The Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) state of a two-dimensional (2D) orthorhombic lattice superconductor is studied based on the Bogoliubov–de-Gennes equations. It is illustrated that the 2D FFLO state is suppressed and only the one-dimensional (1D) stripe state is stable. Our numerical results also reveal a phase transition with the stripe changing its orientation upon increasing the Zeeman field. A phase coexistence region exists with some local 2D features. The free energy is studied… Expand
