Proton dripping tests a fundamental force in nature

(PhysOrg.com) -- Like gravity, the strong interaction is a fundamental force of nature. It is the essential "glue" that holds atomic nuclei—composed of protons and neutrons— together to form atoms, the building ...

Laser-driving of semimetals allows creating novel quasiparticle states

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity to observe particle properties that have no realization in elementary ...

Extremely rare Higgs boson decay process spotted

The Higgs boson reached overnight fame in 2012 when it was finally discovered in a jumble of other particles generated at CERN's Large Hadron Collider (LHC) in Geneva, Switzerland. The discovery was monumental because the ...

Physicists predict new state of matter

A researcher with the Department of Electrodynamics of Complex Systems and Nanophotonics, Alexander Rozhkov, has presented theoretical calculations which indicate the possible existence of fermionic matter in apreviously ...

Experiment tests underpinnings of quantum field theory, Bose-Einstein statistics of photons

(PhysOrg.com) -- Of all the assumptions underlying quantum mechanics and the theory that describes how particles interact at the most elementary level, perhaps the most basic is that particles are either bosons or fermions. ...

Physicists capture the sound of a 'perfect' fluid

For some, the sound of a "perfect flow" might be the gentle lapping of a forest brook or perhaps the tinkling of water poured from a pitcher. For physicists, a perfect flow is more specific, referring to a fluid that flows ...

One kind of supersymmetry shown to emerge naturally

(Phys.org) —UC Santa Barbara physicist Tarun Grover has provided definitive mathematical evidence for supersymmetry in a condensed matter system. Sought after in the realm of subatomic particles by physicists for several ...

Weyl goes chiral

Quasiparticles that behave like massless fermions, known as Weyl fermions, have been at the center of a string of exciting findings in condensed matter physics in recent years. The group of physicist Sebastian Huber at ETH ...

Quantum system virtually cooled to half of its actual temperature

Physicists have developed a quantum simulation method that can "virtually cool" an experimental quantum system to a fraction of its actual temperature. The method could potentially allow access to extremely low-temperature ...
