Einstein and Jordan frame correspondence in quantum cosmology: Expansion-collapse duality
Dipayan Mukherjee, Harkirat Singh Sahota
The conformal correspondence between FLRW universes in the Einstein and Jordan frames allows for an expansion-collapse duality -- an always expanding Einstein frame universe can ha…

Bouncing and collapsing universes dual to late-time cosmological models
Dipayan Mukherjee, H. K. Jassal, Kinjalk Lochan
We use the Jordan frame-Einstein frame correspondence to explore dual universes with contrasting cosmological evolutions. We study the mapping between Einstein and Jordan frames wh…

Dual Theories of Quintessence : Expansion-Collapse Duality
Dipayan Mukherjee, H. K. Jassal, Kinjalk Lochan
The accelerated expansion of the universe demands presence of an exotic matter, namely the dark energy. Though the cosmological constant fits this role very well, a scalar field mi…
