-Expansions Near Three Dimensions from Conformal Field Theory
Pallab Basu, Chethan Krishnan
We formally extend the CFT techniques introduced in arXiv:1505.00963, to theory in dimensions and use it to compute anomalous dimensions near $d_…
Gauging Away a Big Bang
Chethan Krishnan, Avinash Raju
We argue that in the tensionless phase of string theory where the stringy gauge symmetries are unbroken, (at least some) cosmological singularities can be understood as gauge artef…
A Note on D1-D5 Entropy and Geometric Quantization
Chethan Krishnan, Avinash Raju
We quantize the space of 2-charge fuzzballs in IIB supergravity on . The resulting entropy precisely matches the D1-D5 black hole entropy, including a specific numerical coeffi…
A Hidden Symmetry of AdS Resonances
Oleg Evnin, Chethan Krishnan
Recent investigations have revealed powerful selection rules for resonant energy transfer between modes of non-linear perturbations in global anti-de Sitter (AdS) space-time. It is…
AdS (In)stability: Lessons From The Scalar Field
Pallab Basu, Chethan Krishnan, P. N. Bala Subramanian
We argued in arXiv:1408.0624 that the quartic scalar field in AdS has features that could be instructive for answering the gravitational stability question of AdS. Indeed, the cons…
