7 Αυγ 2020 · We now discuss special features of the fermion-condensate ground state of superdense quark–gluon plasma. Figure 4 shows the results of calculations for the quasiparticle momentum distribution \ (n (p)\) and for the single-particle spectrum \ (\epsilon (p)\) at very low but finite temperatures.
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.
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.
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...
19 Αυγ 2020 · Fermionic Condensate A fermionic condensate is a state of matter similar to a Bose-Einstein condensate, except it consists of fermions, such as quarks and leptons. Normally, the Pauli exclusion principle forbids fermions from entering the same quantum state.
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 (p) = 0 in the momentum-space region adjacent to the Fermi surface and, accordingly...
Examples. Chiral condensate. A chiral condensate is an example of a fermionic condensate that appears in theories of massless fermions with chiral symmetry breaking, such as the theory of quarks in Quantum Chromodynamics. BCS theory. The BCS theory of superconductivity has a fermion condensate.
