A team of researchers from the University of Vienna and the Austrian Academy of Sciences (ÖAW) has introduced a novel technique to detect entanglement even in large-scale quantum systems. Here is how the technique works: After a quantum system has been generated in the laboratory, the scientists choose specific quantum measurements that are then applied to the system. The results of these measurements lead to either confirming or denying the presence of entanglement. The scientists’ confidence in the existence of entanglement grows exponentially with the number of individual detection events, namely copies of the quantum state. “It is somehow similar to asking certain ‘yes/no’ questions to the quantum...

An international research team led by Technische Universität Dresden (TU Dresden) has found a way to significantly boost OLED efficiency by extracting the trapped photons from OLEDs, which account for about 20% of the light particles that OLEDs generate. To free trapped photons from white OLEDs, the researchers implemented nanostructures produced by reactive ion etching on a polydimethylsiloxane (PDMS) surface. They were able to control the topography of these quasi-periodic nanostructures by tuning the pretreatment conditions of the PDMS and the reactive ion etching treatment recipes.

17:02 Phys.orgCould vacuum physics be revealed by laser-driven microbubbles?

A vacuum is generally thought to be nothing but empty space. But in fact, a vacuum is filled with virtual particle-antiparticle pairs of electrons and positrons that are continuously created and annihilated in unimaginably short time-scales.

16:39 Phys.orgMEMS-in-the-lens architecture for laser scanning microscopy

Laser-scanning microscopes can be miniaturized to image microenvironments in vivo via inclusion inside optical micromechanical system (MEMS) devices to replace the existing larger components. Multifunctional active optical devices are emerging components that support miniaturization for diffraction-limited performance with simpler optical system designs in optical devices. In a recent study, Tianbo Liu and a team of researchers in the departments of Electrical and Computer Engineering and Dermatology in the U.S. proposed a catadioptric (allowing both light reflection and refraction) microscope objective lens, featuring an integrated MEMS device to perform biaxial scanning, axial focus adjustment and control spherical aberration.

16:28 Improbable ResearchA look back at the 25th First Annual Ig Nobel Prize ceremony

The 25th First Annual Ig Nobel Prize ceremony, in the year 2015, was extra-memorable. Diane Kelly, reporting for Gizmodo, explained why: The 25th Ig Nobel Awards Were The Greatest Moment In The History of (Silly) Science For years, the Ig Nobel Awards have been famous for celebrating the most offbeat and ludicrous forms of scientific discovery. And last […]

15:29 Phys.orgDiscovering exoplanets with gravitational waves

In a recent paper in Nature Astronomy, researchers from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Potsdam and from the French Alternative Energies and Atomic Energy Commission (CEA) in Saclay, Paris suggest how the planned space-based gravitational-wave observatory LISA can detect exoplanets orbiting white dwarf binaries everywhere in the Milky Way and in the nearby Magellanic Clouds. This new method will overcome certain limitations of current electromagnetic detection techniques and might allow LISA to detect planets down to 50 Earth masses.

15:17 Phys.org3 sky surveys completed in preparation for Dark Energy Spectroscopic Instrument

It took three sky surveys—conducted at telescopes in two continents, covering one-third of the visible sky, and requiring almost 1,000 observing nights—to prepare for a new project that will create the largest 3-D map of the universe's galaxies and glean new insights about the universe's accelerating expansion.

Scientists have used an electron microscope to manipulate strongly bound materials with atomic precision. Since the instruments used are fully computerized, it is possible to show in a simulation how researchers actually use them. A simulation game has now also been released online, together with the latest research advance of silicon impurity manipulation in single-walled carbon nanotubes.
