Abstract：
I will discuss recent developments in the SCOPE (Screened Couplings and Pauli Exclusion) research program, with Luca Visinelli, aimed at exploring experimentally accessible signatures of physics beyond the Standard Model and General Relativity. The first part of the talk will focus on quantum-gravity-induced modifications of particle statistics in noncommutative spacetime and string-inspired quantum field theories, where θ-deformed Poincaré symmetry may lead to tiny violations of the Pauli Exclusion Principle. I will discuss recent progress toward relativistic formulations of these models and possible tests through anomalous atomic transitions in xenon-based detectors such as PandaX. The second part will address screened scalar fields, including chameleons and symmetrons, as candidates for dark energy and modified gravity. I will review recent studies of solar chameleon production and their possible detection in xenon experiments, together with Bayesian analyses of XENONnT data constraining effective scalar couplings and connecting laboratory searches with cosmology.
Biography：
Antonino Marcianò is a tenured Full Professor in the Department of Physics at Fudan University and a member of the Italian National Institute for Nuclear Physics (INFN). He joined the Fudan faculty in 2014, where his research has focused on gravitational-wave probes of the dark universe. Previously, he held postdoctoral positions in the United States at Princeton University and Dartmouth College, working on models of cosmological inflation and the physics of the cosmic microwave background, as well as at Aix-Marseille University, where he contributed to the Wilson-loop approach to quantum gravity. His interest in quantum gravity — particularly in noncommutative geometry and quantum-group deformations of spacetime symmetries — originated during his Ph.D. studies at Sapienza University of Rome.
