Chirality-assisted lateral momentum transfer for bidirectional enantioselective separation

Phys.org   -   Scientific News Websites

Light carrying photon momentum can push and pull microparticles through momentum exchange. This momentum exchange process generates optical forces, which either attracts (conventional optical tweezers), pushes (radiation force) or pulls (pulling f...

Topological insulators feature lossless conduction at the edges

Phys.org   -   Scientific News Websites

Atomically thin layers of the semimetal tungsten ditelluride conduct electricity losslessly along narrow, one-dimensional channels at the crystal edges. The material is therefore a second-order topological insulator. By obtaining experimental proo...
