Freudenthal Duality in Conformal Field Theory
Arghya Chattopadhyay, Taniya Mandal, Alessio Marrani
Rotational Freudenthal duality (RFD) relates two extremal Kerr-Newman (KN) black holes (BHs) with different angular momenta and electric-magnetic charges, but with the same Bekenst…
Generalized Freudenthal duality for rotating extremal black holes
Arghya Chattopadhyay, Taniya Mandal, Alessio Marrani
Freudenthal duality (FD) is a non-linear symmetry of the Bekenstein-Hawking entropy of extremal dyonic black holes (BHs) in Maxwell-Einstein-scalar theories in four space-time dime…
Holographic Thermal Correlators for Hyperbolic s
Atanu Bhatta, Shankhadeep Chakrabortty, Taniya Mandal +1
We use holography to compute the exact form of retarded Green's functions for a scalar operator with conformal dimension in a thermal CFT and in its related counterpart with ch…
Black holes and the loss landscape in machine learning
Pranav Kumar, Taniya Mandal, Swapnamay Mondal
Understanding the loss landscape is an important problem in machine learning. One key feature of the loss function, common to many neural network architectures, is the presence of…
Near-Extremal Freudenthal Duality
Arghya Chattopadhyay, Taniya Mandal, Alessio Marrani
Freudenthal duality is, as of now, the unique non-linear map on electric-magnetic (e.m.) charges which is a symmetry of the Bekenstein-Hawking entropy of extremal black holes in Ma…
TsT vs. LCR and Gravity Dual of Non-relativistic Fluid
Suvankar Dutta, Taniya Mandal, Sanhita Parihar
We discuss two different approaches to synthesise holographic non-relativistic fluid from its relativistic counterpart. In the first approach we obtain the non-relativistic fluid b…
Exact thermal correlators of holographic s
Atanu Bhatta, Taniya Mandal
We compute the exact retarded Green's functions in thermal s with chemical potential and angular momenta using holography respectively. We consider the field equations satisfi…
Action complexity of charged black holes with higher derivative interactions
Taniya Mandal, Arpita Mitra, Gurmeet Singh Punia
Quantum complexity of CFT states can be computed holographically from the dual gravitational solutions. In this paper, we have studied the late time growth of holographic complexit…
Equivalence of JT Gravity and Near-extremal Black Hole Dynamics in Higher Derivative Theory
Nabamita Banerjee, Taniya Mandal, Arnab Rudra +1
Two derivative Jackiw Teitelboim gravity theory captures the near horizon dynamics of higher dimensional near extremal black holes, which is governed by a Schwarzian action at the…
Freudenthal duality of near-extremal black holes and Jackiw-Teitelboim gravity
Arghya Chattopadhyay, Taniya Mandal
Freudenthal duality (F-duality), an anti-involution of charge vectors keep the entropy and attractor solutions invariant for an extremal supersymmetric black hole. In this paper, w…
Large Black Holes in an environment
Taniya Mandal, Arunabha Saha
We construct dynamical black hole solutions to Einstein Equations in presence of matter in the large limit. The matter stress tensors that we consider are weak in the sense tha…
Holographic Constraints on Generalised Rivlin-Ericksen Fluid
Suvankar Dutta, Taniya Mandal, Sanhita Parihar
The Rivlin-Ericksen model is one of the oldest models in fluid dynamics to describe non-Newtonian properties. The model comes with two independent transports at second order. In th…

Aditya Kar, Taniya Mandal, Arunabha Saha
We find the membrane equations which describe the leading order in dynamics of black holes in the limit for the most general four-derivative theory of gr…
