WebWe propose general topological order parameters for interacting insulators in terms of the Green’s function at zero frequency. They provide a uniﬁed description of various interacting topological insulators including the quantum anomalous Hall insulators and the time-reversal-invariant insulators in four, three, and two dimensions. WebApr 4, 2024 · The standard topological insulator is characterized by an insulating bulk and a conducting boundary, so a three dimensional insulating bulk of a topological insulator has …

WebJun 23, 2024 · Topological insulators and superconductors are characterized by their gapless boundary modes. In this paper, we develop a recursive approach to the boundary Green function, which encodes this nontrivial boundary physics. Our approach describes the various topologically trivial and nontrivial phases as fixed points of a recursion and … WebMar 8, 2024 · In addition to insulators, higher-order topological semimetals (for example, α-Cd 3 As 2) have also been proposed to host 1D hinge states 15,16.

A topological insulator is a material whose interior behaves as an electrical insulator while its surface behaves as an electrical conductor, meaning that electrons can only move along the surface of the material. A topological insulator is an insulator for the same reason a "trivial" (ordinary) insulator is: there exists an … See more The first models of 3D topological insulators were proposed by Volkov and Pankratov in 1985, and subsequently by Pankratov, Pakhomov, and Volkov in 1987. Gapless 2D Dirac states were shown to exist at the band … See more Topological insulators can be grown using different methods such as metal-organic chemical vapor deposition (MOCVD), physical vapor deposition (PVD), solvothermal … See more The physical vapor deposition (PVD) technique does not suffer from the disadvantages of the exfoliation method and, at the same time, it is much simpler and cheaper than the fully controlled growth by molecular-beam epitaxy. The PVD method … See more 2D Topological insulators were first realized in system containing HgTe quantum wells sandwiched between cadmium telluride in 2007. The first 3D … See more Spin-momentum locking in the topological insulator allows symmetry-protected surface states to host Majorana particles if superconductivity is induced on the surface of 3D topological insulators via proximity effects. (Note that Majorana zero-mode can also … See more The first step of topological insulators identification takes place right after synthesis, meaning without breaking the vacuum and moving … See more Bloch's theorem allows a full characterization of the wave propagation properties of a material by assigning a matrix to each wave vector in the Brillouin zone See more Photonic topological insulators are artificial electromagnetic materials that support topologically non-trivial, unidirectional states of light. Photonic topological phases are classical electromagnetic wave analogues of electronic topological phases studied in condensed matter physics. Similar to their electronic counterparts, they, can provide robust unidirectional channels for light propagation. tensor flow is open sourceWebZnPS3. ZnPS3 is an insulator 2D material.
