New Frontiers of Quantum Field and Gravity

5 Jan 2026, 08:00 → 16 Jan 2026, 18:00 Asia/Shanghai

Peking University

 

In recent years, an emerging common theme in quantum field theories and gravity is the exploration of Lorentzian methods and scattering data at asymptotic infinity to uncover fundamental properties of underlying theories. This approach manifests in diverse areas, including the study of scattering amplitudes and the S-matrix in gauge and gravity theories, the exploration of Lorentzian methods in conformal field theories, the use of asymptotic data for integrable systems, the analysis of gravitational waves from black hole mergers and energy flow from particle collisions. This program will bring together leading experts to discuss current progress and outstanding challenges in amplitudes, conformal bootstrap, energy correlators, gravitational waves, integrability, and S-matrix bootstrap. The goal is to foster discussion and catalyze new collaborations between these subfields, as well as to strengthen the dialogue between theory and experiment, paving the way for new developments.

 

The structure of the program is as follows:

Week 1 (Jan 5, 2026 -- Jan 9, 2026) : Dedicated lecture sessions on the aforementioned topics.

Week 2 (Jan 12, 2026 -- Jan 16, 2026): Research talks highlighting the latest advancements in these areas.

11 Fourier Integrals for Gravitational Radiation

Gravitational radiation from the scattering of two compact objects can be computed directly from scattering amplitudes within the observable-based (KMOC) formalism. In this approach, the waveform in frequency space is obtained from Fourier integrals of radiative 2→3 scattering amplitudes. In this talk, I focus on the analytic and algebraic structure of these Fourier integrals and show how they belong to the mathematical class of twisted period integrals. I explain how they exhibit a finite-dimensional vector-space structure and satisfy linear and quadratic relations, as well as systems of differential equations in the kinematic invariants. Using these techniques, we compute for the first time the fully analytic next-to-leading order (NLO) gravitational radiation at all orders in velocity. This framework provides a systematic and extensible pathway towards higher-precision gravitational-wave predictions, including higher perturbative orders and the inclusion of spin effects.
