A fermionic condensate (or Fermi–Dirac condensate) is a superfluid phase formed by fermionic particles at low temperatures. It is closely related to the Bose–Einstein condensate, a superfluid phase formed by bosonic atoms under similar conditions.
27 Μαΐ 2024 · Fermionic condensates represent a captivating phase of matter where particles known as fermions pair up and behave collectively in a quantum state. This phenomenon, observed at extremely low temperatures, challenges our conventional understanding of matter and opens new avenues in quantum physics.
7 Αυγ 2020 · Fermion condensation is a phase transition occurring in a strongly correlated Fermi system upon a topological reconstruction of the Landau ground state and leading to the formation of a fermion condensate that possesses the dispersionless single-particle spectrum \ (\epsilon ( {\mathbf {p}})=0\) in the momentum-space region adjacent to the Fermi...
Experimental work on gases of fermionic atoms in particular has seen large recent progress including the attainment of so-called Fermi condensates. In this article we will discuss this recent development and the unique control over interparticle interactions that made it possible.

For this reason, we were stunned and delighted to learn that Deborah Jin, Cindy Regal and Markus Greiner at the JILA laboratory in the US have created the first fermionic condensate by cooling a gas of potassium atoms to nanokelvin temperatures (Phys. Rev. Lett. 92 040403). Known as “holy grail two” in the ultracold-matter community ...
21 Σεπ 2020 · The ground state of a fermionic condensate is well protected against perturbations in the presence of an isotropic gap. Regions of gap suppression, surfaces and vortex cores which host...
