Prof Joseph talked about Hyperbolic lattices which are a new form of synthetic quantum matter in which particles effectively hop on a discrete tiling of two-dimensional hyperbolic space, a non-Euclidean space of negative curvature. Hyperbolic tilings were studied by the geometer H.S.M. Coxeter and...

Dr. Robert-Jan Slager covered a selection of our recent work on topological characterizations in a rather colloquial style. In particular, he reviewed how constraints on symmetry eigenvalues can directly be linked to topological invariants, reproducing involved K-theory evaluations from a simple...

Our recent publication on long-range dipole-dipole interactions has featured as an online cover in Nano Letters . The paper shows that unique hybrid plasmonic lattice modes mediate dipole-dipole interactions between two different types of molecules over separation distances of ~800 nm. This is in...

In the given talk, Prof. Naik spoke about quantum materials possessing a complex energy landscape arising from the competition between many microscopic processes. A stimulus such as light can tip the delicate balance between these competing processes resulting in novel optical phenomena...

Excited to announce that our work on “Observation and control of Casimir effects in a sphere-plate sphere system” is published in Nature . Here, we experimentally demonstrate an object under the Casimir force exerted by two other objects simultaneously. Using our unique sphere-plate-sphere Casimir...
