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…
Discovery of transient topological crystalline order in optically driven SnSe
Masataka Mogi, Dongsung Choi, Kyoung Hun Oh +13
Ultrafast optical excitation provides a powerful route for accessing emergent quantum phases far from equilibrium, enabling transient light-induced phenomena such as magnetism, fer…
Time-domain identification of distinct mechanisms for competing charge density waves in a rare-earth tritelluride
Yifan Su, B. Q. Lv, Alfred Zong +12
Understanding the origin of phase transitions and the interactions between distinct phases remains a central task in condensed matter physics. Charge density wave (CDW) systems pro…
Direct observation of a photoinduced topological phase transition in Bi-doped (Pb,Sn)Se
Masataka Mogi, Dongsung Choi, Louis Primeau +6
Ultrafast photoexcitation offers a novel approach to manipulating quantum materials. One of the long-standing goals in this field is to achieve optical control over topological pro…
