Exceptional topological insulators [PDF]
Nature Communications, 2021 AbstractWe introduce the exceptional topological insulator (ETI), a non-Hermitian topological state of matter that features exotic non-Hermitian surface states which can only exist within the three-dimensional topological bulk embedding. We show how this phase can evolve from a Weyl semimetal or Hermitian three-dimensional topological insulator close ...

Impact Sound Insulation of Thermally Insulated Balconies
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2022 AbstractWith the increasing urban densification, balconies are gaining in popularity as they improve the living quality in homes. From a technical point of view, the thermal insulation between balconies and the building’s façade is state of the art. In Germany, the most popular balcony construction is a reinforced concrete balcony, separated from the ...

Topological magnon insulator in insulating ferromagnet [PDF]
Physical Review B, 2013 In the ferromagnetic insulator with Dzyaloshinskii-Moriya interaction, we theoretically predict and numerically verify a topological magnon insulator, where the charge-free magnon is topologically protected to transport along the edge while it is insulating in the bulk.

Topologically Localized Insulators
Physical Review Letters, 2022 We show that fully-localized, three-dimensional, time-reversal-symmetry-broken insulators do not belong to a single phase of matter but can realize topologically distinct phases that are labelled by integers. The phase transition occurs only when the system becomes conducting at some filling.

Topological Insulator Metamaterials
Chemical Reviews, 2023 Confinement of electromagnetic fields at the subwavelength scale via metamaterial paradigms is an established method to engineer light-matter interaction in most common material systems, from insulators to semiconductors, from metals to superconductors.

Physical Review Letters, 2004 Recent theories predict dissipationless spin current induced by an electric field in doped semiconductors. Nevertheless, the charge current is still dissipative in these systems. In this work, we theoretically predict the dissipationless spin Hall effect, without any accompanying charge current, in some classes of band insulators, including zero-gap ...

Epitaxial growth of higher transition-temperature VO2 films on AlN/Si
APL Materials, 2016 We report the epitaxial growth and the mechanism of a higher temperature insulator-to-metal-transition (IMT) of vanadium dioxide (VO2) thin films synthesized on aluminum nitride (AlN)/Si (111) substrates by a pulsed-laser-deposition method; the IMT ...

Non-uniform Pollution Method and Pollution Flashover Characteristics of Transmission Line Insulators
Zhongguo dianli, 2019 At present, pollution of insulators in artificial contamination test is done by uniform smearing, but natural pollution, affected by wind, raining, insulator shape, pollution, pollutant particle size and other factors, is a non-uniform accumulation on ...

Fractional Topological Insulators [PDF]
Physical Review Letters, 2009 We analyze generalizations of two dimensional topological insulators which can be realized in interacting, time reversal invariant electron systems. These states, which we call fractional topological insulators, contain excitations with fractional charge and statistics in addition to protected edge modes.
