Novel Carbon Nanotube Mechanical Resonator May Enable Exciting Quantum Systems

In a recent paper published in Nature Nanotechnology, Joel Moser and ICFO colleagues of the NanoOptoMechanics research group led by Prof. Adrian Bachtold, together with Marc Dykman (Michigan University), report on an experiment in which a carbon nanotube mechanical resonator exhibits quality factors of up to 5 million, 30 times better than the best quality factors measured in nanotubes to date.

U.Va.’s Accomplished Faculty Researchers Named as Distinguished Scientists

Two of the University of Virginia’s most accomplished faculty researchers – physicist Brad Cox and astronomer John Hawley – have been selected as 2014 Distinguished Scientists.

Researchers Solve One of the Most Famous Problems in Quantum Information Physics

Since 1999, the conjecture by Asher Peres, who invented quantum teleportation, has piqued the interest of many scientists in the field. According to his hypothesis, the weakest form of quantum entanglement can never result in the strongest manifestation of the phenomenon.

Scientists Demonstrate Practicality of Plasma Wakefield Acceleration

Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los Angeles have shown that a promising technique for accelerating electrons on waves of plasma is efficient enough to power a new generation of shorter, more economical accelerators. This could greatly expand their use in areas such as medicine, national security, industry and high-energy physics research.

MIT’s QEG on a Mission to Harness Quantum Properties of Matter

MIT’s Quantum Engineering Group (QEG) has a challenging but potentially world-changing mission: to harness the quantum properties of matter for use in information technology, metrology, defense, healthcare, and many other fields.

Gluons Contribute to Proton Spin

Results from experiments at the Relativistic Heavy Ion Collider (RHIC), a particle collider located at the U.S. Department of Energy’s Brookhaven National Laboratory, reveal new insights about how quarks and gluons, the subatomic building blocks of protons, contribute to the proton’s intrinsic angular momentum, a property more commonly known as “spin.” Specifically, the findings show for the first time that gluons make a significant contribution to proton spin, and that transient “sea quarks”—which form primarily when gluons split—also play a role.

Dark Matter Could be Made of Macroscopic Objects

The physics community has spent three decades searching for and finding no evidence that dark matter is made of tiny exotic particles. Case Western Reserve University theoretical physicists suggest researchers consider looking for candidates more in the ordinary realm and, well, more massive.

Structural Disorder Can Counteract Thermal Disorder and Lower Overall System Disorder

If you took the junk from the back of your closet and combined it with the dirty laundry already on your floor, you would have an even bigger mess. While this principle will likely always hold true for our bedrooms, it turns out that in certain situations, combining messes can actually reduce the disorder of the whole. An international team of researchers from Slovenia and Iran has identified a set of conditions in which adding disorder to a system makes it more orderly. This behavior is known as antifragility, a concept introduced recently to describe similar phenomena in statistics, economics and social science.

Study Suggests Equivalence Between Generalised Casimir Forces and Weak Nuclear Interaction Forces

A new theoretical work establishes a long-sought-after connection between nuclear particles and electromagnetic theories. Its findings suggest that there is an equivalence between generalised Casimir forces and those that are referred to as weak nuclear interactions between protons and neutrons.
