Scientists have made a satisfying and intriguing physics discovery some 16 years after it was first predicted to be a possibility: a quasiparticle (a group of particles behaving as one) that only has ...

Researchers have synthesized the first 2D heavy fermion. The material, a layered intermetallic crystal composed of cerium, silicon, and iodine (CeSiI), has electrons that are 1000x heavier and is a ...

Scientists in Japan have uncovered a strange new behavior in “heavy” electrons — particles that act as if they carry far more mass than usual. These electrons were found to be entangled, sharing a ...

What is a Fermi Liquid? A Fermi liquid is a theoretical model that describes the behavior of interacting electrons in metals and other condensed matter systems at low temperatures. It is based on the ...

Enrico Fermi, a Nobel Prizewinner, is one of the principal founders of modern physics. On Dec. 2, 1942, he set in operation the first nuclear reactor, thus became the Prometheus of the Atomic Age.

Electrons that interact with magnetic spins in heavy fermion materials have a heavier-than-usual effective mass. In addition to being a heavy fermion, CeSiI is a van der Waals crystal that can be ...
