Record measurement of extremely small magnetic fields
Researchers at the research center QUANTOP at the Niels Bohr Institute at the University of Copenhagen (Denmark) have constructed an atomic magnetometer, which has achieved the highest sensitivity allowed ...
A new class of electron interactions in quantum systems
Physicists at the University of New South Wales have observed a new kind of interaction that can arise between electrons in a single-atom silicon transistor.
Michelson-Morley experiment for electrons: Quantum-information techniques used to explore fundamental physics
A new experiment conducted at the University of California at Berkeley used quantum information techniques for a precision test of a cornerstone principle of physics, namely Lorentz invariance. This precept ...
Physicists get an up-close look at synthetic quantum materials
(PhysOrg.com) -- Physicists at Harvard University have, for the first time, tracked individual atoms in a gas cooled to extreme temperatures as the particles reorganized into a crystal, a process driven by ...
New technique excites atoms and molecules using pulsed laser
The best method to obtain the most precise information on the inner structure of atoms and molecules is to excite them by means of resonant laser light. Unfortunately, just this laser light (above a certain ...
Researcher studies the universe through quantum electrodynamics
(PhysOrg.com) -- Fundamental constants, such as the standards for length and mass, are a given in our society. However, research has shown that these constants might be changing slightly with the expansion of the universe.
Highly charged ions: Multiply-ionized atoms for clocks, qubits, and constants
The world is mostly neutral. That is, most of the atoms in our environment are electrically neutral. The number of electrons in the outer parts of atoms equals the number of protons at the centers of atoms. ...
Quantum microscope for living biology
(Phys.org)—A team of Australian scientists has developed a powerful microscope using the laws of quantum mechanics to probe the inner workings of living cells.
Physicists confine electrons inside nano-pyramids
(Phys.org)—Quantum dots are nanostructures of semiconducting materials that behave a lot like single atoms and are very easy to produce. Given their special properties, researchers see huge potential for ...
Researchers devise a means to control chemical reactions in individual atoms
Physicists calculate how to make atomic clocks super-accurate
(PhysOrg.com) -- When it comes to atomic clocks, every second counts. In fact, according to Marianna Safronova, every quintillionth of a second counts.
