As a quasi-member of the Interfaces and Correlated Electron systems (ICE) group from Hans Hilgenkamp I joined the ICE2UK-tour. Together with Marcel Hoek, who is also on the VICI project, I gave a talk in Bristol - the hometown of Nevill F. Mott! We couldn't resist, the talk is called 'Mott...

At this years edition of the annual Dutch Physics@FOM conference in Veldhoven I will present a poster entitled "Exciton condensation in strongly correlated electron bilayers". Actually, for the first time the poster will actually be about exciton condensation, the initial goal of my PhD...

On 9 September 2011 I was presenting my work on interlayer excitons (see this preprint) at the University of Utrecht in the so-called 'BEC group meeting' (that is: the groups of Henk Stoof, Rembert Duine and Cristiane de Morais Smith combined).

In Erice (a beautiful place in Sicily, Italy) both a summer school and a workshop was held about "Quantum Phenomena in Graphene, other Low-Dimensional Materials, and Optical Lattices". Needless to say I was there for the "other low-dimensional materials", with lectures on bilayer exciton...

At the Physics@FOM Veldhoven 2010 (January 19, 2010) conference I presented a poster with the title "How a Neutral and Massless Superfluid can still exhibit Flux Quantization" (pdf, 2.8 MB).

This year at the Dutch Research School for Theoretical Physics AIO/OIO School for Statistical Physics and Theory of Condensed Matter (aka the DRSTP SPTCM School 2011) I gave some introduction to the idea of linear spin-wave theory and how it can be applied to interlayer excitons. More information...

This years contribution to the annual FOM meeting in Veldhoven is a poster entitled "Exciton motion in strongly correlated heterostructures" (PDF, 700 kB). It was a combined poster with my collaborators from Twente (Marcel Hoek, Francesco Coneri and Hans Hilgenkamp), who were responsible for the...

Today Kai Wu and I gave a presentation at Jan Zaanen's group meeting called the "Stripe Club". Our presentation was named "The motion of a single exciton in a bilayer quantum antiferromagnet" (PDF, 1.9 MB). In summary: we developed a spin wave theory for the bilayer Heisenberg model in order to...

My colleagues at the Twente University and me together presented a poster at the MESA+ Institute for Nanotechnology Meeting 2010 held in Enschede at 14 September. The title of our poster was "Bose-Einstein condensation of excitons in oxide heterostructures" and can be downloaded (3.7 MB).

Last week at the Casimir Spring School 2010 I was invited to give a talk on my work on 'Flux Quantization in Double Layer Exciton Superfluids'. With this talk I was awarded the prize for best oral presentation! :) You can download the presentation here in Powerpoint-format. Note that this talk is...
