Searching for Dark Matter with the Nuclear Lineshape from Laser Spectroscopy Open
The recent laser excitation of the low-lying Th229 isomer transition has started a revolution in ultralight dark matter searches. The enhanced sensitivity of this transition to the large class of dark matter models dominantly coupling to q…

Gravitational waves from first-order phase transitions in LISA: reconstruction pipeline and physics interpretation Open
We develop a tool for the analysis of stochastic gravitational wave backgrounds from cosmological first-order phase transitions with LISA: we initiate a template databank for these signals, prototype their searches, and forecast their reco…

Primordial gravitational waves in the nano-Hertz regime and PTA data — towards solving the GW inverse problem Open
A bstract In recent years, several pulsar timing array collaborations have reported first hints for a stochastic gravitational wave background at nano-Hertz frequencies. Here we elaborate on the possibility that this signal comes from new …

Probing new physics through entanglement in diboson production Open
Pair production of heavy vector bosons is a key process at colliders: it allows to test our understanding of the Standard Model and to explore the existence of new physics through precision measurements of production rates and differential…

Quantum SMEFT tomography: Top quark pair production at the LHC Open
Quantum information observables, such as entanglement measures, provide a powerful way to characterize the properties of quantum states. We propose to use them to probe the structure of fundamental interactions and to search for new physic…

Audible axions with a booster: Stochastic gravitational waves from rotating ALPs Open
Gravitational waves provide a novel way to probe axions or axion-like particles coupled to a dark photon field, even in the absence of couplings to Standard Model particles. In the conventional misalignment mechanism, the generation of an …

Cosmology with the Laser Interferometer Space Antenna Open
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early un…

Gravitational wave echo of relaxion trapping Open
To solve the hierarchy problem, the relaxion must remain trapped in the correct minimum, even if the electroweak symmetry is restored after reheating. In this scenario, the relaxion starts rolling again until the backreaction potential, wi…
