Spincharge ordering induced by magnetic field in superconducting state: Analytical selfconsistent solution in the twodimensional model
Abstract
A firstorder phase transition is predicted between a spatially homogeneous superconducting state and a state with a spacemodulated composite spinchargesuperconducting order parameter in an applied external magnetic field. In this state the superconducting order changes sign when entering the “stripephase” ordered domain. Corresponding selfconsistent solutions of the Bogoliubovde Gennes equations are found in an analytic form for the twodimensional Hubbard t\textU\textV model with d_{x^2y^2} symmetry of the superconducting order parameter in an external magnetic field.
