On-Shell Action for Type IIB Supergravity and Superstrings on
Subhroneel Chakrabarti, Divyanshu Gupta, Arkajyoti Manna
AdS/CFT predicts that the value of the on-shell action for type IIB Supergravity (SUGRA) on background must be a non-zero number completely determined from the b…
Renormalisation in -Deformed (Non-)Integrable Theories
Subhroneel Chakrabarti, Arkajyoti Manna, Madhusudhan Raman
That the exact quantum S-matrix of -deformed field theories is known has interesting consequences for their perturbative renormalisation. Recent investigati…
Irrelevant Deformations of Chiral Bosons
Subhroneel Chakrabarti, Divyanshu Gupta, Arkajyoti Manna +1
We study deformations of chiral bosons using the formalism due to Sen. For arbitrary numbers of left- and right-chiral bosons, we find that the $ \t…
Black Hole Hair Removal For N=4 CHL Models
Subhroneel Chakrabarti, Suresh Govindarajan, P Shanmugapriya +2
Although BMPV black holes in flat space and in Taub-NUT space have identical near-horizon geometries, they have different indices from the microscopic analysis. For K3 compactifica…
Chiral Decoupling from Irrelevant Deformations
Subhroneel Chakrabarti, Madhusudhan Raman
We show that at the level of the equations of motion (i.e. classically), in the limit in which the deformation parameter is sent to infinity, the le…
Generalised Garfinkle-Vachaspati Transform With Dilaton
Subhroneel Chakrabarti, Deepali Mishra, Yogesh K. Srivastava +1
The generalised Garfinkle-Vachaspati transform (GGV) introduced in our previous work (arXiv:1808.04981) is a powerful technique to add hair modes to a class of known D1-D5 solution…
Amplitudes Involving Massive States Using Pure Spinor Formalism
Subhroneel Chakrabarti, Sitender Pratap Kashyap, Mritunjay Verma
Same amplitudes evaluated independently using RNS and pure spinor formalism are expected to agree. While for massless states, this fact has been firmly established, for massive sta…
Integrated Massive Vertex Operator in Pure Spinor Formalism
Subhroneel Chakrabarti, Sitender Pratap Kashyap, Mritunjay Verma
We construct the integrated vertex operator for the first massive states of open superstrings with in the pure spinor formalism of the superstring theory. This vert…
Testing Subleading Multiple Soft Graviton Theorem for CHY Prescription
Subhroneel Chakrabarti, Sitender Pratap Kashyap, Biswajit Sahoo +2
In arXiv:1707.06803 we derived the subleading multiple soft graviton theorem in a generic quantum theory of gravity for arbitrary number of soft external gravitons and arbitrary nu…
SYK Model, Chaos and Conserved Charge
Ritabrata Bhattacharya, Subhroneel Chakrabarti, Dileep P. Jatkar +1
We study the SYK model with complex fermions, in the presence of an all-to-all -body interaction, with a non-vanishing chemical potential. We find that, in the large limit,…
Subleading Soft Theorem for Multiple Soft Gravitons
Subhroneel Chakrabarti, Sitender Pratap Kashyap, Biswajit Sahoo +2
We derive the subleading soft graviton theorem in a generic quantum theory of gravity for arbitrary number of soft external gravitons and arbitrary number of finite energy external…
Theta Expansion of First Massive Vertex Operator in Pure Spinor
Subhroneel Chakrabarti, Sitender Pratap Kashyap, Mritunjay Verma
We provide the covariant superspace equations that are sufficient to determine the complete expansion of the vertex operator of the open string massive states with $(mass)^2=1/…
