Fulde-Ferrell-Larkin-Ovchinnikov state in d-wave superconductors
The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state can be found in layered dwave superconductors such as high Tc cuprates and κ-(ET)2 salts in a planar magnetic field. We show the superconducting order parameter forms two dimensional crystalline lattice in the FFLO state for d-wave superconductors. Also the quasiparticle density of states and the thermodynamics of FFLO state are constructed. The...
متن کاملVortex tilt modulus in Fulde-Ferrell-Larkin-Ovchinnikov state
Vortex tilt response in a Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) vortex lattice is studied as a probe reflecting the spatial structure of this state. In quasi 2D materials under a parallel magnetic field, the tilt modulus E2 of the nodal planes in the FFLO state modulating along the field decreases as the paramagnetic effect is effectively enhanced, and this reduction of E2 in turn reduces the...
متن کاملDisordered Fulde-Ferrel-Larkin-Ovchinnikov state in d-wave superconductors
We study the Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) superconducting state in the disordered systems. We analyze the microscopic model, in which the dwave superconductivity is stabilized near the antiferromagnetic quantum critical point, and investigate two kinds of disorder, namely, box disorder and point disorder, on the basis of the Bogoliubov-deGennes (BdG) equation. The spatial structure of...
متن کاملTheory of tunneling spectroscopy in the Larkin-Ovchinnikov state.
We present a theory of tunneling spectroscopy for normal metal/Larkin-Ovchinnikov state junctions in which the spatial periodic modulation in the pair potential amplitude is taken into account. The tunneling spectra show the characteristic line shapes reflecting the minigap structures under the periodic pair potentials depending on the boundary condition of the pair potentials at the junction i...
متن کاملLarkin-Ovchinnikov-Fulde-Ferrell state in quasi-one-dimensional superconductors.
The properties of a quasi-one-dimensional (quasi-1D) superconductor with an open Fermi surface are expected to be unusual in a magnetic field. On the one hand, the quasi-1D structure of the Fermi surface strongly favors the formation of a non-uniform state (Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) state) in the presence of a magnetic field acting on the electron spins. On the other hand, a magne...
