The origin and nature of the dark matter in the Universe is one of the most pressing questions in fundamental physics. The combination of particle physics and cosmology has proven to be a successful avenue leading to the well-established theory of big bang nucleosynthesis that explains the primordial abundances of light elements. In the similar manner an extrapolation to even earlier times in the Universe has led to the WIMP (Weakly Interacting Massive Particle) freeze-out paradigm - one of the best motivated explanations of the dark matter relic abundance measured today. However, despite an enormous experimental effort no conclusive hint for WIMPs has been found, putting pressure on the WIMP dark matter explanation. In this talk we examine new avenues beyond the standard WIMP picture. We show that scrutinizing the well-known co-annihilation scenario and dropping the commonly made assumption of chemical equilibrium between co-annihilating partners offers new phenomenological possibilities. By solving the full coupled set of Boltzmann equations we find solutions that accommodate the measured dark matter density while requiring very small couplings that are in accordance with current null-results in WIMP searches.

I will give an overview over the potential impact of (recent and future) observations of gravitational waves on cosmology and particle physics. This ranges from the measurement of the equation of state of QCD and the Hubble expansion parameter to (black hole) dark matter and inflation. I will dwell a little bit more on the connection to cosmological phase transitions that are mostly interesting to future space-based gravitational wave observatories.

A seminar with guest lectures from Uppsala University
Wednesday, October 25th, 2017 Lille fysiske auditorium, 2 etasje vest, Fysikkbygningen
What are the unique competencies of a good physics teacher? How do university physics (science) departments accommodate student teachers in their courses? Which values and expectations characterise physics department culture – and how do these interact with student teachers’ aspirations, identity and learning? Who is the ‘implied student’ that teachers or lecturers target their teaching at, and what happens when the ‘implied student’ differs from the real students?

Utvikling av stabilisert plattform for hydroakustiske transducere
Ankit Beniwal, University of Adelaide
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.
