Measuring Phonon Dispersion and Electron-Phason Coupling in Twisted Bilayer Graphene with a Cryogenic Quantum Twisting Microscope
John Birkbeck, Jiewen Xiao, Alon Inbar +7
The coupling between electrons and phonons is one of the fundamental interactions in solids, underpinning a wide range of phenomena such as resistivity, heat conductivity, and supe…
Theory of phonon spectroscopy with the quantum twisting microscope
Jiewen Xiao, Erez Berg, Leonid I. Glazman +3
We develop a theory of probing phonon modes of van-der-Waals materials using the quantum twisting microscope. While elastic tunneling dominates the tunneling current at small twist…
Optical Absorption and Emission from Wannier-Stark Spectra of Moiré Superlattices
Vo Tien Phong, Francisco Guinea, Cyprian Lewandowski
Using a formalism based on the non-Abelian Berry connection, we explore quantum geometric signatures of Wannier-Stark spectra in two-dimensional superlattices. The Stark energy can…
Strain and twist angle driven electronic structure evolution in twisted bilayer graphene
Jiawei Yu, Guihao Jia, Qian Li +14
In twisted bilayer graphene (TBG) devices, local strains frequently coexist and intertwine with the twist-angle-dependent moiré superlattice, significantly influencing the electron…
Terahertz photocurrent probe of quantum geometry and interactions in magic-angle twisted bilayer graphene
Roshan Krishna Kumar, Geng Li, Riccardo Bertini +24
Moiré materials represent strongly interacting electron systems bridging topological and correlated physics. Despite significant advances, decoding wavefunction properties underlyi…
Flat bands in chiral multilayer graphene
Roi Makov, Francisco Guinea, Ady Stern
We study the formation and properties of perfectly-flat zero energy bands in a multi-layer graphene systems in the chiral limit. Employing the degrees of freedoms of the multi-laye…
Infrared Spectroscopy for Diagnosing Superlattice Minibands in Magic-angle Twisted Bilayer Graphene
Geng Li, Roshan Krishna Kumar, Petr Stepanov +11
Twisted bilayer graphene (TBG) represents a highly tunable, strongly correlated electron system owed to its unique flat electronic bands. However, understanding the single-particle…
Optical properties and plasmons in moiré structures
Xueheng Kuang, Pierre A. Pantaleón Peralta, Jose Angel Silva-Guillén +3
The discoveries of numerous exciting phenomena in twisted bilayer graphene (TBG) are stimulating significant investigations on moiré structures that possess a tunable moiré potenti…
Robust flat bands in twisted trilayer graphene quasicrystals
Chen-Yue Hao, Zhen Zhan, Pierre A. Pantaleón +6
Moiré structures formed by twisting three layers of graphene with two independent twist angles present an ideal platform for studying correlated quantum phenomena, as an infinite s…
