Time and place: May 24, 2017 12:30 PM - 2:00 PM, Ø467

Kjetil Børkje, University College of Southeast Norway

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.

Jon Magne Leinaas, FI

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.

Gas in between galaxies produces a forest of absorption lines in the spectra of bright objects such as distant quasars. This "Lyman-alpha forest" arises due to absorption by a sprinkling of neutral hydrogen in the otherwise highly ionised intergalactic gas, with many  lines forming in mildly over dense, or indeed under dense intervening structures. These modest fluctuations can be simulated quite accurately, and comparing mock spectra to the exquisitely high resolution and high signal-to-noise observed spectra allows tight constraints on the nature of the absorbers.

In this talk, I will concentrate on what such as comparison tells up about the temperature and ionisation state of the gas, and explain how these measurements can also put tight constraints on any free streaming due to warm dark matter.
