Designing Flat Bands and Pseudo-Landau Levels in GaAs with Patterned Gates
Pierre A. Pantaleon, Zhen Zhan, Siddhartha E. Morales +1
We investigate the electronic properties of two-dimensional electron gases (2DEGs) subjected to a periodic patterned gate. By incorporating the superlattice (SL) potential induced…
Designing Band Structures by Patterned Dielectric Superlattices
Zhen Zhan, Yonggang Li, Pierre A. Pantaleon
We investigate the electronic structure of graphene monolayers subjected to patterned dielectric superlattices. Through a quantum capacitance model approach, we simulate realistic…
Electronic Structure and Kohn-Luttinger Superconductivity of Heavily-Doped Single-Layer Graphene
Saul Herrera, Guillermo Parra-Martinez, Philipp Rosenzweig +8
The existence of superconductivity (SC) in graphene appears to be established in both twisted and non-twisted multilayers. However, whether their building block, single-layer graph…
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…
