Observation of Andreev bound states in YBaCuO/Au/Nb ramp-type Josephson junctions
B. Chesca, D. Doenitz, T. Dahm +6
We report on Josephson and quasiparticle tunneling in YBa2Cu3O7-x(YBCO)/Au/Nb ramp junctions of several geometries. Macroscopically, tunneling occurs in the ab-plane of YBCO either…
Anomaly at Delta_k in the ARPES spectrum of dirty superconductors
T. Dahm, P. J. Hirschfeld, L. Zhu +1
Elastic forward scattering can lead to an anomaly in the ARPES spectrum of the cuprate superconductors. Here we discuss how this anomaly can be used to provide a measurement of the…
Nonlinear microwave response of MgB2
T. Dahm, D. J. Scalapino
We calculate the intrinsic nonlinear microwave response of the two gap superconductor MgB2 in the clean and dirty limits. Due to the small value of the pi band gap, the nonlinear r…
Correlation of microwave surface impedance of MgB_2 thin film with material parameters and a temperature niche for microwave applications
B. B. Jin, T. Dahm, C. Iniotakis +11
Two issues related to the microwave surface impedance Z_s of MgB_2 thin film are discussed in this Letter, both being significant for potential microwave applications. At first, a…
Anatomy of Gossamer Superconductivity
Stephan Haas, Kazumi Maki, Thomas Dahm +1
There are many systems in which two order parameters compete with each other. Of particular interest are systems in which these order parameters are both unconventional. In this co…
Influence of Fermi surface topology on the quasiparticle spectrum in the vortex state
S. Graser, T. Dahm, N. Schopohl
We study the influence of Fermi surface topology on the quasiparticle density of states in the vortex state of type II superconductors. We observe that the field dependence and the…
