Putin once casually said over dinner that he could destroy America in a half-hour or less

Posted by in category: futurism


In December 2011, Vladimir Putin, then Russia’s prime minister, was positioned to reclaim his role as Russia’s president in the March 2012 elections.

Fittingly, he hosted a lavish banquet at New Century, Moscow’s richest equestrian club, for members of the Valdai Club and distinguished academics and journalists from around the world.

Benchtop Black Holes Help Physicists Glimpse the Quantum Universe

Posted by in categories: cosmology, particle physics, quantum physics

A black hole is a physicist’s playground: A place where some of the most bizarre and fundamental concepts in physics can be observed and tested. However, there is currently no way to directly observe black holes in action; these bodies of matter don’t emit the sort of radiation, like light or X-rays, that telescopes are equipped to detect. Fortunately, physicists have figured out ways to imitate the conditions of a black hole in the lab—and in creating analogues of black holes, they are beginning to unravel some the most fascinating puzzles in physics.

Jeff Steinhauer, a researcher in the Physics Department of Technion-Israel Institute of Technology, recently caught the attention of the physics community when he announced that he had used an analogue black hole to confirm Stephen Hawking’s 1974 theory that black holes emit electromagnetic radiation, known as Hawking radiation. Hawking predicted that this radiation would be caused by the spontaneous creation of a particle-antiparticle pair at the event horizon, the point at the edge of a black hole beyond which nothing—not even light—can escape. Under the terms of Hawking’s theory, as one of the particles crosses the event horizon and is captured by the black hole, the other would be ejected into space. Steinhauer’s experiment was the first to exhibit the sort of spontaneous fluctuations that support Hawking’s calculations.

Physicists have cautioned that this experiment still doesn’t confirm the existence of Hawking radiation in astronomical black holes, as Steinhauer’s black hole isn’t exactly the same as one we might observe in space. It’s not yet physically possible to create the intense gravitational fields that form black holes. Instead, the analogue imitates a black hole’s ability to absorb light waves by using sound.

Whispering gallery-mode biosensors are worth shouting about

Posted by in categories: biotech/medical, particle physics

In early 2016 University Professor of Applied Physics Stephen Arnold earned a patent for his system for finding the size of one or more individual particles (such as nanoparticles) in real time using a microsphere’s whispering gallery modes.

Arnold and his team at Tandon’s MicroParticle PhotoPhysics Laboratory for BioPhotonics (MP3L) had generated excitement throughout the in 2012, when they created an ultra-sensitive biosensor capable of identifying the smallest single virus particles in solution.

Their technique was a major advance in a series of experiments to devise a diagnostic method sensitive enough to detect and a single virus particle in a doctor’s office or field clinic, without the need for special assay preparations or conditions. Normally, such assessment required the virus to be measured in the vacuum environment of an electron microscope, which added time, complexity and considerable cost.

High-efficiency THz nano-detectors

Posted by in category: nanotechnology

Mechanically stacked two-dimensional Van-der-Waals heterostructures have been engineered to devise Terahertz frequency nano-detectors by using a flake of black phosphorus (BP) trapped between two layers of hexagonal boron nitride (hBN).

An international collaboration between researchers from Italy, USA, France and Poland brought together the benefits of heterostructure architecture and the potential of 2D layered nanomaterials to build THz photon sensors that operate over the 0.3−0.65 THz range, at low temperatures, with excellent signal to noise ratio values. They accomplished this by reassembling the thin isolated atomic planes of hexagonal borum nitride (hBN) with a few layer phosphorene (black phosphorus (BP)) in mechanically stacked hBN/BP/hBN heterostructures.

Artificial semiconductor heterostructures have an important role in modern electronic and photonic technologies, due to their effectiveness for manipulation and control of carriers from the visible to the THz range. Even though they are incredibly versatile, they usually require challenging production procedures due to the need of clean and abrupt interfaces. These characteristics are a major challenge for having high-efficiency devices at room temperature like source, detectors or modulators, especially in the far-infrared. With the emergence of two-dimensional (2D) layered materials, like graphene and phosphorene, as reliable, flexible and versatile alternatives for detectors operating at THz with low signal to noise ratio, this challenge was finally overcome.
