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.
These condensates offer insights into frictionless transport, advanced electrical applications, and the fundamental behavior of matter. Their study could impact quantum computing, precision measurement, and the development of lossless electrical conductors.
FIGURE 1: Fermionic condensates, shown in surface plots of time-of-flight absorption images. These condensates of generalized Cooper pairs are created at different interaction strengths in the strongly interacting BCS-BEC crossover regime [1].
7 Αυγ 2020 · In electron systems featuring a fermion condensate, the magnitude of the gap appearing in the single-particle spectrum owing to Cooper pairing is shown to be much larger than that in Bardeen–Cooper–Schrieffer (BCS) theory.
To form the new fermionic condensate, the JILA researchers exploited the Feshbach resonance in two ways in a gas of potassium-40 atoms. First, they tuned the magnetic field to a value corresponding to an effective interparticle attraction, and allowed the gas to equilibrate.
Biomolecular condensates are found throughout eukaryotic cells, in the nucleus, cytoplasm and on various membranes. They are also found across the biological spectrum, organizing molecules that act in processes ranging from RNA metabolism to signaling to gene regulation.
