Topological acoustics is an emerging field that lies at the intersection of condensed matter
physics, mechanical structural design and acoustics engineering. It explores the design and …

Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

The integer quantum anomalous Hall (QAH) effect is a lattice analogue of the quantum Hall
effect at zero magnetic field,–. This phenomenon occurs in systems with topologically non …

The discovery and control of new phases of matter is a central endeavour in materials
research. The emergence of atomically thin 2D materials, such as transition-metal …

Diffusion driven by temperature or concentration gradients is a fundamental mechanism of
energy and mass transport that inherently differs from wave propagation in both physical …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

Light and sound are the most ubiquitous forms of waves, associated with a variety of
phenomena and physical effects such as rainbows and echoes. Light and sound, both …

We demonstrate via exact diagonalization that AA-stacked transition metal dichalcogenide
homobilayers host fractional quantum anomalous Hall (FQAH) states with fractionally …

Quantum spin Hall (QSH) insulators are two-dimensional electronic materials that have a
bulk band gap similar to an ordinary insulator but have topologically protected pairs of edge …

Spintronics is one of the emerging fields for the next-generation nanoelectronic devices to
reduce their power consumption and to increase their memory and processing capabilities …
