Are virtual particles really constantly popping in and out of existence?

Are virtual particles really constantly popping in and out of existence?  Virtual particles are indeed real particles. Quantum theory predicts that every particle spends some time as a combination of other particles in all possible ways. These predictions are very well understood and tested. Quantum mechanics allows, and indeed requires, temporary violations of conservation of energy, so one particle can become a pair of heavier particles (the so-called virtual particles), which quickly rejoin into the original particle as if they had never been there. If that were all that occurred we would still be confident that it was a real effect because it is an intrinsic part of quantum mechanics, which is extremely well tested, and is a complete and tightly woven theory--if any part of it were wrong the whole structure would collapse. But while the virtual particles are briefly part of our world they can interact with other particles, and that leads to a number of tests of the q...

Quasar outflows may create molecules, as well as destroying them

Quasar outflows may create molecules, as well as destroying them!!! Some types of molecules could form in powerful quasar winds that would ordinarily blast molecules to bits, according to astrophysicists in the US. Their findings, based on computer simulations of the outflows, show that feedback in active galaxies is more complex than had been thought. Quasars are powered by spiralling discs of gas around a supermassive black hole. The gas in the disc is at billions of degrees and drives powerful winds of radiation that move out into the host galaxy at hundreds of kilometres per second, sweeping up molecular gas that could otherwise be used for star formation. Under normal circumstances, this molecular gas should be blasted into its atomic constituents by the outflow radiation. However, observations of quasars have revealed unexpected molecular gas, including carbon monoxide, hydroxyl and warm molecular hydrogen, in the outflows. Now  Alexander Richings  and  C...

A new state of matter discovered!!! (Rydberg Polarons)

S cientists have observed a new class of quantum matter at the very smallest scales in one of the coldest environments ever made. This discovery could pave the way for new technologies including innovations in superconductivity and other cutting-edge fields. The researchers examined the behavior of matter on the atomic and subatomic scales – known as “quantum matter” – where a large number of particles interact with each other. This latest discovery reveals a new state of quantum matter called a “Rydberg polaron,” a relatively giant particle containing many atoms that behaves in some ways like a single massive particle. The experiment, initiated by the theoretical work at the Institute for Theoretical Atomic Molecular and Optical Physics (ITAMP) at the Harvard-Smithsonian Center for Astrophysics ( CfA ) and Harvard Physics, was performed in the laboratory of Thomas Killian at Rice University, where the electrons were given so much energy, on the verge of being pulled away from ...

Some meteorites contain superconducting bits

Some meteorites contain superconducting bits In the search for new superconductors, scientists are leaving no stone — and no meteorite — unturned. A team of physicists has now found the unusual materials, famous for their ability to conduct electricity without resistance, within two space rocks. The discovery implies that small amounts of superconducting materials might be relatively common in meteorites, James Wampler of the University of California, San Diego, said March 6 at a meeting of the American Physical Society. While the superconducting materials found weren’t new to science, additional interplanetary interlopers might harbor new, more technologically appealing varieties of superconductors, the researchers suggest. Superconductors could potentially beget new, energy-saving technologies, but they have one fatal flaw: They require very cold temperatures to function, making them impractical for most uses. So scientists are  on the hunt for new types of supercond...

Precision Qubits Achieve Major Milestone

Precision Qubits Achieve Major Quantum Computing Milestone The unique Australian approach of creating quantum bits from precisely positioned individual atoms in silicon is reaping major rewards, with UNSW Sydney-led scientists showing for the first time that they can make two of these atom qubits “talk” to each other. The team – led by UNSW Professor Michelle Simmons, Director of the Centre of Excellence for Quantum Computation and Communication Technology, or CQC2T – is the only group in the world that has the ability to see the exact position of their qubits in the solid state. Simmons’ team creates the atom qubits by precisely positioning and encapsulating individual phosphorus atoms within a silicon chip. Information is stored on the quantum spin of a single phosphorus electron. The team’s latest advance – the first observation of controllable interactions between two of these qubits – is published in the journal  Nature Communications . It follows two other rece...
