Swampland, Axions and Minimal Warm Inflation
Suratna Das, Gaurav Goswami, Chethan Krishnan
Warm inflation has been noted previously as a possible way to implement inflationary models compatible with the dS swampland bounds. But often in these discussions the heat bath dy…
A General Prescription for Semi-Classical Holography
Budhaditya Bhattacharjee, Chethan Krishnan
We present a version of holographic correspondence where bulk solutions with sources localized on the holographic screen are the key objects of interest, and not bulk solutions def…
de Sitter, -Corrections & Duality Invariant Cosmology
Chethan Krishnan
Demanding -duality covariance, Hohm and Zwiebach have written down the action for the most general cosmology involving the metric, -field and dilaton, to all orders in $…
A Hairy Box in Three Dimensions
Chethan Krishnan, Rohit Shekhar, P. N. Bala Subramanian
In this short note, we consider the phases of gravity coupled to a gauge field and charged scalar in 2+1 dimensions without a cosmological constant, but with box boundary co…
Bulk Locality and Asymptotic Causal Diamonds
Chethan Krishnan
In AdS/CFT, the non-uniqueness of the reconstructed bulk from boundary subregions has motivated the notion of code subspaces. We present some closely related structures that arise…
