Platinum selenaide is a two-dimensional material formed by the layered combination of platinum (Pt) and selenium (Se). Its ...
The efficiency of quantum computers, sensors and other applications often relies on the properties of electrons, including ...
Once the Fermi gas had reached the quantum regime, we obtained information about it by turning the magnetic trap off, allowing the gas to expand and measuring the shadow of the gas cast by a laser.
Atoms move more slowly than light, so a quantum-tornado sensor would be much more sensitive—possibly even sensitive enough to measure slight changes in the Earth's rotation. DOI: Nature, 2022 ...
1D quantum gases often behave counterintuitively. For instance, unlike a 3D gas, the interactions between the atoms become stronger as the density of the gas is reduced. Tilman Esslinger and ...
The other was a strongly interacting two-dimensional Fermi gas using lithium atoms. First, they allowed a cloud of atoms to interact in a loose trap formed by a laser beam.
The latest in this line of work is an effort by chemists Henri J. Suominen and Adam Kirrander, who propose using X-ray lasers to study the electron dynamics in noble gas atoms.
Scientists have successfully trapped atoms of krypton (Kr), a noble gas, inside a carbon nanotube to form a one-dimensional gas. Scientists used advanced transmission electron microscopy (TEM ...
Scientists have succeeded in the stabilization and direct imaging of small clusters of noble gas atoms at room temperature. This achievement opens up exciting possibilities for fundamental ...
Chemically, carbon dioxide is incredibly simple – it is just one carbon atom linked with two oxygen atoms. Together they create a colorless gas that makes up just a tiny fraction of the Earth's ...
But many gases with three or more atoms do not. Greenhouse gases also have a wide range of potency. Some exert a warming effect several thousand times greater even than that of carbon dioxide.
The first 117 elements on the periodic table were relatively normal. Then along came element 118. Oganesson, named for Russian physicist Yuri Oganessian (SN: 1/21/17, p. 16), is the heaviest ...
