Stacking-order-dependent electronic properties of MoTe2/WSe2 moiré bilayers
Zhongdong Han, Wenjin Zhao, Eegene Clara Chung +17
Transition metal dichalcogenide (TMD) moiré bilayers have realized a wide range of strongly correlated and topological phenomena. The physics in these materials is often sensitive…
Electric-field-tuned consecutive topological phase transitions between distinct correlated insulators in moire MoTe2/WSe2 heterobilayer
Xumin Chang, Zui Tao, Bowen Shen +10
Consecutive topological phase transitions (TPTs) between strongly correlated electronic phases that differ simultaneously in symmetry breaking and topological order are of fundamen…
Real-Space Quantification of Exciton Localization in Acene Crystals Using Wannier Function Decomposition
Zui Tao, Jonah B. Haber, Jeffrey B. Neaton
We introduce the Wannier function decomposition of excitons (WFDX) method to quantify exciton localization in solids within the ab initio Bethe-Salpeter equation framework. By deco…
Emergence of Chern metal in a moiré Kondo lattice
Wenjin Zhao, Zui Tao, Yichi Zhang +9
A Chern metal is a two-dimensional metallic state of matter carrying chiral edge states. It can emerge as a doped Chern insulator, but theoretical studies have also predicted its e…
Emergence of ferromagnetism at the onset of moiré Kondo breakdown
Wenjin Zhao, Bowen Shen, Zui Tao +9
The interaction of a lattice of localized magnetic moments with a sea of conduction electrons in Kondo lattice models induces rich quantum phases of matter, such as Fermi liquids w…
Observation of spin polarons in a frustrated moiré Hubbard system
Zui Tao, Wenjin Zhao, Bowen Shen +5
The electron's kinetic energy plays a pivotal role in magnetism. While virtual electron hopping promotes antiferromagnetism in an insulator, the real process usually favors ferroma…

We experimentally study the dynamical modes excited by current-induced spin-orbit torque and its electrostatic gating effect in a 3-terminal planar nano-gap spin Hall nano-oscillat…
Giant spin Hall effect in AB-stacked MoTe2/WSe2 bilayers
Zui Tao, Bowen Shen, Wenjin Zhao +9
The spin Hall effect (SHE), in which electrical current generates transverse spin current, plays an important role in spintronics for the generation and manipulation of spin-polari…
