A development of superconducting differential double contour interferometer
V. L. Gurtovoi, V. N. Antonov, A. V. Nikulov +2
We study operation of a new device, the superconducting differential double contour interferometer (DDCI), in application for the ultra sensitive detection of magnetic flux and for…
The three-dimensional electronic structure of the nematic and antiferromagnetic phases of NaFeAs from detwinned ARPES measurements
Matthew D. Watson, Saicharan Aswartham, Luke C. Rhodes +6
We report a comprehensive ARPES study of NaFeAs, a prototypical parent compound of the Fe-based superconductors. By mechanically detwinning the samples, we show that in the nematic…
Pseudo-spin Skyrmions in the Phase Diagram of Cuprate Superconductors
Corentin Morice, Debmalya Chakraborty, Xavier Montiel +1
Topological states of matter are at the root of some of the most fascinating phenomena in condensed matter physics. Here we argue that skyrmions in the pseudo-spin space related to…
Vacuum-induced Autler-Townes splitting in a superconducting artificial atom
Z. H. Peng, J. H. Ding, Y. Zhou +7
We experimentally study a vacuum-induced Autler-Townes doublet in a superconducting three-level artificial atom strongly coupled to a coplanar waveguide resonator and simultaneousl…
Electronic anisotropies revealed by detwinned ARPES measurements of FeSe
Matthew D Watson, Amir A. Haghighirad, Luke C. Rhodes +2
We report high resolution ARPES measurements of detwinned FeSe single crystals. The application of a mechanical strain is used to promote the volume fraction of one of the orthorho…
Evolution of spectral and transport quantities with doping in the SU(2) theory of cuprates
Corentin Morice, Xavier Montiel, Catherine Pépin
Recent transport experiments in the cuprate superconductors linked the opening of the pseudogap to a change in electronic dispersion [S. Badoux et al., Nature 531, 210 (2015)]. Tra…
A model for the neutron resonance in HgBaCuO
X. Montiel, C. Pépin
We study the spin dynamics of the Resonant Excitonic State (RES) proposed, within the theory of an emergent SU(2) symmetry, to explain some properties of the pseudo-gap phase of cu…
Strongly enhanced temperature dependence of the chemical potential in FeSe
L. C. Rhodes, M. D. Watson, A. A. Haghighirad +2
Employing a 10-orbital tight binding model, we present a new set of hopping parameters fitted directly to our latest high resolution angle-resolved photoemission spectroscopy (ARPE…
Superconducting spin valves controlled by spiral re-orientation in B20-family magnets
N. G. Pugach, M. Safonchik, T. Champel +4
We propose a superconducting spin-triplet valve, which consists of a superconductor and an itinerant magnetic material, with the magnet showing an intrinsic non-collinear order cha…
Spectroscopic evidence of odd frequency superconducting order
Avradeep Pal, Jabir Ali Ouassou, Matthias Eschrig +2
Spin filter superconducting S/I/N tunnel junctions (NbN/GdN/TiN) show a robust and pronounced zero bias conductance peak at low temperatures, the magnitude of which is several time…
Theory of surface spectroscopy for noncentrosymmetric superconductors
N. Wennerdal, M. Eschrig
We study noncentrosymmetric superconductors with the tetrahedral , tetragonal , and cubic point group . The order parameter is computed self-consistently in the bul…
