SUMMARY:Williams Dhelonga (UNamur)
DESCRIPTION:Title : Exploring Weak measurements within the Einstein-Dirac Cosmological framework. \nAbstract : Our study applies the Two-State Formalism alongside weak measurements within a spatially homogeneous and isotropic cosmological framework\, wherein Dirac spinors are intricately coupled to classical gravity. To elucidate this\, we provide detailed formulations for computing the weak values of the energy-momentum tensors\, the Z component of spin\, and the characterization of pure states. Weak measurements appear to be a generalization and extension of the computation already made by Finster an Hainzl\, in A spatially homogeneous and isotropic Einstein-Dirac cosmology. Our analysis reveals that the acceleration of the Universe expansion can be understood as an outcome of postselection\, underscoring the effectiveness of weak measurement as a discerning approach for gauging cosmic acceleration. https://arxiv.org/abs/2405.02108 \n\nThe seminar will take place in Room S08 at the Faculty of Sciences.
