I will report on dynamical magnetic susceptibility measurements of
both bulk and thin film samples of the spin glass Copper Manganese.
By studying the Thermoremanent Magnetization (TRM) of multi-layer thin
films of various thicknesses, we are able to show the maximum energy
barrier encountered during correlated spin flip transitions is cut off
by the thickness of the film and is independent of temperature. The
distribution of energy barriers is shown to follow from a hierarchical

Christopher Warren of the Department of Physics and Astronomy is presenting his thesis:

Towards Analog Quantum Simulation of Lattice Gauge Fields

Christopher is supervised by IQC faculty member Christopher Wilson.

Evan Meyer-Scott, Universität Paderborn 

I will present a realization of a great photon pair source based on parametric down-conversion, and discuss a not-so-great limit to the performance of photon pair sources in general. The former is a fully fiber-coupled waveguide pair source with 46% raw heralding efficiency, and no optical alignment required. The latter restricts the achievable heralding efficiency, when spectrally filtering the photons to increase the purity.
