An acoustic cage for electrons

New concept for trapping and manipulating electrons with sound waves

16-Nov-2017 - The ability to trap and control electrons and other quasi-particles for the study of isolated single particles as well as many-body systems in a solid-state environment can be of major importance for understanding the behaviour of correlated electrons in technologically relevant materials. ...

Need entangled atoms?

Get 'Em FAST! with NIST's new patent-pending method

09-Nov-2017 - Physicists at the National Institute of Standards and Technology (NIST) have come up with a way to link a group of atoms' quantum mechanical properties among themselves far more quickly than is currently possible, potentially providing a tool for highly precise sensing and quantum computer ...

Correlated magnets made out of single atoms

Scientists observe antiferromagnetic correlations in one-dimensional fermionic quantum systems

04-Oct-2016 - Solid state physics offers a rich variety of intriguing phenomena, several of which are not yet fully understood. Experiments with fermionic atoms in optical lattices get very close to imitating the behaviour of electrons in solid state crystals, thus forming a well-controlled quantum simulator ...

Ultracold atoms in a "Rydberg-dress"

Scientists have developed a novel technique to let atoms interact over large distances

12-Aug-2016 - Many properties of our everyday world can be explained if atoms are thought of as small, solid marbles, which feel each other only if brought in direct contact with each other. The temperature of the air surrounding us, for example, is the result of uncountable, continuously occurring collisions ...

Atoms Chat Long Distance

11-Apr-2016 - In an international first, a research team of experimental physicists led by Francesca Ferlaino and theoretical physicists led by Peter Zoller has measured long-range magnetic interactions between ultracold particles confined in an optical lattice. Their work, published in Science, introduces a ...

A Quantum Pump for Ultracold Atoms

Scientists realize a dynamic version of the quantum Hall effect in optical superlattices

21-Dec-2015 - The transport of particles is usually induced by applying an external gradient to a system. More than 30 years ago, the Scottish physicist David Thouless predicted that a similar phenomenon should also occur in quantum mechanical systems, so called topological pumping. A group of researchers from ...
