Magnon cooper pair
WebJun 14, 2004 · Regarding tunneling of Cooper pairs between CuO2 planes. Cooper pairs have a finite spatial extent, called the coherence length L, i.e. their spatial size. In high Tc materials, L is anisotropic, i.e. L is larger in the CuO2 planes (the ab-axis) than perpendicular to the planes (the c-axis), Lab >> Lc. Typically at 0K, Lab = 3nm, and Lc = … WebDec 4, 2024 · The quasiparticle and Cooper pair polarization renormalizes the magnon dispersion. The renormalization results in the splitting of the otherwise degenerate AF magnon modes with no need of applying a magnetic field.

Cooper showed that an arbitrarily small attraction between electrons in a metal can cause a paired state of electrons to have a lower energy than the Fermi energy, which implies that the pair is bound. In conventional superconductors, this attraction is due to the electron–phonon interaction. The Cooper pair state is responsible for superconductivity, as described in the BCS theory developed by John Bardeen, Leon Cooper, and John Schrieffer for which they shared the 1972 No… WebNov 10, 2024 · The effect is dominated by Cooper pairs polarized in the same direction as the ferromagnetic insulator, so that charge and spin supercurrents produce similar …
WebSep 21, 2024 · We introduce a bosonic analog of the Cooper ladder for the magnon pair, which is shown to enhance the pairing of magnons at the Dirac points. As a result of pairing of the Dirac magnons, the system becomes unstable towards formation of a magnetic state with zero magnetization—the Dirac magnon paired state. WebUsing the localized-itinerant model, we find that in ferromagnetic superconducting materials both triplet pairing and singlet pairing of electrons are possible through magnon …
