Phase transitions due to Euclidean gravity
Mustafa Saeed, Diya Batool, Muhammad Muzammil +1
We use Ising-like models to probe the thermal nature of Euclidean spacetime backgrounds. We determine which properties of the background -- curvature, the presence of a horizon, or…

Semiclassical Mixmaster Universe
Muhammad Muzammil, Viqar Husain
We present a semiclassical study of the Mixmaster cosmology minimally coupled to a massive scalar field in the Hamiltonian formalism, with focus on three distinct scenarios: the cl…

Semiclassical geometrodynamics of homogeneous cosmology
Viqar Husain, Muhammad Muzammil
We study the classical-quantum (CQ) hybrid dynamics of homogeneous cosmology from a Hamiltonian perspective where the classical gravitational phase space variables and matter state…
