Action-angle variables and phase space formulation of Hermitian matrix models
Arghya Chattopadhyay
We develop a phase space description of large Hermitian one matrix models directly from the recursions satisfied by the orthogonal polynomials. In the one-cut phase, the recurs…
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,…
Weyl formula and thermodynamics of geometric flow
Parikshit Dutta, Arghya Chattopadhyay
We study the Weyl formula for the asymptotic number of eigenvalues of the Laplace-Beltrami operator with Dirichlet boundary condition on a Riemannian manifold in the context of geo…
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…
Spread complexity as classical dilaton solutions
Arghya Chattopadhyay, Arpita Mitra, Hendrik J. R. van Zyl
We demonstrate a relation between Nielsen's approach towards circuit complexity and Krylov complexity through a particular construction of quantum state space geometry. We start by…
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…
Flow of shear response functions in hyperscaling violating Lifshitz theories
Arghya Chattopadhyay, Nihal M, Debangshu Mukherjee
We study the flow equations of the shear response functions for hyperscaling violating Lifshitz (hvLif) theories, with Lifshitz and hyperscaling violating exponents and . Ad…
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…
From 2d Droplets to 2d Yang-Mills
Arghya Chattopadhyay, Suvankar Dutta, Debangshu Mukherjee +1
We establish a connection between time evolution of free Fermi droplets and partition function of \emph{generalised} \emph{q}-deformed Yang-Mills theories on Riemann surfaces. Clas…
Quantum Mechanics of Plancherel Growth
Arghya Chattopadhyay, Suvankar Dutta, Debangshu Mukherjee +1
Growth of Young diagrams, equipped with Plancherel measure, follows the automodel equation of Kerov. Using the technology of unitary matrix model we show that such growth process i…
Chern-Simons Theory on Seifert Manifold and Matrix Model
Arghya Chattopadhyay, Suvankar Dutta, Neetu
Chern-Simons (CS) theories with rank and level on Seifert manifold are discussed. The partition functions of such theories can be written as a function of modular transform…
Matrix Model for Riemann Zeta via its Local Factors
Arghya Chattopadhyay, Parikshit Dutta, Suvankar Dutta +1
We propose the construction of an ensemble of unitary random matrices (UMM) for the Riemann zeta function. Our approach to this problem is `-iecemeal', in the sense that we cons…
Emergent Phase Space Description of Unitary Matrix Model
Arghya Chattopadhyay, Parikshit Dutta, Suvankar Dutta
We show that large phases of a dimensional generic unitary matrix model (UMM) can be described in terms of topologies of two dimensional droplets on a plane spanned by eige…
