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
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…
CDW Gap Collapse and Weyl State Restoration in (TaSe4)2I via Coherent Phonons: A First-Principles Study
Tao Jiang, Jigang Wang, Yong-Xin Yao
Coherent phonon excitation offers a nonthermal route to control quantum phases of condensed matter. In this work, we employ first-principles calculations to investigate the phonon…
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…
Revealing Fano Resonance in Dirac Materials ZrTe5 through Raman Scattering
Di Cheng, Tao Jiang, Feng Zhang +10
We explore the Fano resonance in ZrTe5, using Raman scattering measurements. We identified two closely spaced B2g phonon modes, B2g I and B2g II, around 9 meV and 10 meV, respectiv…
