Researchers Recreate Quantum Tunneling Effect for Sound Waves

When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even exist? Recently, researchers at Nanjing University in China created a material from polyethylene membranes that does exactly that.

Wavelike Quantum Behavior of Polariton Condensate at Room Temperature Demonstrated on Macroscopic Scale

For the first time, the wavelike behaviour of a room-temperature polariton condensate has been demonstrated in the laboratory on a macroscopic length scale. This significant development in the understanding and manipulation of quantum objects is the outcome of a collaboration between Professor Stéphane Kéna-Cohen of Polytechnique Montréal, Professor Stefan Maier and research associate Konstantinos Daskalakis of Imperial College London. Their work has been published in the prestigious journal Physical Review Letters.

Minute Transistor with Single Molecule and Few Atoms Created Using Scanning Tunneling Microscope

A team of physicists from the Paul-Drude-Institut für Festkörperelektronik (PDI) and the Freie Universität Berlin (FUB), Germany, the NTT Basic Research Laboratories (NTT-BRL), Japan, and the U.S. Naval Research Laboratory (NRL), United States, has used a scanning tunneling microscope to create a minute transistor consisting of a single molecule and a small number of atoms. The observed transistor action is markedly different from the conventionally expected behavior and could be important for future device technologies as well as for fundamental studies of electron transport in molecular nanostructures. The complete findings are published in the August 2015 issue of the journal Nature Physics.

Quantum Physics of Light Harvesting Could be a Delicate Interplay Between Vibrations and Electrons

Plants and bacteria make use of sunlight with remarkably high efficiency: nine out of ten absorbed light particles are being put to use in an ordinary bacterium. For years, it has been a pressing question of modern research whether or not effects from quantum physics are responsible for this outstanding performance of natural light harvesters.

NASA's Fermi Gamma-Ray Space Telescope Detects Brief Record-Setting Flare from 3C 279 Blazar

Five billion years ago, a great disturbance rocked a region near the monster black hole at the center of galaxy 3C 279. On June 14, the pulse of high-energy light produced by this event finally arrived at Earth, setting off detectors aboard NASA's Fermi Gamma-ray Space Telescope and other satellites. Astronomers around the world turned instruments toward the galaxy to observe this brief but record-setting flare in greater detail.

After Collision, Larger Galaxy Stops Smaller One from Making New Stars

When two different sized galaxies smash together, the larger galaxy stops the smaller one making new stars, according to a study of more than 20,000 merging galaxies.

Shaking Motion Excites Fast-Moving Magnetic Waves Emanating from Supermassive Black Hole

Fast-moving magnetic waves emanating from a distant supermassive black hole undulate like a whip whose handle is being shaken by a giant hand, according to a new study using data from the National Radio Astronomy Observatory's Very Long Baseline Array. Scientists used this instrument to explore the galaxy/black hole system known as BL Lacertae (BL Lac) in high resolution.

Super-Sized Black Hole Grew Much Faster Than Host Galaxy

Astronomers have spotted a super-sized black hole in the early universe that grew much faster than its host galaxy.

Black Holes Help to Keep Size of Galaxies in Check

It takes two plane flights and a 180-mile car ride to get from Princeton to one of the darkest places in the continental United States, the McDonald Observatory in West Texas. From this isolated spot, Jenny Greene looks out into the universe.

Hubble Captures Ghostly Shells of ESO 381-12 Galaxy

The ghostly shells of galaxy ESO 381-12 are captured here in a new image from the NASA/ESA Hubble Space Telescope, set against a backdrop of distant galaxies. The strikingly uneven structure and the clusters of stars that orbit around the galaxy suggest that ESO 381-12 may have been part of a dramatic collision sometime in its relatively recent past.
