Researchers from University Jena, the University of California Berkeley and the Institut Polytechnique de Paris use intense laser light in the XUV spectrum to generate second harmonics on a laboratory scale. As the team writes in Science Advances, they were able to achieve this effect for the first time with a laser source on a laboratory scale and thus investigate the surface of a titanium sample down to the atomic level.
Date Time Current trend reversed The demonstration that a tiny cloud of atoms can be turned from a heat engine into a cooler by cranking up the interactions between the particles provides both deep fundamental insight and a possible template for more efficient thermoelectric devices. Artistic impression of the experiment in which Häusler and colleagues first heat one of two quantum-gas clouds and then connect them with a two-dimensional channel, such that they can equilibrate.

Image Credit: Marko Aliaksandr/Shutterstock.com Semiconductors are a widely used class of materials with electrical conductivities that fall between that of conductors and insulators. What has made doped versions of these materials the cornerstone of modern electronics is their ability to control the flow of electrons as part of a circuit, switching on and off as required, with a minimal physical device footprint. Controlling the flow of electrons is not the only interesting application of semiconductor materials. Some semiconducting materials can be used to either convert electricity into l...

Bangalore Scientists Discover New State Of Materials Useful To Create Controllable Quantum Technologies by Swarajya Staff - Mar 16, 2021 11:53 AM A representative image (Pic Via Honeywell website) Scientists have discovered a new exotic, strange state of materials in contact with an environment that alters its physical properties in the presence of an electromagnetic field, leading to better quantum technologies, which are tunable and controllable as per the user requirements. Dibyendu Roy, Associate Professor, and his group from Raman Research Institute (RRI) Bangalore, an autonomous institu...
