Symmetry-resolved Entanglement Entropy, Spectra & Boundary Conformal Field Theory
Yuya Kusuki, Sara Murciano, Hirosi Ooguri +1
We perform a comprehensive analysis of the symmetry-resolved (SR) entanglement entropy (EE) for one single interval in the ground state of a D conformal field theory (CFT), th…
Lightcone Modular Bootstrap and Tauberian Theory: A Cardy-like Formula for Near-extremal Black Holes
Sridip Pal, Jiaxin Qiao
We show that for a unitary modular invariant 2D CFT with central charge and having a nonzero twist gap in the spectrum of Virasoro primaries, for sufficiently large spin ,…
Holographic Weyl anomaly in string theory
Lorenz Eberhardt, Sridip Pal
We compute the worldsheet sphere partition function of string theory on global AdS with pure NS-NS flux. Because of an unfixed Möbius symmetry on the worldsheet, there is a can…
Twist accumulation in conformal field theory. A rigorous approach to the lightcone bootstrap
Sridip Pal, Jiaxin Qiao, Slava Rychkov
We prove that in any unitary CFT, a twist gap in the spectrum of operator product expansion (OPE) of identical scalar primary operators (i.e. ) implies the existence of…
(Half) Wormholes under Irrelevant Deformation
Diptarka Das, Sridip Pal, Anurag Sarkar
Recently it has been shown by Almheiri and Lin [1] that the reconstruction of black-hole interior is sensitive to knowing the exact coupling of the boundary theory even if the coup…
Automorphic Spectra and the Conformal Bootstrap
Petr Kravchuk, Dalimil Mazac, Sridip Pal
We describe a new method for constraining Laplacian spectra of hyperbolic surfaces and 2-orbifolds. The main ingredient is consistency of the spectral decomposition of integrals of…
Universal fine grained asymptotics of free and weakly coupled Quantum Field Theory
Weiguang Cao, Tom Melia, Sridip Pal
We give a rigorous proof that in any free quantum field theory with a finite group global symmetry , on a compact spatial manifold, at sufficiently high energy, the den…
The Disk Partition Function in String Theory
Lorenz Eberhardt, Sridip Pal
We investigate the disk partition function for the open string. This is a subtle problem because of the presence of a residual gauge group on the world…
Spontaneously Broken Boosts in CFTs
Zohar Komargodski, Márk Mezei, Sridip Pal +1
Conformal Field Theories (CFTs) have rich dynamics in heavy states. We describe the constraints due to spontaneously broken boost and dilatation symmetries in such states. The spon…
Universality in asymptotic bounds and its saturation in D CFT
Diptarka Das, Yuya Kusuki, Sridip Pal
We study asymptotics of three point coefficients (light-light-heavy) and two point correlators in heavy states in unitary, compact D CFTs. We prove an upper and lower bound on s…
EFT Asymptotics: the Growth of Operator Degeneracy
Tom Melia, Sridip Pal
We establish formulae for the asymptotic growth (with respect to the scaling dimension) of the number of operators in effective field theory, or equivalently the number of -matr…
High Energy Modular Bootstrap, Global Symmetries and Defects
Sridip Pal, Zhengdi Sun
We derive Cardy-like formulas for the growth of operators in different sectors of unitary dimensional CFT in the presence of topological defect lines by putting an upper and lo…
Beurling-Selberg Extremization and Modular Bootstrap at High Energies
Baur Mukhametzhanov, Sridip Pal
We consider previously derived upper and lower bounds on the number of operators in a window of scaling dimensions at asymptotically large in 2d unitary modular i…
Tauberian-Cardy formula with spin
Sridip Pal, Zhengdi Sun
We prove a dimensional Tauberian theorem in context of dimensional conformal field theory. The asymptotic density of states with conformal weight $(h,\bar{h})\to (\infty,\i…

We use methods inspired from complex Tauberian theorems to make progress in understanding the asymptotic behavior of the magnitude of heavy-light-heavy three point coefficients rig…
Bounds on the density of states and the spectral gap in CFT
Shouvik Ganguly, Sridip Pal
We improve the recently discovered upper and lower bounds on the correction to the Cardy formula for the density of states integrated over an energy window (of width ),…
The Spinful Large Charge Sector of Non-Relativistic CFTs: From Phonons to Vortex Crystals
S. M. Kravec, Sridip Pal
We study operators in Schrödinger invariant field theories (non-relativistic conformal field theories or NRCFTs) with large charge (particle number) and spin. Via the state-operato…
Nonrelativistic Conformal Field Theories in the Large Charge Sector
S. M. Kravec, Sridip Pal
We study Schrödinger invariant field theories (nonrelativistic conformal field theories) in the large charge (particle number) sector. We do so by constructing the effective field…
Existence and Construction of Galilean invariant Theories
Benjamin Grinstein, Sridip Pal
We prove a no-go theorem for the construction of a Galilean boost invariant and anisotropic scale invariant field theory with a finite dimensional basis of fields. Two poi…
Unitarity and Universality in non relativistic Conformal Field theory
Sridip Pal
We relate the notion of unitarity of a invariant field theory with that of a Schrodinger field theory using the fact that is a subgroup of Sch…
Modular crossings, OPE coefficients and black holes
Diptarka Das, Shouvik Datta, Sridip Pal
In (1+1)-d CFTs, the 4-point function on the plane can be mapped to the pillow geometry and thereby crossing symmetry gets translated into a modular property. We use these modular…
Monstrous entanglement
Diptarka Das, Shouvik Datta, Sridip Pal
The Monster CFT plays an important role in moonshine and is also conjectured to be the holographic dual to pure gravity in AdS3. We investigate the entanglement and Renyi entropies…
Charged structure constants from modularity
Diptarka Das, Shouvik Datta, Sridip Pal
We derive a universal formula for the average heavy-heavy-light structure constants for 2d CFTs with non-vanishing u(1) charge. The derivation utilizes the modular properties of on…

Pallab Basu, Diptarka Das, Shouvik Datta +1
The Eigenstate Thermalization Hypothesis (ETH) provides a way to understand how an isolated quantum mechanical system can be approximated by a thermal density matrix. We find a cla…
