Tunneling conductance of SIN junctions with different gap symmetries and non-magnetic impurities by direct solution of real-axis Eliashberg equations
G. A. Ummarino, R. S. Gonnelli, D. Daghero
We theoretically investigate the effect of various symmetries of the superconducting order parameter Delta(omega) on the normalized tunneling conductance of SIN junctions by direct…
Possible alterations of the gravitational field in a superconductor
G. A. Ummarino
In this paper I calculate the possible alteration of the gravitational field in a superconductor by using the time-dependent Ginzburg-Landau equations (TDGL). I compare the behavio…
Real-Axis Solution of Eliashberg Equations in Various Order-Parameter Symmetries and Tunneling Conductance of Optimally-Doped HTSC
Giovanni A. Ummarino, Renato S. Gonnelli, Dario Daghero
In the present work we calculate the theoretical tunneling conductance curves of SIN junctions involving high-Tc superconductors, for different possible symmetries of the order par…
Anomalies in the ab-plane resistivity of strongly underdoped La_{2-x}Sr_{x}CuO_{4} single crystals: possible charge stripe ordering?
R. S. Gonnelli, V. A. Stepanov, A. Morello +5
We present and discuss the results of measurements of the ab-plane resistivity of La_{2-x}Sr_{x}CuO_{4} single crystals with small Sr contents (x=0.052-0.075). The resistivity was…
