In quantum physics, Rydberg excitons with high principal value can exhibit strong dipole-dipole interactions. However, polaritons (quasiparticles) with an excitonic constituent in an excited state, known as Rydberg exciton ...
Understanding how particles behave at the twilight zone between the macro and the quantum world gives us access to fascinating phenomena—interesting from both the fundamental and application-oriented physics perspectives. ...
One problem in dealing with weapons of mass destruction is that they are well hidden. The key to finding them may be to change the methods we use to look. One such method is taking shape in a lab in the basement of Small ...
Besides solids, liquids and gases, more exotic states of matter can be generated in specific materials under special conditions. Such states are of great interest to physicists because they provide a deeper understanding ...
Supersolids, solid materials with superfluid properties (i.e., in which a substance can flow with zero viscosity), have recently become the focus of numerous physics studies. Supersolids are paradoxical phases of matter in ...
Sometimes in shallow water, a type of wave can form that is much more stable than ordinary waves. Called solitons, these phenomena emerge as solitary waves and can travel long distances while maintaining their shape and speed, ...
Generally, matter exists in three distinct forms: as a solid, a liquid or a gas. Past physics research, however, has unveiled other curious states of matter, one of which is supersolidity. In a supersolid state, particles ...
There are two sound velocities in a Bose-Einstein condensate. In addition to the normal sound propagation there is second sound, which is a quantum phenomenon. Scientists in Ludwig Mathey's group from the University of Hamburg ...
Two Australian studies published this week offer the first proof of a 70-year-old theory of turbulence.
In conventional imaging methods, a beam of photons (or other particles) is reflected off the object to be imaged. After the beam travels to a detector, the information gathered there is used to create a photograph or other ...
