When Fock meets Landau: Topology in atom-photon interactions

Since the discovery of the quantum Hall effect, topological phases of electrons have become a major research area in condensed matter physics. Many topological phases are predicted in lattices with specific engineering of ...

A new 'golden' age for electronics?

One way that heat damages electronic equipment is it makes components expand at different rates, resulting in forces that cause micro-cracking and distortion. Plastic components and circuit boards are particularly prone to ...

Physicists made crystal lattice from polaritons

An international research team produced an analog of a solid-body crystal lattice from polaritons, hybrid photon-electron quasiparticles. In the resulting polariton lattice, the energy of certain particles does not depend ...

Liquid crystals open new route to planar optical elements

Researchers at Osaka University developed a technology to control the light wavefront reflected from a cholesteric liquid crystal - a liquid crystal phase with a helical structure. Although known for their ability to Bragg-reflect ...

Watching protein crystal nucleation in real time

A major hurdle in structural biology and pharmacology is growing crystals to determine the structure of the biomolecules and pharmaceuticals under study. Researchers at the University of Tübingen, working with colleagues ...
