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 exc…
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.…
Quantum Nonlinear Acoustic Hall Effect and Inverse Acoustic Faraday Effect in Dirac Insulators
Ying Su, Alexander V. Balatsky, Shi-Zeng Lin
We propose to realize the quantum nonlinear Hall effect and the inverse Faraday effect through the acoustic wave in a time-reversal invariant but inversion broken Dirac insulator.…
Gauge theory of giant phonon magnetic moment in doped Dirac semimetals
Wenqin Chen, Xiao-Wei Zhang, Ying Su +3
We present a quantum theory of phonon magnetic moment in doped Dirac semimetals. Our theory is based on an emergent gauge field approach to the electron-phonon coupling, applicable…
