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…
Role of Phase Fluctuation in Dynamic Competition Between Charge Order and Superconductivity in Cuprates
Mingu Kang, Pavel E. Dolgirev, Chao C. Zhang +9
Phase fluctuations are a key factor distinguishing nonthermal (ultrafast) and thermal phase transitions. Charge order in cuprates is characterized by short-range coherence while co…
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…
