In this talk, I will present our study of the scalar singlet model. In particular, I will discuss the potential probes for electroweak baryogenesis in this model via collider searches, gravitational wave and direct dark matter detection signals. I will show that a large portion of the model parameter space exists where the observation of gravitational waves would allow detection while the indirect collider searches would not. This will motivate my ongoing study of the extended scalar singlet model with a fermionic dark matter candidate.

Weakly interacting massive particles (WIMPs), which are among the best motivated dark matter (DM) candidates, could make up all or only a fraction of the total DM budget. We consider a scenario in which WIMPs are a subdominant DM component; such a scenario would affect both current direct and indirect bounds on the WIMP-nucleon scattering cross section. In this paper we focus on indirect searches for the neutrino flux produced by annihilation of subdominant WIMPs captured by the Sun or the Earth via either spin-dependent or spin-independent scattering. We derive the annihilation rate and the expected neutrino flux at neutrino observatories. In our computation, we include an updated chemical composition of the Earth with respect to the previous literature, leading to an increase of the Earth’s capture rate for spin-dependent scattering by a factor of 3. Results are compared with current bounds from Super-Kamiokande and IceCube. We discuss the scaling of bounds from both direct and indirect detection methods with the WIMP abundance.

I will give an introduction to GAMBIT, the Global and Modular Beyond-the-Standard Inference Tool, focussing on the Beyond-the-Standard-Model science programme currently being pursued with it.  This includes indirect searches for dark matter with gamma-rays and neutrinos, direct searches with a range of underground experiments, cosmological constraints, associated searches for new particles at the LHC and in flavour experiments, and precision tests of the Standard Model.  I will present the latest combined constraints on singlet Higgs-portal dark matter, and on GUT-scale and weak-scale parameterisations of supersymmetry.  I will also briefly discuss GAMBIT extensions on the near horizon.

Anisotropies in the extragalactic electromagnetic emission originated from dark matter represent an emerging tool in the quest for a particle dark matter signal. These anisotropies are due to the cumulative emission from unresolved dark matter structures, which are present at any scale: galaxy clusters, individual galaxies, subhalos inside galaxies. The same structures can be probed by gravitational tracers of the dark matter distribution in the Universe: this is obtained by large-scale-structure surveys, but in the future a good wealth of additional and complementary information will be available from weak lensing surveys. The study of gamma-rays anisotropies and the cross-correlation between the dark matter signal and gravitational tracers offer a novel and powerful opportunity to probe the particle physics nature of dark matter. The talk will introduce details and features of gamma-rays anisotropies and give perspectives of the cross-correlation approach.

I will discuss ongoing work on cavity optomechanical systems, where electromagnetic radiation in a cavity interacts with the motion of nano- or microscale objects via radiation pressure. Such interactions have been exploited in order to bring mechanical systems into the quantum regime, but also in order to manipulate light or microwave radiation. Due to a small coupling constant, this has so far involved driving the cavity with a large number of photons. In this talk, I will discuss how single photons can be controlled or detected using optomechanical interactions. In particular, I will explore whether this is possible even if the system is not in the so-called strong coupling regime.
