  1. 97. Modeling of a seismic attenuation system for gravitational wave detectors
    Alessandro Kotchian (INFN Perugia, Univ. Perugia)
    16/05/2026, 09:00
    Oral presentation

    In this project will be presented the implementation of deep reinforcement learning for seismic noise attenuation in gravitational-wave detectors.
    From the creation of the envirorment to the training of agents for the stabilization of mirror.

  2. 96. Numerical modeling of quantum noise in gravitational wave detectors
    Greta Tosti
    16/05/2026, 09:20
    Oral presentation

    This project simulates the quantum noise of gravitational wave interferometric detectors in different configurations: no squeezing injection, frequency independent squeezing and frequency dependent squeezing (with filter cavity). Key features: implementation of substrate losses, intra-cavity arm losses and EPR squeezing injection.

  3. 100. Differentiable programming for experiment design optimization in precision physics experiments
    Mateusz Bawaj (University of Perugia)
    16/05/2026, 09:40
    Oral presentation

    Quantum noise reduction techniques are key to improving gravitational-wave detector sensitivity, yet their design involves tightly coupled parameters typically tuned via skilled human designer.

    We propose an end-to-end differentiable programming framework in which the quantum noise reduction chain is modelled as a parametrized simulator, enabling direct computation of gradients of...
