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…
Lightwave Terahertz Quantum Manipulation of Non-equilibrium Superconductor Phases and their Collective Modes
Martin Mootz, Jigang Wang, Ilias E. Perakis
We present a gauge-invariant density matrix description of non-equilibrium superconductor (SC) states with spatial and temporal correlations driven by intense terahertz (THz) light…
Discovery of Terahertz Second Harmonic Generation from Lightwave Acceleration of Symmetry--Breaking Nonlinear Supercurrents
C. Vaswani, C. Sundahl, M. Mootz +11
We report terahertz (THz) second harmonic generation (SHG) in superconductors (SC) with inversion symmetric equilibrium states that forbid even-order nonlinearities. Such SHG signa…
Charge Density Wave Modulation in Superconducting BaPbO/BaBiO Superlattices
D. T. Harris, N. Cambell, C. Di +9
The isotropic, non-magnetic doped BaBiO superconductors maintain some similarities to high-Tc cuprates, while also providing a cleaner system for isolating charge density wave…
Non-equilibrium Pair Breaking in Ba(Fe1-xCox)2As2 Superconductors: Evidence for Formation of Photo-Induced Excitonic Spin-Density-Wave State
X. Yang, L. Luo, M. Mootz +5
Ultrafast terahertz (THz) pump{probe spectroscopy reveals unusual out-of-equilibrium Cooper pair dynamics driven by femtosecond (fs) optical quench of superconductivity (SC) in iro…
