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 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...
متن کاملEvidence for the Fulde-Ferrell-Larkin-Ovchinnikov state in CeCoIn5 from penetration depth measurements
We report penetration depth and resistivity measurements on the heavy fermion superconductor CeCoIn5 using a self-resonant tank circuit based on a tunnel diode oscillator. For magnetic fields applied near parallel to the ab planes and temperatures below 250 mK, two phase transitions were found. The lower field transition, within the superconducting state, is of a second order and we identify it...
