Non-Hermitian Topology in Hermitian Topological Matter [PDF]
Phys. Rev. Lett. 133, 266604 (2024)Non-Hermiticity gives rise to distinctive topological phenomena absent in Hermitian systems. However, connection between such intrinsic non-Hermitian topology and Hermitian topology has remained largely elusive. Here, considering the bulk and boundary as an environment and system, respectively, we demonstrate that anomalous boundary states in Hermitian

Nihon Kikai Gakkai ronbunshu, 2019 This paper proposes a novel topology optimization method for unsteady state incompressible Navier-Stokes flow. Many methods of topology optimization for steady state flow have been proposed, whereas most fluid flow problems should be considered as ...

Topological gravity on surfaces with boundaries
Physics Letters B, 1990 Abstract In this letter we investigate the effects of boundaries in topological gravity. This is done by the insertion of appropriate vertex operators. We indicate how the correlation functions are determined and discuss the example of the disk.

Exploring Landmark Placement Strategies for Topology-Based Localization in Wireless Sensor Networks
EURASIP Journal on Advances in Signal Processing, 2008 In topology-based localization, each node in a network computes its hop-count distance to a finite number of reference nodes, or “landmarksâ€Â.

Time-reversal-invariant C_{2}-symmetric higher-order topological superconductors
Physical Review Research, 2020 We propose a minimal lattice model for two-dimensional class DIII superconductors with C_{2}-protected higher-order topology. Although this class of superconductors cannot be topologically characterized by symmetry eigenvalues at high-symmetry momenta ...

Bulk-boundary correspondence in point-gap topological phases
A striking feature of non-Hermitian systems is the presence of two different types of topology. One generalizes Hermitian topological phases, and the other is intrinsic to non-Hermitian systems, which are called line-gap topology and point-gap topology ...

Topological grain boundary segregation transitions
ScienceEngineering the structure of grain boundaries (GBs) by solute segregation is a promising strategy to tailor the properties of polycrystalline materials. Solute segregation triggering phase transitions at GBs has been suggested theoretically to offer different pathways to design interfaces, but an understanding of their intrinsic atomistic nature is ...
