Nodal Quasiparticle Lifetimes in Cuprate Superconductors
T. Dahm, P. J. Hirschfeld, D. J. Scalapino +1
A new generation of angular-resolved photoemission spectroscopy (ARPES) measurements on the cuprate superconductors offer the promise of enhanced momentum and energy resolution. In…
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…
Shadow on the wall cast by an Abrikosov vortex
S. Graser, C. Iniotakis, T. Dahm +1
At the surface of a d-wave superconductor, a zero-energy peak in the quasiparticle spectrum can be observed. This peak appears due to Andreev bound states and is maximal if the nod…
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…
