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…
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 TaSeI 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…
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…
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…
Coexistence of low and high spin states in LaCoPb
Weiyi Xia, Vladimir Antropov, Yongxin Yao +1
The electronic structure and magnetic properties of a newly predicted stable ternary compound LaCoPb are studied using electronic structure analysis. The ground…
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…
Ultrafast Terahertz Conductivity Probes of Topologically Enhanced Surface Transport Driven by Mid-Infrared Laser Pulses in BiSe
L. Luo, X. Yang, X. Liu +8
The recent discovery of topology-protected charge transport of ultimate thinness on surfaces of three-dimensional topological insulators (TIs) are breaking new ground in fundamenta…
