The Routh of the Attractor Mechanism
Arghya Chattopadhyay, Alessio Marrani, Sourav Roychowdhury
We investigate and clarify various aspects of the effective dynamics of Maxwell-Einstein-scalar theories in the background of static, spherically symmetric and asymptotically flat…

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…

Krylov complexity of deformed conformal field theories
Arghya Chattopadhyay, Vinay Malvimat, Arpita Mitra
We consider a perturbative expansion of the Lanczos coefficients and the Krylov complexity for two-dimensional conformal field theories under integrable deformations. Specifically,…
