  1. 5. From Strings to Stars: Unlocking the Universe's Acceleration
    Ivonne Zavala (University of Swansea)
    12/02/2025, 13:00

    Recent cosmological observations suggest that dark energy, the driver of the universe's accelerated expansion, may be evolving over time. This challenges the conventional idea of a static cosmological constant within the standard model of cosmology. In this talk, I will explore recent theoretical developments in understanding the nature of dark energy from the perspective of string theory....

  2. 8. An Open Effective Field Theory for light in a medium
    Thomas Colas (University of Cambridge)
    12/02/2025, 13:45

    Open effective field theories seek to incorporate dissipation and noise into our theoretical toolbox. These effects arise from the incomplete modelling of unknown components, which can significantly alter the dynamics of observable degrees of freedom. In this talk, I will introduce open electromagnetism, a sandbox for exploring gauge symmetries in open systems, which describes light in...
