Are there Einsteinian gravities involving covariant derivatives of the Riemann tensor?
Journal of High Energy Physics, 2022 We study the particle content of higher derivative theories of gravity built with contractions of the Riemann tensor and its covariant derivatives. In the absence of the latter, there is a family of theories exhibiting an Einsteinian spectrum known as ...

Advanced Science, EarlyView.This study presents a hybrid quantum‐classical framework for accurate prediction of protein structures on utility‐level quantum processors. We evaluate the practical application of the Variational Quantum Eigen‐solver (VQE) in protein structure prediction and demonstrate its superiority over state‐of‐the‐art deep learning methods in molecular docking ...

Self-dual pp-wave solutions in chiral higher-spin gravity
Journal of High Energy PhysicsWe show that chiral higher-spin gravity with a vanishing cosmological constant admits a class of exact self-dual pp-wave solutions derived from harmonic scalar functions and two principal spinors.

A pilot study on canonical gravity with mass dimension one fermions
Journal of High Energy Physics, 2022 The mass dimension one (MDO) fermionic field is built on a complete set of dual-helicity eigenspinors of the charge conjugation operator, which obeys the statistic of Fermi-Dirac.

SUPSERSEDED VERSION – Historical Draft OnlyREADERS:This document represents an early-stage draft developed during the initial conceptual exploration of the Gravity of Probability (GoP) framework. The ideas here served as stepping stones toward the fully unified, mathematically consistent formulation that now incorporates probabilistic curvature, the ...

Integrable deformations of the AdS5×S5 superstring and the classical Yang-Baxter equation - Towards the gravity/CYBE correspondence - [PDF]
, 2014 Based on the formulation of Yang-Baxter sigma models developed by Klimcik and Delduc-Magro-Vicedo, we explain that various deformations of type IIB superstring on AdS5 × S5 can be charactered by classical r-matrices satisfying the classical Yang-Baxter ...

Effective Theories of Classical Gravity
, 2012 AbstractIf the concepts underlying Effective Theory were appreciated from the earliest days of Newtonian gravity, Le Verrier’s announcement in 1845 of the anomalous perihelion precession of Mercury would have been no surprise. Furthermore, the size of the effect could have been anticipated through “naturalness” arguments well before the definitive ...

Advanced Science, EarlyView.An evolutionary molecular dynamics platform is used to design P1.6, a membrane‐active peptide that senses lipid packing defects in viral envelopes. P1.6 adopts a stabilized α‐helical structure upon membrane contact, disrupts virus‐like liposomes, and damages HIV‐1 particles.

Higher order gravities and the Strong Equivalence Principle
Journal of High Energy Physics, 2017 We show that, in all metric theories of gravity with a general covariant action, gravity couples to the gravitational energy-momentum tensor in the same way it couples to the matter energy-momentum tensor order by order in the weak field approximation ...

Bounce Loop Quantum Cosmology Corrected Gauss-Bonnet Gravity
, 2015 We develop a Gauss-Bonnet extension of Loop Quantum Cosmology, by introducing holonomy corrections in modified $F(\mathcal{G})$ theories of gravity.
