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…
