15 Nov 2004 | | Subject: | Superconductivity | cond-mat.supr-con | | Abstract: | A model for the coexistence of p-wave superconductivity (SC) and ferroelectricity (FE) is presented. The Hamiltonian of SC sector and FE sector can be diagonalized by using the $so(5)$ and $h(4)$ algebraic coherent states respectively. We assume a minimal symmetry-allow coupling and simplify the total Hamiltonian through a double mean-field approximation (DMFA). A variational coherent-state (VCS) trial wave-function is applied for the ground state. It is found that the ferroelectricity gives rise to the magnetic field effect of p-wave superconductivity. | | Source: | arXiv, cond-mat/0411369 | | Services: | Forum | Review | PDF | Favorites | |
