Quantum Coherence Tomography of Lightwave Controlled Superconductivity
L. Luo, M. Mootz, J. H. Kang +9
Lightwave periodic driving of nearly dissipation-less currents has recently emerged as a universal control concept for both superconducting (SC) and topological electronics applica…
Nonlinear Meissner effect in Nb3Sn coplanar resonators
J. Makita, C. Sundahl, G. Ciovati +2
We investigated the nonlinear Meissner effect (NLME) in NbSn thin film coplanar resonators by measuring the resonance frequency as a function of a parallel magnetic field at di…
Local atomic configuration control of superconductivity in the undoped pnictide parent compound BaFe2As2
Jong-Hoon Kang, Philip J. Ryan, Jong-Woo Kim +13
Emergent superconductivity is strongly correlated with the symmetry of local atomic configuration in the parent compounds of iron-based superconductors. While chemical doping or hy…
Light Quantum Control of Persisting Higgs Modes in Iron-Based Superconductors
C. Vaswani, J. H. Kang, M. Mootz +12
The Higgs mechanism, i.e., spontaneous symmetry breaking of the quantum vacuum, is a cross-disciplinary principle, universal for understanding dark energy, antimatter and quantum m…
Relaxation timescales and electron-phonon coupling in optically-pumped YBaCuO revealed by time-resolved Raman scattering
N. Pellatz, S. Roy, J-W. Lee +6
Time resolved measurements provide a new way to disentangle complex interactions in quantum materials due to their different timescales. We used pump-probe Raman scattering to inve…
Superconductivity in Undoped BaFe2As2 by Tetrahedral Geometry Design
J. H. Kang, J. -W. Kim, P. J. Ryan +9
Fe-based superconductors exhibit a diverse interplay between charge, orbital, and magnetic ordering1-4. Variations in atomic geometry affect electron hopping between Fe atoms5,6 an…
