Atoms
-
University of Oxford physicists have linked two atomic clocks through quantum entanglement for the first time. The feat can help make these clocks so precise that they begin to approach the fundamental limit of precision set by quantum mechanics.
-
Researchers at NIST have shown that a cloud of atoms can be used as a receiver to pick up video transmissions. The team demonstrated this “Atomic Television” by transmitting live video feed and even video games through the atoms to a monitor.
-
Researchers have developed a more precise design for "optical tweezers," using a metasurface lens studded with millions of tiny pillars which focus light to trap and manipulate individual atoms. It could pave the way for powerful quantum devices.
-
In what's being hailed as an important first for chemistry, scientists have developed a new technology that can selectively rearrange atomic bonds within a single molecule, which could open up exciting possibilities in molecular machinery.
-
Ice may seem pretty simple in our everyday experience, but it actually comes in at least 20 different forms. Scientists at UNLV have now discovered a new type of ice that may be found deep in the Earth’s mantle or on distant watery planets.
-
Researchers have demonstrated key tech that could help scale up quantum computers, creating a model with a record-breaking 512 qubits. The team combined atoms of two elements into an array, so atoms can be manipulated without disturbing their neighbors.
-
The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on Earth tick slower than those in space. Now researchers have measured time passing at different speeds across just one millimeter, the smallest distance yet.
-
The universe is governed by two sets of seemingly incompatible laws of physics – classical and quantum physics. MIT physicists have now observed the moment atoms switch from one to the other, as they form intriguing “quantum tornadoes.”
-
German physicists have recorded the coldest temperature ever – 38 trillionths of a degree above absolute zero. The experiment involved dropping quantum gas and switching a magnetic field on and off to bring its atoms to an almost complete standstill.
-
Antimatter is hard to study, not least because it annihilates any container you try to put it in. Now CERN physicists have developed a new antimatter trap that can cool samples in seconds, which could help unlock a fundamental mystery of the universe.
-
Dark matter should be all around us, but the stuff is frustratingly elusive. Now physicists at NIST have developed a new sensor that could help us detect certain hypothetical dark matter particles, using a two-dimensional quantum crystal.
-
Astronomers have counted the number of neutrons inside carbon atoms from 2.8 quadrillion km away. The team managed to measure the ratios of carbon isotopes in the atmosphere of an exoplanet for the first time, which can tell us about how it formed.
