Researchers putting a freeze on oscillator vibrations
University of Oregon physicists have successfully landed a one-two punch on a tiny glass sphere, refrigerating it in liquid helium and then dosing its perimeter with a laser beam, to bring its naturally occurring mechanical vibrations to a near standstill.   view more (2009-06-18)

Evidence of macroscopic quantum tunneling detected in nanowires
A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is able to "tunnel" as a pack from a state with a higher electrical current to one with a notably lower current, providing more... view more...

Physicists offer new theory for iron compounds
An international team of physicists from the United States and China this week offered a new theory to both explain and predict the complex quantum behavior of a new class of high-temperature superconductors.   view more (2009-03-13)

Hidden order found in a quantum spin liquid
An international team, including scientists from the London Center for Nanotechnology, has detected a hidden magnetic "quantum order" that extends over chains of 100 atoms in a ceramic without classical magnetism. The findings, which are published today, July 26, by Science, have implications for the design of devices and materials for... view more... (2007-07-27)

Quantum analog of Ulam's conjecture can guide molecules, reactions
Like navigating spacecraft through the solar system by means of gravity and small propulsive bursts, researchers can guide atoms, molecules and chemical reactions by utilizing the forces that bind nuclei and electrons into molecules (analogous to gravity) and by using light for propulsion.   view more (2007-08-08)

Quantum physics pioneer honoured in Bristol
According to a current magazine advertisement, quantum physics is getting easier. It’s doubtful whether most of the population would agree with this. However, today (12 December) in Bristol, one of the pioneers of quantum physics, Noble prize-winner Paul Dirac, is being commemorated in two separate ceremonies. The first is in the Bishopston... view more... (2000-12-08)

U of T physicists are first to 'squeeze' light to quantum limit
A team of University of Toronto physicists have demonstrated a new technique to squeeze light to the fundamental quantum limit, a finding that has potential applications for high-precision measurement, next-generation atomic clocks, novel quantum computing and our most fundamental understanding of the universe.   view more (2009-01-07)
