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…
Strong long-wavelength electron-phonon coupling in TaNi(Se,S)
Zhibo Kang, Burak Gurlek, Weichen Tang +9
The search for intrinsic excitonic insulators (EI) has long been confounded by coexisting electron-phonon coupling in bulk materials. Although the ground state of an EI may be diff…
Large moiré superstructure of stacked incommensurate charge density waves
B. Q. Lv, Yifan Su, Alfred Zong +10
Recent advances in van der Waals heterostructures have opened the new frontier of moiré physics, whereby tuning the interlayer twist angle or adjusting lattice parameter mismatch h…
Anomalous excitonic phase diagram in band-gap-tuned Ta2Ni(Se,S)5
Cheng Chen, Weichen Tang, Xiang Chen +17
During a band-gap-tuned semimetal-to-semiconductor transition, Coulomb attraction between electrons and holes can cause spontaneously formed excitons near the zero-band-gap point,…
