Quantum Melting of a Disordered Wigner Solid
Ziyu Xiang, Hongyuan Li, Jianghan Xiao +15
The behavior of two-dimensional electron gas (2DEG) in extreme coupling limits are reasonably well-understood, but our understanding of intermediate region remains limited. Strongl…
Wigner Molecular Crystals from Multi-electron Moiré Artificial Atoms
Hongyuan Li, Ziyu Xiang, Aidan P. Reddy +10
Semiconductor moiré superlattices provide a versatile platform to engineer new quantum solids composed of artificial atoms on moiré sites. Previous studies have mostly focused on t…
Imaging Moiré Excited States with Photocurrent Tunneling Microscopy
Hongyuan Li, Ziyu Xiang, Mit H. Naik +12
Moiré superlattices provide a highly tunable and versatile platform to explore novel quantum phases and exotic excited states ranging from correlated insulators1-17 to moiré excito…
Interplay of trapped species and absence of electron capture in Moiré heterobilayers
Arnab Barman Ray, Arunabh Mukherjee, Liangyu Qiu +3
Moiré heterobilayers host interlayer excitons in a natural, periodic array of trapping potentials. Recent work has elucidated the structure of the trapped interlayer excitons and t…
Mapping Charge Excitations in Generalized Wigner Crystals
Hongyuan Li, Ziyu Xiang, Emma Regan +9
Transition metal dichalcogenide-based moire superlattices exhibit very strong electron-electron correlations, thus giving rise to strongly correlated quantum phenomena such as gene…
Revealing the order parameter dynamics of 1T-TiSe following optical excitation
Maximilian Huber, Yi Lin, Nicholas Dale +4
The formation of a charge density wave state is characterized by an order parameter. The way it is established provides unique information on both the role that correlation plays i…
Charge transfer dynamics in MoSe/hBN/WSe heterostructures
Yoseob Yoon, Zuocheng Zhang, Ruishi Qi +6
Ultrafast charge transfer processes provide a facile way to create interlayer excitons in directly contacted transition metal dichalcogenide (TMD) layers. More sophisticated hetero…
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…
Mapping the dispersion of the occupied and unoccupied band structure in photoexcited 1T-TiSe
Maximilian Huber, Yi Lin, Nicholas Dale +4
Charge density waves (CDW) are states of broken symmetry with a periodic modulation of charge and lattice typically leading to the opening of a gap in the band structure. In the mo…
Intrinsic circularly-polarized exciton emission in a twisted van-der-Waals heterostructure
J. Michl, S. A. Tarasenko, F. Lohof +12
The investigation of excitons in van-der-Waals heterostructures has led to profound insights into the interplay of crystal symmetries and fundamental effects of light-matter coupli…
