Quantum jumps are usually regarded to be instantaneous. However, new measurement methods are so precise that it has now become possible to observe such a process and to measure its duration precisely -- for example the famous 'photoelectric effect', first described by Albert Einstein.
Fundamental research: FLEET study of ultracold atomic gases at Swinburne University of Technology finds quantum anomaly, strongly interacting particles breaking classical symmetry in a 2D Fermi gas. Out today in Physical Review Letters.
RUDN University researchers have developed a mathematical method that allowed to solve the quantum Coulomb three body problem for bound states with high accuracy. They also showed that previous calculations performed by a group of Japanese scientists is incorrect. The work will help to calculate the trajectories of quantum particles motion in space accurately. Its results will be useful in solving fundamental problems of physics. The paper was published in the journal Physical Review A.
Physicists from RUDN, JINR (Dubna), and the University of Hamburg (Germany) developed a mathematical model for describing physical processes in hybrid systems that consists of atoms and ions cooled down to temperatures close to absolute zero. Such systems might be used in the quantum computer -- a device with exceptional calculation speed. The results of the study were presented at the 22nd International Conference on Few-Body Systems in Physics in Caen (France) in July 9-13, 2018.
An international team of researchers led by Princeton physicist Zahid Hasan has discovered a novel quantum state of matter whose symmetry can be manipulated at will by an external magnetic field. The methods demonstrated in a series of experiments could be useful for exploring materials for next-generation nano- or quantum technologies.
A system made of just a handful of particles acts just like larger systems, allowing scientists to study quantum behavior more easily.
Embargoed release reports new method for reducing instabilities in fusion plasmas without triggering fresh problem.
Physicists at the University of Bath have discovered how to manipulate and control individual molecules for a millionth of a billionth of a second, after being intrigued by some seemingly odd results.
Physicists employ a version of Maxwell's demon to reduce entropy in a three-dimensional lattice of super-cooled, laser-trapped atoms, a process that could help speed progress toward creating quantum computers.
Experts in the Nanoscale and Microscale Research Centre (nmRC) at the University of Nottingham have taken a first peak into the private life of atomic clusters.
