Diffusion and wave propagation are both fundamental transport mechanisms, but they have
intrinsically different dynamics, governing equations, and applications. Over the past …

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 …

We predict novel topological phases with broken time-reversal symmetry supporting the
coexistence of opposite chiral edge states, which are fundamentally different from the …

Higher-order topological band theory has transformed the landscape of topological phases
in quantum and classical systems. Here, we experimentally demonstrate a two-dimensional …

Thermal transport is a fundamental mechanism of energy transfer process quite distinct from
wave propagation phenomena. It can be manipulated well beyond the possibilities offered …

Compared with conventional topological insulator that carries topological state at its
boundaries, the higher-order topological insulator exhibits lower-dimensional gapless …

The structural periodicity in photonic crystals guarantees the crystal's effective energy band
structure, which is the fundamental cornerstone of topological and moiré physics. However …

Recent studies have identified plasma as a topological material. Yet, these researches often
depict plasma as a fluid governed by electromagnetic fields, ie, a classical wave system …

Higher-order topological phases in non-Hermitian photonics revolutionize the
understanding of wave propagation and modulation, which lead to hierarchical states in …

The non-Hermitian skin effect has been applied in multiple fields. However, there are
relatively few models in the field of thermal diffusion that utilize the non-Hermitian skin effect …
