Pat Scott, Imperial College London

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.

Chris Kouvaris, CP3-origins Odense

Asymmetric dark matter with sufficiently strong self-interactions might potentially lead to the formation of dark matter compact objects. I will entertain this possibility providing possible ways of distinguishing these “dark stars” from ordinary black holes and other compact objects like neutron stars. I will also discuss some new techniques in dark matter direct detection that could facilitate searches in the sub-GeV mass region.

I will discuss how one-dimensional interacting fermion systems, which in the low energy approximation are described by Luttinger liquid theory, can be reformulated as systems of weakly interacting particles with fractional charge and statistics. The approach is to use Landau's phenomenological approach to Fermi liquid theory, with quasiparticles interpreted as adiabatically dressed fermions. In an earlier publication the local charge carried by these excitations has been shown to be a fraction of the fermion charge. I will here focus on the statistics of the quasiparticles and show that by a change of momentum variables the Landau parameters of the generalized Fermi fluid can be transformed to zero. This change in interaction is compensated by a change of the Pauli exclusion, which is consistent with the interpretation of the quasiparticles as satisfying generalized exclusion statistics.
