In our three-dimensional space, elementary particles neatly filter into either bosons or fermions. But in lower dimensions, that distinction gets a bit murky.

“The theoretical framework we developed explains how quasiparticles emerge in systems with an extremely heavy impurity, ...

Strong interactions between particles in physical systems can result in various highly correlated ground states. These states and the strong correlations underpinning them have been extensively ...

Physicists at the Delft University of Technology, Netherlands, have achieved a milestone that might soon revolutionize the world of quantum computing, quantum physics, and perhaps shed new light on ...

In recent years physicists have realized that fermions can exhibit superfluid behaviour because of their ability to pair up at very low temperatures. Now a US group has shown that if a mixture of ...

Evidence for the existence of particles called Weyl fermions in two very different solid materials has been found by three independent groups of physicists. First predicted in 1929, Weyl fermions also ...

Fermions tend to avoid each other and cannot "travel" in close proximity. Demonstrated by a team at the Institut d'optique in France, this result is described in detail in the January 25, 2007 issue ...

The combined paired and periodic structure of the bubble phase of composite fermions represents an entirely new family of matter. WEST LAFAYETTE, Ind. – Like finding a hidden world, physicists dialing ...

Some people like company. Others prefer to be alone. The same holds true for the particles that constitute the matter around us: Some, called bosons, like to act in unison with others. Others, called ...

Fermions tend to avoid each other and cannot “travel” in close proximity. Demonstrated by a team at the Institut d’optique (CNRS/Université Paris 11, Orsay-Palaiseau), this result is described in ...

Inside materials, the interactions between groups of electrons and atoms in the crystal lattice can give rise to a variety of interesting phenomena. Their collective behavior, especially at low ...

Today, quantum optical experiments provide methods to prove the rules that have been thought of and pressed into elegant mathematical equations in those days, say scientists. The microcosm is governed ...
