Learning Spin Hamiltonians from Terahertz Two-Dimensional Coherent Spectroscopy
Martin Mootz, Chuankun Huang, Liang Luo +2
Effective Hamiltonians connect microscopic interactions to measurable collective behavior in quantum materials, but determining their parameters directly from experiment remains a…
Magnetic Brightening and Nanoscale Imaging of Spin-Polarized Helical Edge Modes
Samuel Haeuser, Richard H. J. Kim, Lin-Lin Wang +9
Efficient sub-10 nm electric transport remains a major challenge for nanoelectronics due to high losses and impedance mismatches in conventional Drude metals. Despite their promise…
Ultrafast Magneto-Pressure Spectroscopy and Control of Correlated Phases in a Trilayer Nickelate

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…
Unveiling Symmetry Instability induced by Topological Phase Transitions
Liang Luo, Boqun Song, Genda Gu +5
The symmetry-topology interplay dictates how to define order parameters and classify material ordered phases. However, current understanding of this interplay has been predominatel…
Observation of the Magnonic Dicke Superradiant Phase Transition
Dasom Kim, Sohail Dasgupta, Xiaoxuan Ma +16
Two-level atoms coupled with single-mode cavity photons are predicted to exhibit a quantum phase transition when the coupling strength exceeds a critical value, entering a phase in…
Discovery of an Unconventional Quantum Echo by Interference of Higgs Coherence
C. Huang, M. Mootz, L. Luo +9
Nonlinearities in quantum systems are fundamentally characterized by the interplay of phase coherences, their interference, and state transition amplitudes. Yet the question of how…
