A team of researchers has created a new, more precise algorithm for simulating particle interactions when a single impurity is introduced into a Fermi sea. The algorithm shows that when these ...

Pairing interaction appears at room temperature in traditional superconductors with a Cooper instability in the Fermi sea. Here, Maier et al.report that in the pseudogap phase of cuprate, where ...

A drop in the sea of electrons Understanding the rich physics of Fermi polaron interactions Date: October 20, 2022 Source: ARC Centre of Excellence in Future Low-Energy Electronics Technologies ...

A drop in the Fermi sea. Now, Selim Jochim, Andre Wenz and colleagues at the University of Heidelberg and the Max Planck Institute for Nuclear Physics, both in Germany, have observed this crossover by ...

JILA researchers have tricked nature by tuning a dense quantum gas of atoms to make a congested “Fermi sea,” thus keeping atoms in a high-energy state, or excited, for about 10% longer than ...

That’s because the atoms used in some of these devices can be extremely sensitive to incoming light, and preparing parts of the computers in a Fermi sea could decrease that sensitivity and help ...

The researchers experimentally demonstrated that, when bosons expand in one dimension—the line of atoms is allowed spread out to become longer—they can form a Fermi sea.

Swinburne University of Technology researchers have provided a world’s first measurement of interactions between Fermi polarons in an atomically-thin 2D semiconductor, using ultrafast ...

The Fermi sea describes a collection of weakly interacting identical fermions such as electrons that have been cooled to a very low temperature.
