The metrizability of L-topological groups
Journal of the Egyptian Mathematical Society, 2013 In this study, we study the metrizability of the notion of L-topological group defined by Ahsanullah 1988. We show that for any (separated) L-topological group there is an L-pseudo-metric (L-metric), in sense of Gähler which is defined using his notion ...

Advanced Materials, EarlyView.A sandwich‐like device for stick‐slip perception is developed, featuring a deformable bioinspired ridge layer with capability of lateral deformation and fast recovery. Coupled with magnetized functionality, the morphological transformation is capable to induce periodical electrical pulses which allows to revisit the stick‐slip process when human ...

Topological axion electrodynamics and 4-group symmetry
Physics Letters B, 2021 We study higher-form symmetries and a higher group in the low energy limit of a (3+1)-dimensional axion electrodynamics with a massive axion and a massive photon.

Flexible 3D Kirigami Probes for In Vitro and In Vivo Neural Applications
Advanced Materials, EarlyView.A customizable and scalable approach to fabricate flexible 3D kirigami microelectrode arrays (MEAs) featuring up to 128 shanks, including surface and penetrating electrodes designed to interact with the 3D space of neural tissue, is presented. The 3D kirigami MEAs are successfully deployed in several neural applications, both in vitro and in vivo, and ...

1D Magnetic Topological Inorganic Electrides
Advanced Materials, EarlyView.A series of 1D stable magnetic inorganic electrides are identified by high throughput screening and experimental synthesis. Furthermore, these 1D inorganic electrides exhibit various applications, including spintronics, topological electronics, low work function, electron emission, and high‐performance catalysts for NH3 reductions.

Topological Phases Protected by Point Group Symmetry
Physical Review X, 2017 We consider symmetry-protected topological (SPT) phases with crystalline point group symmetry, dubbed point group SPT (pgSPT) phases. We show that such phases can be understood in terms of lower-dimensional topological phases with on-site symmetry and ...

Group structures of a function spaces with the set-open topology [PDF]
arXiv, 2017 In this paper, we find at the properties of the family lambda which imply that the function space C(X,R^alpha) with the lambda-open topology is a semitopological group (paratopological group, topological group, topological vector space and other algebraic structures) under the usual operations of addition and multiplication (and multiplication by ...

Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe2
Advanced Materials, EarlyView.This study introduces the first discovery of a new local strain indicator, A2′′(Γ)$A_2^{^{\prime\prime}}( \Gamma )$ mode, for monolayer WSe2‐based excitonic applications including single photon emitter by using tip‐enhanced Raman spectroscopy. The correlative investigation with density functional perturbation theory provides the origin of the anomalous
