Berry curvature physics and quantum geometric effects have been instrumental in
advancing topological condensed matter physics in recent decades. Although Landau level …

Symmetry breaking in 2D layered materials plays a significant role in their macroscopic
electrical, optical, magnetic and topological properties, including, but not limited to, spin …

Ferroic orders describe spontaneous polarization of spin, charge and lattice degrees of
freedom in materials. Materials exhibiting multiple ferroic orders, known as multiferroics …

The constituent particles of matter can arrange themselves in various ways, giving rise to
emergent phenomena that can be surprisingly rich and often cannot be understood by …

Semiconductor technology is currently based on the manipulation of electronic charge;
however, electrons have additional degrees of freedom, such as spin and valley, that can be …

The emergence of two-dimensional Dirac materials, particularly transition metal
dichalcogenides (TMDs), has reinvigorated interest in valleytronics, which utilizes the …

In a recent work, new two-dimensional materials, monolayer MoSi 2 N 4 and WSi 2 N 4,
were successfully synthesized in experiment, and several other monolayer materials with a …

At the interface of van der Waals heterostructures, the crystal symmetry and the electronic
structure can be reconstructed, giving rise to physical properties superior to or absent in …

We experimentally demonstrate topological edge states arising from the valley-Hall effect in
two-dimensional honeycomb photonic lattices with broken inversion symmetry. We break the …

As an approximation to the quantum state of solids, the band theory, developed nearly
seven decades ago, fostered the advance of modern integrated solid‐state electronics, one …
