    QFT-GW Group Meetings

    → Asia/Shanghai
    1502 (Shing-Tung Yau Center)

    1502

    Shing-Tung Yau Center

    Yifu Arch Building, Sipailou, Southeast University
    Description

    The QFT-GW Group Meetings are weekly meetings of our research group working on topics at the interface of Quantum Field Theory (QFT) and Gravitational Waves (GW). They provide a regular forum for sharing research progress, discussing ongoing projects, exploring the literature, and fostering interaction and collaboration among group members.

    Each weekly meeting consists of two parts:

    Part I — Weekly Research Updates

    Each group member briefly summarizes their research activities and progress over the past week. These updates are intended to keep everyone informed about ongoing work and to identify topics that may benefit from further discussion or collaboration. Updates should be kept to no more than 10 minutes per person; detailed technical discussions can be arranged separately.

    Part II — Project Presentation or Journal Club

    The second part of the meeting alternates between:

    • Project presentations / internal seminars: With several research projects running in parallel within the group, these presentations provide an opportunity to introduce ongoing projects to the entire group. Talks should give a comprehensive and accessible overview of the background, motivation, scientific questions, goals, methodology, current progress, and open problems. They should be designed to be understandable to group members who are not directly involved in the project.

    • Journal club: Sessions devoted to reading and discussing interesting papers, including both recent developments and classic works relevant to the group's research interests.

        Project presentation: Conservative dynamics beyond Einstein 1h

        This talk will provide an overview of the worldline effective field theory (EFT) approach to relativistic binary systems. I will first introduce several key ingredients of the EFT framework, including the construction of integrands for physical observables, integration-by-parts (IBP) reduction of Feynman integrals, and the method of differential equations for evaluating master integrals analytically.

        I will then discuss our previous work on the conservative dynamics of binary systems in Einstein-scalar-Gauss-Bonnet (ESGB) gravity, focusing on our calculation of the impulse and scattering angle through third post-Minkowskian (3PM) order.
