RELATIVISTIC EFFECTS IN A SYSTEM OF GRAVITATIONALLY INTERACTING NON-DUST-LIKE PARTICLES

open access: yesOdessa Astronomical Publications, 2012
The two-body problem in the Kaluza- Klein model with toroidal topology of additional spatial dimensions is investigated. The characteristic property of the considerin g gravitational field sources is the existence of tension into the compact subspace ...

How (not) to Cage an Electron: The Perfluoro Cage Effect as an Extrinsic Molecular Property

open access: yesHelvetica Chimica Acta, EarlyView.
A rigorous definition within Kohn–Sham density functional theory is presented for the notion of an caged electron inside perfluorinated fullerenes as radical anions. ABSTRACT The notion of a (molecular) electron cage was coined for the unique hosting capacity of perfluorocubane, suggesting the “encapsulation of an electron” within the highly symmetric ...

Evolution of dynamical signature in the X-cube fracton topological order

open access: yesPhysical Review Research, 2022
As an unconventional realization of topological orders with an exotic interplay of topology and geometry, fracton (topological) orders feature subextensive topological ground-state degeneracy and subdimensional excitations that are movable only within a ...

Wilson loop approach to fragile topology of split elementary band representations and topological crystalline insulators with time reversal symmetry

open access: yes, 2019
We present a general methodology towards the systematic characterization of crystalline topological insulating phases with time reversal symmetry (TRS).~In particular, taking the two-dimensional spinful hexagonal lattice as a proof of principle we study ...

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

open access: yesLaser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

On Soft Generalized Topological Spaces

open access: yesJournal of New Results in Science, 2014
– The main purpose of this paper is to introduce soft generalized topology on a soft set. The definitions of subspace soft generalized topology and soft continuity of soft functions are introduced.

Continuous isomorphisms onto separable groups

open access: yesApplied General Topology, 2012
A condensation is a one-to-one continuous function onto. We give sufficient conditions for a Tychonoff space to admit a condensation onto a separable dense subspace of the Tychonoff cube Ic and discuss the differences that arise when we deal with ...

Realization of Qi-Wu-Zhang model in spin-orbit-coupled ultracold fermions

open access: yesPhysical Review Research, 2023
Based on the optical Raman lattice technique, we experimentally realize the Qi-Wu-Zhang model for the quantum anomalous Hall phase in ultracold fermions with two-dimensional (2D) spin-orbit (SO) coupling. We develop an experimental protocol of pump-probe

Matched Topological Subspace Detector

open access: yes
Topological spaces, represented by simplicial complexes, capture richer relationships than graphs by modeling interactions not only between nodes but also among higher-order entities, such as edges or triangles. This motivates the representation of information defined in irregular domains as topological signals.
