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.
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.
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...
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...
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.
21 Ιουν 2024 · Here we characterize the collective oscillations of spin-polarized fermionic impurities immersed in a Bose–Einstein condensate as a function of the interaction strength and temperature.
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.
