Quantum out-of-equilibrium cosmology
European Physical Journal C: Particles and Fields, 2019 In this work, our prime focus is to study the one to one correspondence between the conduction phenomena in electrical wires with impurity and the scattering events responsible for particle production during stochastic inflation and reheating implemented

Universe, 2022 Time in quantum gravity is not a well-defined notion despite its central role in the very definition of dynamics. Using the formalism of quantum geometrodynamics, we briefly review the problem and illustrate it with two proposed solutions.

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War
Anthropology of Consciousness, EarlyView.ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

Switching Internal Times and a New Perspective on the `Wave Function of the Universe’
Universe, 2019 Despite its importance in general relativity, a quantum notion of general covariance has not yet been established in quantum gravity and cosmology, where, given the a priori absence of coordinates, it is necessary to replace classical frames with ...

Polymer Dynamics of Isotropic Universe in Ashtekar and in Volume Variables
Universe, 2022 We analyze the semiclassical and quantum polymer dynamics of the isotropic Universe in terms of both the standard Ashtekar-Barbero-Immirzi connection and its conjugate momentum and also of the new generalized coordinate conjugate to the Universe volume ...

Asia Pacific Viewpoint, EarlyView.ABSTRACT This research note advances the idea of a talanoa epistemology. Many readers will be familiar with talanoa as an Indigenous mode of communication practiced in the Pacific. Variations of talanoa have been applied in COP constellations, inter‐faith meetings, Pacific diplomacy, conflict resolution, and as a research method.

Classical and quantum cosmology of minimal massive bigravity
Physics Letters B, 2016 In a Friedmann–Robertson–Walker (FRW) space–time background we study the classical cosmological models in the context of recently proposed theory of nonlinear minimal massive bigravity.

Causal Loop Quantum Gravity and Cosmological Solutions
, 2004 We shall present here the causal interpretation of canonical quantum gravity in terms of new variables. Then we shall apply it to the minisuperspace of cosmology.

Reheating via gravitational particle production in simple models of quintessence or $\Lambda$CDM inflation [PDF]
, 2017 We have tested some simple $\Lambda$CDM (the same test is also valid for quintessence) inflation models, imposing that they match with the recent observational data provided by the BICEP and Planck's team and leading to a reheating temperature, which is ...
