Propagating Collective Spin-valley Modes in Twisted WSe2
Richen Xiong, Yi Guo, Chenxin Qin +15
The emergence of neutral collective modes is a hallmark of correlated quantum phases but is often challenging to probe experimentally. In two-dimensional flatband systems, charge r…
Tunable exciton valley-pseudospin orders in moiré Bose-Hubbard model
Richen Xiong, Samuel L. Brantly, Kaixiang Su +9
Spin and charge are the two most important degrees of freedom of electrons. Their interplay lies at the heart of numerous strongly correlated phenomena including Hubbard model phys…
Correlated insulator of excitons in WSe2/WS2 moiré superlattices
Richen Xiong, Jacob H. Nie, Samuel L. Brantly +6
A panoply of unconventional electronic states has been observed in moiré superlattices. Engineering similar bosonic phases remains, however, largely unexplored. We report the obser…
