An effective matrix model for dynamical end of the world branes in Jackiw-Teitelboim gravity
Journal of High Energy Physics, 2022 We study Jackiw-Teitelboim gravity with dynamical end of the world branes in asymptotically nearly AdS2 spacetimes. We quantize this theory in Lorentz signature, and compute the Euclidean path integral summing over topologies including dynamical branes ...

Gravitational memory in higher dimensions
Journal of High Energy Physics, 2018 It is shown that there is a universal gravitational memory effect measurable by inertial detectors in even spacetime dimensions d ≥ 4. The effect falls off at large radius r as r 3−d .

Celestial amplitudes from UV to IR
Journal of High Energy Physics, 2021 Celestial amplitudes represent 4D scattering of particles in boost, rather than the usual energy-momentum, eigenstates and hence are sensitive to both UV and IR physics.

The rule of law and the law of nature
Filosofický časopis, 2021 Traditionally, the understanding of the Greek notion of νόμος, especially concerning the notion as it was conceived in Athens, has been hindered by a tendency to project modern interpretations of the law onto the ancient mentality and praxis. The first confusion comes from the exclusive identification of νόμος with the modern concept of law, which ...

Aspects of AdS2 quantum gravity and the Karch-Randall braneworld
Journal of High Energy Physics, 2022 In this paper, we use the Karch-Randall braneworld to study theories of quantum gravity in two dimensional (nearly) anti-de Sitter space (AdS2). We focus on effective gravitational theories in the setup with two Karch-Randall branes embedded in an ...

A d-dimensional stress tensor for Minkd+2 gravity
Journal of High Energy Physics, 2018 We consider the tree-level scattering of massless particles in (d+2)-dimensional asymptotically flat spacetimes. The S $$ \mathcal{S} $$-matrix elements are recast as correlation functions of local operators living on a space-like cut ℳ d of the null ...

Asymptotic symmetries and celestial CFT
Journal of High Energy Physics, 2020 We provide a unified treatment of conformally soft Goldstone modes which arise when spin-one or spin-two conformal primary wavefunctions become pure gauge for certain integer values of the conformal dimension ∆.

Concepts of law of nature [PDF]
, 2011 Over the past 50 years, there has been a great deal of philosophical interest in laws of nature, perhaps because of the essential role that laws play in the formulation of, and proposed solutions to, a number of perennial philosophical problems.

How Was Nature Able to Discover Its Own Laws—Twice?
, 2021 The central thesis of the modern scientific revolution is that nature is objective. Yet, somehow, out of that objective reality, projective systems emerged—cognitive and purposeful.

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This
