Electron-energy-loss spectra and the structural stability of nickel oxide: An LSDA+U study

We demonstrate how by taking better account of electron correlations in the $3d$ shell of metal ions in nickel oxide it is possible to improve the description of both electron energy loss spectra and

Magic in twisted transition metal dichalcogenide bilayers

The rich physics at small twist angles is revealed, and a particular magic angle is identified at which the top valence moiré band achieves almost perfect flatness and the combination of flat dispersion and uniformity of Berry curvature near the magic angle holds promise for realizing fractional quantum anomalous Hall effect at fractional filling.

Moiré Skyrmions and Chiral Magnetic Phases in Twisted CrX3 (X = I, Br, and Cl) Bilayers.

It is demonstrated that for small twist angles various skyrmion crystal phases can be stabilized in both CrI3 and CrBr3 and the possibility of engineering further nontrivial magnetic ground states in twisted bilayer chromium trihalides is demonstrated.

Electron Scattering on a Magnetic Skyrmion in the Nonadiabatic Approximation.

The theory explains the appearance of a topological Hall current in the systems with magnetic Skyrmions, the special importance of which is its applicability to dilute magnetic semiconductors with a weak exchange interaction.

Van der Waals engineering of ferromagnetic semiconductor heterostructures for spin and valleytronics

The photoluminescence detection of valley pseudospin provides a simple and sensitive method to probe the intriguing domain dynamics in the ultrathin magnet, as well as the rich spin interactions within the heterostructure.

Spin-textured Chern bands in AB-stacked transition metal dichalcogenide bilayers

The displacement field–induced topological moiré bands in AB-stacked transition-metal dichalcogenide (TMD) heterobilayer MoTe2/WSe2 are revealed and established, which provides a highly tunable platform for realizing quantum-spin Hall and interaction-induced quantum anomalous Hall effects.

Twisted magnetic topological insulators

Motivated by the discovery of quantum anomalous Hall effect in Cr-doped Bi2Se3, we study the generic states for magnetic topological insulators and explore the physical properties for both magnetism

Topological magnetic textures in magnetic topological insulators

The surfaces of intrinsic magnetic topological insulators (TIs) host magnetic moments exchange-coupled to Dirac electrons. We study the magnetic phases arising from tuning the electron density using

Skyrmions in the Moiré of van der Waals 2D Magnets.

A new origin of skyrmions in the 2D magnets from the lateral modulation of interlayer magnetic coupling by the locally different atomic registries in moiré is demonstrated.
