All-order celestial OPE from on-shell recursion
Journal of High Energy Physics, 2023 We determine tree level, all-order celestial operator product expansions (OPEs) of gluons and gravitons in the maximally helicity violating (MHV) sector.

A Bioinspired Sensory‐CAPode With Dual Functionality: Logic Gate and Real‐Time Biosensing
Advanced Functional Materials, EarlyView.An electrochemical capacitor diode (CAPode) redefines the frontier of iontronics by seamlessly unifying logic computing and biosensing within a single biocompatible platform. Inspired by nature's own ion‐channel circuitry, this elegant ionic system transforms complex chemical signals into precise electrical responses, paving the way for next‐generation

Black holes in the gravity/gauge theory correspondence [PDF]
, 2002 The AdS/CFT correspondence provides a microscopic description of black hole thermodynamics. In this thesis, I study the relation between the classical physics of black holes and this microscopic description.

Advanced Functional Materials, EarlyView.Gate bias is used to cancel Duffing nonlinearity in atomically thin MoS2 drumhead resonators, switching their response from hardening to softening and creating a nearly linear operating point. This electrical control suppresses hysteresis, enables stronger linear drive, and improves signal‐to‐noise ratio, offering a practical route to stable 2D NEMS ...

A Holographic Description of Black Hole Microstates [PDF]
, 2022 We review the basic features of black holes in General Relativity, their thermodynamic behaviour and the paradoxes that emerge when one take this behaviour seriously. We introduce string theory and supergravity and black hole physics within string theory.

Advanced Functional Materials, EarlyView.A tree‐inspired hydrogel interfacial reactor couples solar evaporation with photocatalysis for simultaneous desalination and waste water treatment. The bilayer design achieves 2.14 kg·m−2·h−1 evaporation rate with 79% dye degradation under one sun, demonstrating that photothermal heating and evaporation induced pollutant enrichment create a self ...

Giant Electrostriction in Halide Perovskites Revisited With Double‐Modulation Interferometry
Advanced Functional Materials, EarlyView.A giant electrostrictive effect in lead halide perovskites had been reported previously. This work uses sensitive interferometry to measure the electromechanical response of various halide perovskite samples. The results reveal no intrinsic electrostrictive compression. Instead, the materials expand primarily under an applied electric field as a result

On black holes in string theory [PDF]
, 2011 PhDThis thesis investigates black holes in string theory through string amplitudes and through gauge-gravity duality. The research presented in this thesis supports the claim that string theory is capable of a consistent quantum-mechanical description

Neutrino quasinormal modes of a Kerr-Newman-de Sitter black hole [PDF]
, 2005 Using the Poshl-Teller approximation, we evaluate the neutrino quasinormal modes (QNMs) of a Kerr-Newman-de Sitter black hole. The result shows that for a Kerr-Newman-de Sitter black hole, massless neutrino perturbation of large A, positive m and small ...
