Scanning tunneling microscopy experiments in a high-temperature superconductor probe the temperature evolution of local electronic states, revealing that regions in the sample exhibiting weak superconductivity can persist to elevated temperatures if they are surrounded by regions of strong superconductivity.
The transmission of light through a disordered medium is described in microscopic detail by a high-dimensional matrix. Researchers have now measured this transmission matrix directly, providing a new approach to control light propagation.
Experiments now quantitatively confirm the standard model of electrokinetics, in which electric fields drive the flow of electrolytes, potentially leading to better sensors and biomedical diagnostic devices.
The combination of trivial and topological band insulators with a superconductor is bringing anyons—particles that behave neither according to purely Bose nor Fermi statistics—into the three-dimensional world.
