Ultrafast Magneto-Pressure Spectroscopy and Control of Correlated Phases in a Trilayer Nickelate
Zhi Xiang Chong, Joong-Mok Park, Shuyuan Huyan +10
Ultrafast spectroscopy under simultaneous high pressure and magnetic field provides a versatile approach for investigating pressure-driven electronic instabilities and correlated p…
Extreme Terahertz Nonlinear Phononics by Coherence-Imprinted Control of Hybrid Order
Liang Luo, Avinash Khatri, Martin Mootz +12
Coherent control of quantum materials has progressed along two major fronts: nonlinear phononics, which reshapes lattices to induce emergent states, and Floquet engineering, which…
Vortex-Controlled Quasiparticle Multiplication and Self-Growth Dynamics in Superconducting Resonators
Joong M. Park, Martin Mootz, Richard H. J. Kim +11
Even in the quantum limit, non-equilibrium quasiparticle (QP) populations induce QP poisoning that irreversibly relaxes the quantum state and significantly degrades the coherence o…
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…
Unlocking Quantum Control and Multi-Order Correlations via Terahertz Two-Dimensional Coherent Spectroscopy
Chuankun Huang, Martin Mootz, Liang Luo +2
Terahertz two-dimensional coherent spectroscopy (THz-2DCS) is transforming our ability to probe, visualize, and control quantum materials far from equilibrium. This emerging techni…
Superconductivity and a van Hove singularity confined to the surface of a topological semimetal
Md Shafayat Hossain, Rajibul Islam, Zi-Jia Cheng +16
The interplay between electronic topology and superconductivity is the subject of great current interest in condensed matter physics. For example, superconductivity induced on the…
