Strain Correlated Linearly Polarized Photoluminescence in WS2/WSe2 Moiré Superlattices
Yuto Urano, Ryo Tamura, Yui Tamogami +6
Reliable optical control of valley degrees of freedom in moiré excitons requires that the emitted polarization faithfully reflect the underlying valley state. Here, we show that l…
Layer-Selective Proximity Symmetry Breaking Enables Anomalous and Nonlinear Hall Responses in 1H-TMD Metals
Yusuf Wicaksono, Toshikaze Kariyado
Nonlinear Hall responses are a direct electrical probe of quantum geometry, but they are symmetry-forbidden in many pristine two-dimensional metals. We show that layer-selective ma…
Moiré in -valley square lattice: Copper- and iron-based superconductor simulation in a single device
Toshikaze Kariyado, Yusuf Wicaksono, Ashvin Vishwanath +2
Novel superconducting phases have been found in various moiré heterostructures based on hexagonal lattices. However, the archetypal high-temperature superconductors (cuprates, iro…
Domain Wall Sliding-induced Polarization Switching in Multilayer Graphene
Zhou Zhou, Xiyao Peng, Jianfeng Bi +7
Electric polarization and metallicity are long believed not to coexist until the emergence of exceptionally rare material examples including the bulk polar metals and more recently…
Single-band square lattice Hubbard model from twisted bilayer C568
Toshikaze Kariyado, Ashvin Vishwanath, Zhu-Xi Luo
We propose twisted homobilayer of a carbon allotrope, C, to be a promising platform to realize controllable square lattice single-band extended Hubbard model. This setup ha…
Strongly hybridized phonons in one-dimensional van der Waals crystals
Shaoqi Sun, Qingyun Lin, Yihuan Li +7
The phenomena of pronounced electron-electron and electron-phonon interactions in one-dimensional (1D) systems are ubiquitous, which are well described by frameworks of Luttinger l…
