Researchers create new Bose-Einstein condensate

Researchers at Aalto University, Finland, have created a Bose-Einstein condensate of light coupled with metal electrons, so-called surface plasmon polaritons. Nearly 100 years ago, Albert Einstein and Satyendra Nath Bose predicted that quantum mechanic…

Quantum shift shows itself in coupled light and matter

A team led by Rice University scientists used a unique combination of techniques to observe, for the first time, a condensed matter phenomenon about which others have only speculated. The research could aid in the development of quantum computers.

Quantum physicists achieve entanglement record

Entanglement is of central importance for the new quantum technologies of the 21st century. A German-Austrian research team is now presenting the largest entangled quantum register of individually controllable systems to date, consisting of a total of …

Finding order in disorder demonstrates a new state of matter

Physicists have identified a new state of matter whose structural order operates by rules more aligned with quantum mechanics than standard thermodynamic theory. In a classical material called artificial spin ice, which in certain phases appears disord…

A novel test bed for non-equilibrium many-body physics

The behavior of electrons in a material is typically difficult to predict. Novel insight comes now from experiments and simulations performed by a team led by ETH physicists who have studied electronic transport properties in a one-dimensional quantum …

New math bridges holography and twistor theory

The modern-day theoretical physicist faces a taxing uphill climb. “As we learn more, reality becomes ever more subtle; the absolute becomes relative, the fixed becomes dynamical, the definite is laden with uncertainty,” writes physicist Yasha Neiman.

Putting quantum scientists in the driver’s seat

Scientists at the Department of Energy’s Oak Ridge National Laboratory are conducting fundamental physics research that will lead to more control over mercurial quantum systems and materials. Their studies will enable advancements in quantum computing,…

Molecular prison forces diatomic inmates to cell floor

A team of scientists including Carnegie’s Tim Strobel and Venkata Bhadram now report unexpected quantum behavior of hydrogen molecules, H2, trapped within tiny cages made of organic molecules, demonstrating that the structure of the cage influences the…
