Observation of Superconducting Solitons by Terahertz-Light-Driven Persistent Pseudo-Spin Coherence
M. Mootz, C. Vaswani, C. Huang +8
Overcoming the decoherence bottleneck remains a central challenge for advancing coherent superconducting quantum device and information technologies. Solitons -- non-dispersive wav…
Coherent Transfer of Lattice Entropy via Extreme Nonlinear Phononics in Metal Halide Perovskites
Z. Liu, Y. Shi, T. Jiang +8
Entropy transfer in metal halide perovskites, characterized by significant lattice anharmonicity and low stiffness, underlies the remarkable properties observed in their optoelectr…
Extreme Terahertz Magnon Multiplication Induced by Resonant Magnetic Pulse Pairs
C. Huang, L. Luo, M. Mootz +7
Nonlinear interactions of spin-waves and their quanta, magnons, have emerged as prominent candidates for interference-based technology, ranging from quantum transduction to antifer…
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…
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…
Light-Driven Raman Coherence as a Non-Thermal Route to Ultrafast Topology Switching
C. Vaswani, L. -L. Wang, D. H. Mudiyanselage +14
A grand challenge underlies the entire field of topology-enabled quantum logic and information science: how to establish topological control principles driven by quantum coherence…
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…
Ultrafast Control of Excitonic Rashba Fine Structure by Phonon Coherences in a Metal Halide Perovskite CHNHPbI
Z. Liu, C. Vaswani, X. Yang +14
We discover hidden Rashba fine structure in CHNHPbI and demonstrate its quantum control by vibrational coherence through symmetry-selective vibronic (electron-phonon) c…
