Extremal Chaos
Sandipan Kundu
In maximally chaotic quantum systems, a class of out-of-time-order correlators (OTOCs) saturate the Maldacena-Shenker-Stanford (MSS) bound on chaos. Recently, it has been shown tha…
Subleading Bounds on Chaos
Sandipan Kundu
Chaos, in quantum systems, can be diagnosed by certain out-of-time-order correlators (OTOCs) that obey the chaos bound of Maldacena, Shenker, and Stanford (MSS). We begin by derivi…
Swampland Conditions for Higher Derivative Couplings from CFT
Sandipan Kundu
There are effective field theories that cannot be embedded in any UV complete theory. We consider scalar effective field theories, with and without dynamical gravity, in -dimens…
EFT of 6D SUSY RG Flows
Jonathan J. Heckman, Sandipan Kundu, Hao Y. Zhang
Motivated by its potential use in constraining the structure of 6D renormalization group flows, we determine the low energy dilaton-axion effective field theory of conformal and gl…
