A team of researchers working at Stanford University has extended the record for quantum superposition at the macroscopic level from one to 54 centimeters. In their paper published in the journal Nature, the team describes ...
The concept of temperature is critical in describing many physical phenomena, such as the transition from one phase of matter to another. Turn the temperature knob and interesting things can happen. But other knobs might ...
Particles can be classified as bosons or fermions. A defining characteristic of a boson is its ability to pile into a single quantum state with other bosons. Fermions are not allowed to do this. One broad impact of fermionic ...
For many years rubidium has been a workhorse in the investigation of ultracold atoms. Now JQI scientists are using Rb to cool another species, ytterbium, an element prized for its possible use in advanced optical clocks ...
Physicists from Rice University and the University of Texas at Austin have found a new recipe for using intense lasers to create positrons—the antiparticle of electrons—in record numbers and density.
If you take certain atoms and make them almost as cold as they possibly can be, the atoms will fuse into a collective low-energy quantum state called a Bose-Einstein condensate. In 1968 physicist Herbert Fröhlich predicted ...
An international team of physicists has created a quantum billiards game to gain new insights into the fundamental physics of exceptional points.
Physicists have wondered in recent years if they could control how atoms interact using light. Now they know that they can, by demonstrating games of quantum billiards with unusual new rules.
JQI scientists have achieved a major milestone in simulating the dynamics of condensed-matter systems – such as the behavior of charged particles in semiconductors and other materials – through manipulation of carefully controlled ...
(Phys.org)—It was a big week for physics—a research team at MIT created a superfluid in a record-high magnetic field—a Bose-Einstein condensate—for a tenth of a second. And another team at MIT announced a new design that ...
