect, the resulting quantum-corrected black hole provides non-singular models.

Bounce Loop Quantum Cosmology Corrected Gauss-Bonnet Gravity
, 2015 We develop a Gauss-Bonnet extension of Loop Quantum Cosmology, by introducing holonomy corrections in modified $F(\mathcal{G})$ theories of gravity.

Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

New Hamiltonian constraint operator for loop quantum gravity
Physics Letters B, 2015 A new symmetric Hamiltonian constraint operator is proposed for loop quantum gravity, which is well defined in the Hilbert space of diffeomorphism invariant states up to non-planar vertices with valence higher than three. It inherits the advantage of the

Nonlinear (loop) quantum cosmology
Physical Review D, 2012 Inhomogeneous quantum cosmology is modeled as a dynamical system of discrete patches, whose interacting many-body equations can be mapped to a non-linear minisuperspace equation by methods analogous to Bose-Einstein condensation. Complicated gravitational dynamics can therefore be described by more-manageable equations for finitely many degrees of ...
