WebDec 21, 2024 · The sSC and dSC here can be naturally related to the charge-density wave (CDW) and SDW fluctuations, both of which can be triggered by the SSH phonons. In contrast, the repulsive interaction U enhances SDW but suppresses CDW fluctuations. Our results at half filling are consistent with quantum Monte Carlo (QMC) and provide insights … WebSep 28, 2024 · In the late 1980s, soon after the discovery of HTSC cuprates, Schreiffer, Wen and Zhang proposed a so-called spin-bag mechanism for the origin of SC pairing in these systems [1, 2].According to the fact that the spin density wave (SDW) order persists for a finite range of doping close to the SC dome, and the SDW wavevector \(\mathbf …
WebSDW instabihty the interaction V, (p',p), Eq. (1),is posi-tive definite. However, its Fourier transform can oscillate and the electrons making up a pair can arrange their space-time correlations to fit into the attractive regions.
