Resummation of Universal Tails in Gravitational Waveforms
Mikhail M. Ivanov, Yue-Zhou Li, Julio Parra-Martinez +1
We present a formula for the universal anomalous scaling of the multipole moments of a generic gravitating source in classical general relativity. We derive this formula in two ind…
Gravitational Raman Scattering: a Systematic Toolkit for Tidal Effects in General Relativity
Mikhail M. Ivanov, Yue-Zhou Li, Julio Parra-Martinez +1
We present a framework for systematic computations of scattering amplitudes for gravitational Raman scattering, -- the inelastic scattering of massless fields off compact relativis…
Stochastic inflation as an open quantum system
Yue-Zhou Li
We reinterpret Starobinsky's stochastic inflation as an open quantum system, where short-wavelength modes act as the environment for long-wavelength modes. Using the Schwinger-Keld…
Regge trajectories, detectors, and distributions in the critical model
Yue-Zhou Li, David Simmons-Duffin
We explore light-ray operators in the critical O model in the large- limit, focusing on leading-twist and leading ``horizontal" trajectories. We distinguish between light-r…
Gravitational Raman Scattering in Effective Field Theory: a Scalar Tidal Matching at
Mikhail M. Ivanov, Yue-Zhou Li, Julio Parra-Martinez +1
We present a framework to compute amplitudes for the gravitational analog of the Raman process, a quasi-elastic scattering of waves off compact objects, in worldline effective fiel…
The no boundary density matrix
Victor Ivo, Yue-Zhou Li, Juan Maldacena
We discuss a no-boundary proposal for a subregion of the universe. In the classical approximation, this density matrix involves finding a specific classical solution of the equatio…
