Leggett modes and the Anderson-Higgs mechanism in superconductors without inversion symmetry

Nikolaj Bittner, Dietrich Einzel, Ludwig Klam +1

We develop a microscopic and gauge-invariant theory for collective modes resulting from the phase of the superconducting order parameter in non-centrosymmetric superconductors. Con…

Josephson Effect and Triplet--Singlet Ratio of Non--centrosymmetric Superconductors

Ludwig Klam, Anthony Epp, Wei Chen +2

We calculate the Andreev bound states and the corresponding Josephson current for an asymmetric 2-dimensional Josephson junction by solving Bogoliubov-de-Gennes equations. The junc…

Kinetic theory for response and transport in non-centrosymmetric superconductors

Ludwig Klam, Dirk Manske, Dietrich Einzel

We formulate a kinetic theory for non-centrosymmetric superconductors at low temperatures in the clean limit. The transport equations are solved quite generally in spin- and partic…

Electronic and phononic Raman scattering in detwinned YBa $_{2}$ Cu $_{3}$ O $_{6.95}$ and Y $_{0.85}$ Ca $_{0.15}$ Ba $_{2}$ Cu $_{3}$ O $_{6.95}$ : s-wave admixture to the $d_{x^{2} - y^{2}}$ -wave order parameter

M. Bakr, A. P. Schnyder, L. Klam +5

Inelastic light (Raman) scattering has been used to study electronic excitations and phonon anomalies in detwinned, slightly overdoped YBa $_{2}$ Cu $_{3}$ O $_{6.95}$ and moderately overdo…

Electronic Raman scattering in non-centrosymmetric superconductors

Ludwig Klam, Dietrich Einzel, Dirk Manske

We formulate a theory for the polarization-dependence of the electronic (pair-breaking) Raman response for the recently discovered non-centrosymmetric superconductors in the clean…

Response, relaxation and transport in unconventional superconductors

Dietrich Einzel, Ludwig Klam

We investigate the collision-limited electronic Raman response and the attenuation of ultrasound in spin-singlet d-wave superconductors at low temperatures. The dominating elastic…
