Standard model as the topological material
New Journal of Physics, 2017 The study of the Weyl and Dirac topological materials (topological semimetals, insulators, superfluids and superconductors) opens the route for the investigation of the topological quantum vacua of relativistic fields. The symmetric phase of the standard

Higher-order topological biphoton corner states in two-dimensional photonic lattices
Physical Review Research, 2022 Higher-order topological insulators have attracted great interest for their unconventional bulk-boundary correspondence especially gapless corner states. Here, we realize topological biphoton corner states in two-dimensional lattices.

Topological Insulators and Superconductors from String Theory
, 2010 Topological insulators and superconductors in different spatial dimensions and with different discrete symmetries have been fully classified recently, revealing a periodic structure for the pattern of possible types of topological insulators and ...

, 2013 The recent discovery of a new class of materials, the so-called topological insulators [1–5]. has generated a great interest in the fields of condensed matter physics and materials science [1]. In principle, according to their band structure, compounds can be divided into metals and insulators.

Electron Correlation Effects on Topological Phases
, 2014 Topological insulators are found in materials that have elements with strong spin orbit interaction. However, electron Coulomb repulsion also potentially generates the topological insulators as well as Chern insulators by the mechanism of spontaneous ...

Acoustic transport in higher-order topological insulators with Dirac hierarchy
New Journal of Physics, 2023 Dirac cones (DCs) are an important band structure in topological insulators (TIs) for realizing topological phase transition, and they provide unique ways to artificially regulate wave transport.

Holographic classification of Topological Insulators and its 8-fold periodicity
, 2012 Using generic properties of Clifford algebras in any spatial dimension, we explicitly classify Dirac hamiltonians with zero modes protected by the discrete symmetries of time-reversal, particle-hole symmetry, and chirality.
