Binding together repelling atoms
Basic chemistry tells us that a bond between atoms can form if it is energetically more favorable for the atoms to stick together than staying apart. This fundamentally requires an attractive force between ...
Astronomers gain new knowledge about early galaxies
The early galaxies of the universe were very different from today's galaxies. Using new detailed studies carried out with the ESO Very Large Telescope and the Hubble Space Telescope, researchers, including ...
Shape from sound: New methods to probe the universe
(Phys.org) —As the universe expands, it is continually subjected to energy shifts, or "quantum fluctuations," that send out little pulses of "sound" into the fabric of spacetime. In fact, the universe is thought to have ...
Researchers demonstrate Heisenberg uncertainty principle at macro level
Does probability come from quantum physics?
(Phys.org)—Ever since Austrian scientist Erwin Schrodinger put his unfortunate cat in a box, his fellow physicists have been using something called quantum theory to explain and understand the nature of waves and particles.
Noise is not necessarily detrimental to quantum devices
The researches of the Aalto University and the University of Oulu have succeeded to simulate a phenomenon called motional averaging, which demonstrates that in certain conditions externally-induced fast fluctuations ...
Qubits that never interact could exhibit past-future entanglement
Neutrons uncover new density waves in fermion liquids
Scientists working at the Institut Laue-Langevin, one of the world's leading centres for neutron science, have carried out the first investigation of two-dimensional fermion liquids using neutron scattering, and discovered ...
Physicists search for new physics in primordial quantum fluctuations
A microscopic view on quantum fluctuations
(PhysOrg.com) -- Scientists at the Max Planck Institute of Quantum Optics achieve direct imaging of quantum fluctuations at absolute zero temperature.
Physicists move one step closer to quantum computer
Rice University physicists have created a tiny "electron superhighway" that could one day be useful for building a quantum computer, a new type of computer that will use quantum particles in place of the digital ...
Squeezed light from single atoms
(PhysOrg.com) -- Max Planck Institute of Quantum Optics scientists generate amplitude-squeezed light fields using single atoms trapped inside optical cavities.
Researchers take a step toward valleytronics
Valley-based electronics, also known as valleytronics, is one step closer to reality. Two researchers at the Naval Research Laboratory (NRL) have shown that the valley degree of freedom in graphene can be ...
Random numbers game with quantum dice
(PhysOrg.com) -- A simple device measures the quantum noise of vacuum fluctuations and generates true random numbers.
