Strong Correlation Driven Quadrupolar to Dipolar Exciton Transitions in a Trilayer Moiré Superlattice
Yuze Meng, Lei Ma, Li Yan +13
The additional layer degree of freedom in trilayer moiré superlattices of transition metal dichalcogenides enables the emergence of novel excitonic species, such as quadrupolar ex…

Geometric Origin of Phonon Magnetic Moment in Dirac Materials
Wenqin Chen, Xiao-Wei Zhang, Ting Cao +2
We develop a theory for the phonon magnetic moment in doped Dirac materials, treating phonons as emergent gauge and gravitational fields coupled to Dirac fermions in curved space.…
