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…
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…
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 superst…
Time-domain decoding of unconventional charge order mechanisms in nonmagnetic and magnetic kagome metals
Seongyong Lee, Byungjune Lee, Hoyoung Jang +11
In kagome lattice materials, quantum interplay between charge, spin, orbital, and lattice degrees of freedom gives rise to a remarkably rich set of emergent phenomena, ranging from…
Ultrafast Orbital-Selective Photodoping Melts Charge Order in Overdoped Bi-based Cuprates
Xinyi Jiang, Qizhi Li, Qingzheng Qiu +10
High-temperature superconductivity in cuprates remains one of the enduring puzzles of condensed matter physics, with charge order (CO) playing a central yet elusive role, particula…
Symmetry-protected electronic metastability in an optically driven cuprate ladder
Hari Padma, Filippo Glerean, Sophia F. R. TenHuisen +23
Optically excited quantum materials exhibit nonequilibrium states with remarkable emergent properties, but these phenomena are usually transient, decaying on picosecond timescales…
Frustrated phonon with charge density wave in vanadium Kagome metal
Seung-Phil Heo, Choongjae Won, Heemin Lee +12
The formation of a star of David CDW superstructure, resulting from the coordinated displacements of vanadium ions on a corner sharing triangular lattice, has garnered significant…
Orbital-selective time-domain signature of nematicity dynamics in the charge-density-wave phase of LaEuSrCuO
Martin Bluschke, Naman K. Gupta, Hoyoung Jang +23
Understanding the interplay between charge, nematic, and structural ordering tendencies in cuprate superconductors is critical to unraveling their complex phase diagram. Using pump…
Ultrafast X-ray imaging of the light-induced phase transition in VO2
Allan S. Johnson, Daniel Pérez-Salinas, Khalid M. Siddiqui +26
Using light to control transient phases in quantum materials is an emerging route to engineer new properties and functionality, with both thermal and non-thermal phases observed ou…
4D visualization of the photoexcited coherent magnon by an X-ray free electron laser
Hoyoung Jang, Hiroki Ueda, Hyeong-Do Kim +12
X-ray free electron lasers (XFEL) create femtosecond X-ray pulses with high brightness and high longitudinal coherence allowing to extend X-ray spectroscopy and scattering techniqu…
