Topological insulators with hybrid-order boundary states
Physical Review BWe report the discovery of several classes of novel topological insulators (TIs) with hybrid-order boundary states generated from the first-order TIs with additional crystalline symmetries. Unlike the current studies on hybrid-order TIs where different-order topology arises from merging different-order TIs in various energy, {\color{red} these novel ...

Direct Evidence of Topological Dirac Fermions in a Low Carrier Density Correlated 5d Oxide
Advanced Functional Materials, EarlyView.The 5d oxide BiRe2O6 is discovered as a low‐carrier‐density topological semimetal hosting symmetry‐protected Dirac fermions stabilized by nonsymmorphic symmetries. Angle‐resolved photoemission spectroscopy, quantum oscillations, and magnetotransport measurements reveal gapless Dirac cones, quasi‐2D Fermi surfaces, high carrier mobility, and a field ...

A distributional representation of strip analytic functions
International Journal of Mathematics and Mathematical Sciences, 1982 A strip analytic function converging in the D′ topology to certain boundary values (from the interior of the strip) is represented as the difference of two generalized Cauchy integrals.

Solvable Topological Boundaries
, 2019 The hallmark of topological phases of matter is the presence of robust boundary states. In this dissertation, a formalism is developed with which analytical solutions for these states can be straightforwardly obtained by making use of destructive interference, which is naturally present in a large family of lattice models. The validity of the solutions

Analysis and Geometry in Metric Spaces, 2016 We consider a ‘contracting boundary’ of a proper geodesic metric space consisting of equivalence classes of geodesic rays that behave like geodesics in a hyperbolic space.We topologize this set via the Gromov product, in analogy to the topology of the ...

Topological divisors of zero and Shilov boundary
Topology and its Applications, 2006 Let \(L\) be a non-archimedean and non-trivially complete valued field, let \((A, \|. \| )\) be a commutative normed \(L\)-algebra with unity, and let \(\|.\| _{si}\) be the spectral seminorm of \(A\) defined by \(\| x \| _{si}:= \lim_{n} \| x^n \| ^{1/n}\). The Shilov boundary of \(A\) is the smallest among all the subsets \(F\) of Mult\((A,\|.

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance
Advanced Functional Materials, EarlyView.Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...
