Colossal transverse magnetoresistance due to nematic superconducting phase fluctuations in a copper oxide
Jonatan Wårdh, Mats Granath, Jie Wu +3
Electronic anisotropy (or `nematicity') has been detected in all main families of cuprate superconductors by a range of experimental techniques -- electronic Raman scattering, THz…
Nematic single-component superconductivity and loop-current order from pair-density wave instability
Jonatan Wårdh, Mats Granath
We investigate the nematic and loop-current type orders that may arise as vestigial precursor phases in a model with an underlying pair-density wave (PDW) instability. We discuss h…
Suppression of superfluid stiffness near Lifshitz-point instability to finite momentum superconductivity
Jonatan Wårdh, Mats Granath, Brian M. Andersen
We derive the effective Ginzburg-Landau theory for finite momentum (FFLO/PDW) superconductivity without spin population imbalance from a model with local attraction and repulsive p…
Lattice expansion from isotope substitution in the Iron based superconductors
Oleg Kim, Mats Granath
We estimate the changes in lattice parameters due to iron isotope substitution in the iron-based high temperature superconductors using a variational calculation based on the anhar…
Modeling a striped pseudogap state
M. Granath, B. M. Andersen
We study the electronic structure within a system of phase-decoupled one-dimensional superconductors coexisting with stripe spin and charge density wave order. This system has a no…
Anharmonic softening of Raman active phonons in Iron-Pnictides; estimating the Fe isotope effect due to anharmonic expansion
M. Granath, J. Bielecki, J. Holmlund +1
We present Raman measurements on the iron-pnictide superconductors CeFeAsO_{1-x}F_{x} and NdFeAsO{1-x}F_{x}. Modeling the Fe-As plane in terms of harmonic and a cubic anharmonic Fe…
