Sublattice-resolved coherent phonon dynamics in charge density waves
Kyoung Hun Oh, Honglie Ning, Zongqi Shen +15
Phonons govern fundamental material properties and play a central role in various electronic phase transitions. Coherent driving of specific phonon modes enables on-demand phase co…
Dynamics of a jointly commensurate moiré charge density wave
Kyoung Hun Oh, Yifan Su, Honglie Ning +23
The advent of two-dimensional moiré systems has revolutionized the exploration of phenomena arising from strong correlations and nontrivial band topology. Recently, a moiré super…
Coherent terahertz control of metastable magnetization in FePS3
Batyr Ilyas, Tianchuang Luo, Honglie Ning +7
The crystal lattice governs the emergent electronic, magnetic, and optical properties of quantum materials, making structural tuning through strain, pressure, or chemical substitut…
Bidirectional ultrafast control of charge density waves via phase competition
Honglie Ning, Kyoung Hun Oh, Yifan Su +17
The intricate competition between coexisting charge density waves (CDWs) can lead to rich phenomena, offering unique opportunities for phase manipulation through electromagnetic st…
Observation of excitons bound by antiferromagnetic correlations
Omar Mehio, Yuchen Han, Xinwei Li +4
Two-dimensional Mott insulators host antiferromagnetic (AFM) correlations that are predicted to enhance the attractive interaction between empty (holons) and doubly occupied (doubl…
2D van der Waals magnets: from fundamental physics to applications
Je-Geun Park, Kaixuan Zhang, Hyeonsik Cheong +5
Magnetism has played a central role in the long and rich history of modern condensed matter physics, with many foundational insights originating from theoretical studies of two-dim…
