Revealing a Pauli Crystal

Physics 14, 5
A novel, high-resolution fluorescence imaging technique reveals a pattern, known as a Pauli crystal, that can emerge in a cloud of trapped, noninteracting fermions.
Figure 1: As a consequence of the Pauli exclusion principle, a few fermions trapped by lasers self-organize into a periodic structure called a Pauli crystal. By combining single-particle snapshots of the system, Marvin Holton and colleagues measure the multiparticle correlations that reveal the formation of a Pauli crystal.As a consequence of the Pauli exclusion principle, a few fermions trapped by lasers self-organize into a periodic structure called a Pauli crystal.

Researchers Identify Novel Topological Properties in Cobalt Disulfide

The Schoop Lab, which is heading an association of institutions both in the United States and overseas, has reported unexpected new topological characteristics of cobalt disulfide (CoS

The researchers used ab-initio calculations and angle-resolved photoelectron spectroscopy and observed that bulk CoS
2 contains Weyl nodes. These Weyl nodes enabled the team to make predictions about the surface properties of this material.
Within its band structure, the material contains Weyl-fermions and Fermi-arc surface states, which may allow it to act as a platform for unusual phenomena and also places it among materials candidates for applications in spintronic devices.

Electrons inhabit a strange and topsy-turvy world. These infinitesimally small particles have never ceased to amaze and mystify despite the more than a century that scientists have studied them. Now, in an even more amazing twist, physicists have discovered that, under certain conditions, interacting electrons can create what are called topological quantum states. This finding, which was recently published in the journal
