Complementarity and the unitarity of the black hole S-matrix [PDF]
Journal of High Energy Physics, 2022 Recently, Akers et al. proposed a non-isometric holographic map from the interior of a black hole to its exterior. Within this model, we study properties of the black hole S -matrix, which are in principle accessible to observers who stay outside the ...

Rigorous Bounds on the Analytic S Matrix. [PDF]
Physical Review Letters, 2021 We consider a dual S-matrix bootstrap approach in d≥3 space-time dimensions which relies solely on the rigorously proven analyticity, crossing, and unitarity properties of the scattering amplitudes.

S-matrix bootstrap for effective field theories: massless pions [PDF]
Journal of High Energy Physics, 2020 We use the numerical S-matrix bootstrap method to obtain bounds on the two leading Wilson coefficients (or low energy constants) of the chiral lagrangian controlling the low-energy dynamics of massless pions.

Carving out the space of open-string S-matrix [PDF]
Journal of High Energy Physics, 2020 In this paper, we explore the open string amplitude’s dual role as a space-time S-matrix and a 2D holomorphic CFT correlation function. We pursue this correspondence in two directions.

The soft S $$ \mathcal{S} $$ -matrix in gravity
Journal of High Energy Physics, 2020 The gravitational S $$ \mathcal{S} $$ -matrix defined with an infrared (IR) cutoff factorizes into hard and soft factors. The soft factor is universal and contains all the IR and collinear divergences.

S-Matrix and Anomaly of de Sitter [PDF]
Symmetry, 2020 S-matrix formulation of gravity excludes de Sitter vacua. In particular, this is organic to string theory. The S-matrix constraint is enforced by an anomalous quantum break-time proportional to the inverse values of gravitational and/or string couplings.

Contour integrals and the modular S $$ \mathcal{S} $$ -matrix
Journal of High Energy Physics, 2020 We investigate a conjecture to describe the characters of large families of RCFT’s in terms of contour integrals of Feigin-Fuchs type. We provide a simple algorithm to determine the modular S $$ \mathcal{S} $$ -matrix for arbitrary numbers of characters ...

Nanoscale precipitations in deformed dilute alloying Mg-Zn-Gd alloy
Materials & Design, 2020 Nanoscale precipitations in deformed dilute alloying Mg-Zn-RE alloys usually play critical positive roles in mechanical properties, while characterizing them still poses a significant challenge due to their small size and low volume fraction.

Celestial insights into the S-matrix bootstrap
Journal of High Energy Physics, 2022 We consider 2-2 scattering in four spacetime dimensions in Celestial variables. Using the crossing symmetric dispersion relation (CSDR), we recast the Celestial amplitudes in terms of crossing symmetric partial waves.
