Hidden quantum-informatic symmetries of quasi-de Sitter backgrounds
Suddhasattwa Brahma, Jaime Calderon-Figueroa, Xiancong Luo +1
We investigate how degeneracies in quasi-de Sitter backgrounds, in the sense of Wands' duality, are reflected in real-space quantum correlations of primordial perturbations. Using…
Multi-Matrix Quantum Mechanics, Collective Fields and Emergent Space
Yue Lei, Suddhasattwa Brahma, Robert Brandenberger
We study quantum mechanics of bosonic multi-matrix Lagragians in the collective field framework, with particular emphasis on three matrix models. We derive the effective Hamiltonia…
Thermal enhancement of inflationary magnetic fields
Arjun Berera, Suddhasattwa Brahma, Zizang Qiu +1
We investigate primordial magnetogenesis by assuming the gauge field is prepared in a thermal state during inflation rather than the standard Bunch-Davies vacuum. The temperature $…
Black holes in effective loop quantum gravity: Hawking radiation
Idrus Husin Belfaqih, Martin Bojowald, Suddhasattwa Brahma +1
Emergent modified gravity provides a covariant framework for holonomy effects in models of loop quantum gravity with consistent black hole solutions coupled to a scalar field. Seve…
