Physical Effects of the Gravitational -Parameter
Willy Fischler, Sandipan Kundu
We describe the effect of the gravitational -parameter on the behavior of the stretched horizon of a black hole in -dimensions. The gravitational -term is a total deri…
Averaged Null Energy Condition from Causality
Thomas Hartman, Sandipan Kundu, Amirhossein Tajdini
Unitary, Lorentz-invariant quantum field theories in flat spacetime obey microcausality: commutators vanish at spacelike separation. For interacting theories in more than two dimen…
Efficient L1-Norm Principal-Component Analysis via Bit Flipping
Panos P. Markopoulos, Sandipan Kundu, Shubham Chamadia +1
It was shown recently that the L1-norm principal components (L1-PCs) of a real-valued data matrix ( data samples of dimensions) ca…
Einstein gravity 3-point functions from conformal field theory
Nima Afkhami-Jeddi, Thomas Hartman, Sandipan Kundu +1
We study stress tensor correlation functions in four-dimensional conformal field theories with large and a sparse spectrum. Theories in this class are expected to have local ho…
Emergent Horizons and Causal Structures in Holography
Avik Banerjee, Arnab Kundu, Sandipan Kundu
The open string metric arises kinematically in studying fluctuations of open string degrees of freedom on a D-brane. An observer, living on a probe D-brane, can send signals throug…
Aspects of Holographic Entanglement at Finite Temperature and Chemical Potential
Sandipan Kundu, Juan F. Pedraza
We investigate the behavior of entanglement entropy at finite temperature and chemical potential for strongly coupled large-N gauge theories in -dimensions () that are d…
Spread of entanglement for small subsystems in holographic CFTs
Sandipan Kundu, Juan F. Pedraza
We develop an analytic perturbative expansion to study the propagation of entanglement entropy for small subsystems after a global quench, in the context of the AdS/CFT corresponde…
A New Spin on Causality Constraints
Thomas Hartman, Sachin Jain, Sandipan Kundu
Causality in a shockwave state is related to the analytic properties of a four-point correlation function. Extending recent results for scalar probes, we show that this constrains…
