The Dynamics Of Walking Droplets
2013-10-02 04:42:48

[ Watch the Video: Strange Behavior Of Bouncing Drops ] April Flowers for redOrbit.com - Your Universe Online It is possible to make a tiny droplet of fluid levitate on the surface of a vibrating bath, walking or bouncing across, according to a research team led by Yves Couder at the Université Paris Diderot. The droplets, propelled by their own wave fields, exhibit certain features previously thought to be exclusive to the microscopic quantum realm. This quantum-like behavior...

Creating Matter That Behaves Like Luke Skywalker's Light Saber
2013-09-26 07:51:56

redOrbit Staff & Wire Reports - Your Universe Online Scientists from Harvard University and the Massachusetts Institute of Technology (MIT) have joined forces to create a never-before-seen form of matter that is said to behave like the legendary light sabers of Star Wars fame. Harvard physics professor Mikhail Lukin, MIT physics professor Vladan Vuletic and their colleagues were able to coax photons into binding together to form what they describe as “photonic molecules.” In...

Physics That Connect The Classical Temperature To The Quantum World
2013-09-09 12:00:32

Vienna University of Technology How does a classical temperature form in the quantum world? An experiment at the Vienna University of Technology has directly observed the emergence and the spreading of a temperature in a quantum system. Remarkably, the quantum properties are lost, even though the quantum system is completely isolated and not connected to the outside world. The experimental results are being published in this week’s issue of “Nature Physics”. Quantum and Classical...

New 'Quantum Key Distribution' System Safeguards Secrets, Works In The Real World
2013-09-04 13:00:43

University of Calgary University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets. The team's research – published in the journal Physical Review Letters back-to-back with similar work by a group from Hefei, China – also removes a big obstacle to realizing future applications of quantum communication, including a fully functional quantum network. "I hope...

Quantum Inverted Pendulum
2013-08-28 08:18:43

Georgia Institute of Technology A simple pendulum has two equilibrium points: hanging in the "down" position and perfectly inverted in the "up" position. While the "down" position is a stable equilibrium, the inverted position is definitely not stable. Any infinitesimal deviation from perfectly inverted is enough to cause the pendulum to eventually swing down. It has been known for more than 100 years, though, that an inverted pendulum can be stabilized by vibrating the pivot point....

One of the many counterintuitive and bizarre insights of quantum mechanics is that even in a vacuum—what many of us think of as an empty void—all is not completely still. Low levels of noise, known as quantum fluctuations, are always present. Always, that is, unless you can pull off a quantum trick. And that's just what a team led by researchers at the California Institute of Technology (Caltech) has done. The group has engineered a miniature silicon system...

MIT researchers expand the range of quantum behaviors that can be replicated in fluidic systems, offering a new perspective on wave-particle duality In the early days of quantum physics, in an attempt to explain the wavelike behavior of quantum particles, the French physicist Louis de Broglie proposed what he called a "pilot wave" theory. According to de Broglie, moving particles — such as electrons, or the photons in a beam of light — are borne along on...

Quantum research pushes boundary by testing micro theory for macro objects Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects. Researchers at the University of Calgary recently made a significant step forward in this direction by creating a large system that is in two substantially different states at the same time. Until this point,...

Detection Of Single Photons Through Quantum Entanglement
2013-07-08 10:47:20

University of Innsbruck Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition and temperature of the sun's atmosphere. Today we are able to gain information about diverse objects through light measurements in a similar way. Because often very little light needs to be detected for this, physicists are looking for ever more sensitive...

Niels Henrik David Bohr (October 7, 1885 - November 18, 1962) was a Danish physicist. He made essential contributions to understanding atom structure and quantum mechanics. Born in Copenhagen, Denmark to Christian Bohr and Ellen Adler, Bohr got his doctorate at Copenhagen University in 1911. He then studied under Ernest Rutherford in Manchester, England. Based on Rutherford's theories, Bohr published his Bohr model about atom structure in 1913, introducing the theory of electrons...

  • A 'bachelor seal'; a young male seal which is prevented from mating by its herd's older males (mated bulls defending their territory).
This comes from the Russian word for 'bachelors.'
