Spectroscopic signatures of different symmetries of the superconducting order parameter in metal-decorated graphene
Timo Saari, Jouko Nieminen, Arun Bansil
Motivated by the recent experiments indicating superconductivity in metal-decorated graphene sheets, we investigate their quasi-particle structure within the framework of an effect…
The high-energy anomaly in ARPES spectra of the cuprates-many body or matrix element effect?
E. D. L. Rienks, M. Ärrälä, M. Lindroos +5
We used polarization-dependent angle-resolved photoemission spectroscopy (ARPES) to study the high-energy anomaly (HEA) in the dispersion of Nd2-xCexCuO4, (x=0.123). We have found…
Ripple field losses in DC biased superconductors: simulations and comparison with measurements
V. Lahtinen, E. Pardo, J. Šouc +2
For example in some supercondcuting generators, motors and power transmission cables the superconductor experiences a changing magnetic field in a DC background. Simulating the los…
Influence of the voltage taps position on the self-field DC and AC transport characterization of HTS superconducting tapes
M. Vojenciak, F. Grilli, A. Stenvall +2
The current-voltage (I-V) curve is the basic characteristic of a superconducting wire or tape. Measuring I-V curves is generally problematic when samples have poor stabilization. S…
Computation of Losses in HTS Under the Action of Varying Magnetic Fields and Currents
Francesco Grilli, Enric Pardo, Antti Stenvall +3
Numerical modeling of superconductors is widely recognized as a powerful tool for interpreting experimental results, understanding physical mechanisms and predicting the performanc…
Spectral decomposition and matrix element effects in scanning tunneling spectroscopy of BiSrCaCuO
Jouko Nieminen, Ilpo Suominen, R. S. Markiewicz +2
We present a Green's function based framework for modeling the scanning tunneling spectrum from the normal as well as the superconducting state of complex materials where the natur…
Effect of orbital symmetry of the tip on Scanning Tunneling Spectra of BiSrCaCuO
Ilpo Suominen, Jouko Nieminen, R. S. Markiewicz +1
We discuss how variations in the scanning tunneling microscope (STM) tip, whether unintentional or intentional, can lead to changes in topographic images and dI/dV spectra. We cons…
Induced superconductivity in noncuprate layers of the BiSrCaCuO high-temperature superconductor: Modeling of scanning tunneling spectra
Ilpo Suominen, Jouko Nieminen, R. S. Markiewicz +1
We analyze how the coherence peaks observed in Scanning Tunneling Spectroscopy (STS) of cuprate high temperature superconductors are transferred from the cuprate layer to the oxide…
Origin of the high-energy kink or the waterfall effect in the photoemission spectrum of the high-temperature superconductor
Susmita Basak, Tanmoy Das, Hsin Lin +4
The high-energy kink or the waterfall effect seen in the photoemission spectra of the cuprates is suggestive of the coupling of the quasiparticles to a high energy bosonic mode wit…
Origin of electron-hole asymmetry in the scanning tunneling spectrum of
Jouko Nieminen, Hsin Lin, R. S. Markiewicz +1
We have developed a material specific theoretical framework for modelling scanning tunneling spectroscopy (STS) of high temperature superconducting materials in the normal as well…
Evolution of Mid-gap States and Residual 3-Dimensionality in LaSrCuO
S. Sahrakorpi, M. Lindroos, R. S. Markiewicz +1
We have carried out extensive first principles doping-dependent computations of angle-resolved photoemission (ARPES) intensities in LaSrCuO (LSCO) over a wide range…
Influence of the Third Dimension of Quasi-Two-Dimensional Cuprate Superconductors on Angle-Resolved Photoemission Spectra
A. Bansil, M. Lindroos, S. Sahrakorpi +1
Angle-resolved photoemission spectroscopy (ARPES) presents significant simplications in analyzing strictly two-dimensional (2D) materials, but even the most anisotropic physical sy…
