Vulnerability of f(Q) gravity theory and a possible resolution
Dalia Saha, Abhik Kumar Sanyal
Both the generalized teleparallel theories of gravity suffer from some serious problems. The strong coupling issue appearing as a consequence of extra degrees of freedom in the `ge…
Phase space structure of symmetric teleparallel theory of gravity
Dalia Saha, Abhik Kumar Sanyal
The `Generalized Symmetric Teleparallel Gravity' (GSTG) does not admit diffeomorphic invariance, since the auxiliary field as well as the shift vector act as non-propagating dynami…
Issue of Branched Hamiltonian, Inflation and indispensability of scalar field in generalized Teleparallel theories
Dalia Saha, Jyoti Prasad Saha, Abhik kumar sanyal
Generalized Teleparallel gravity theories were proposed as alternatives to the dark energy and modified theories of gravity. However, minimal generalization of TEGR and STEGR lead…
Reconstructing modified and alternative theories of gravity
Dalia Saha, Manas Chakrabortty, Abhik Kumar Sanyal
A viable radiation dominated era in the early universe is best described by the standard (FLRW) model of cosmology. In this short review, we demonstrate reconstruction of the forms…
Inflation and cosmological evolution with gravity theory
Dalia Saha, Jyoti Prasad Saha, Abhik Kumar Sanyal
In the last decade Planck PR4 data together with ground-based experimental data such as, BK18, BAO and CMB lensing, tightened constraint of the tensor to scalar ratio, starting for…
A viable form of the metric Teleparallel F(T) theory of gravity
Manas Chakrabortty, Nayem Sk, Abhik Kumar Sanyal
Unlike F(R) gravity, pure metric F(T) gravity in the vacuum dominated era, ends up with an imaginary action and is therefore not feasible. This eerie situation may only be circumve…
