Cosmological models with Bounce scenario in f(Q,C)-gravity
Bhaswati Mandal, B. C. Paul
We present a bounce universe in modified gravity considering linear as well as exponential form of gravity. Bounce cosmological models are introduced to remove the singula…

Can spacetime torsion source an extremely red-tilted cosmological GW background?
Arko Bhaumik, Bhaswati Mandal, Soumitra SenGupta
In the presence of spacetime torsion, any generic model of gravity is conformally dual to a scalar-tensor theory augmented with a second rank antisymmetric massless degree o…
