Observation of an Alice ring in a Bose–Einstein condensate
Nature Communications, 2023 Monopoles and vortices are fundamental topological excitations that appear in physical systems spanning enormous scales of size and energy, from the vastness of the early universe to tiny laboratory droplets of nematic liquid crystals and ultracold gases.

Computing Wiener and Hyper-Wiener Indices of Zero-Divisor Graph of ℤℊ3×ℤI1I2
Journal of Function Spaces, 2022 Let S=ℤℊ3×ℤI1I2 be a commutative ring where ℊ,I1 and I2 are positive prime integers with I1≠I2. The zero-divisor graph assigned to S is an undirected graph, denoted as YS with vertex set V(Y(S)) consisting of all Zero-divisor of the ring S and for any c,

Generation of Terahertz Superimposed Perfect Vortex Beams
IEEE Photonics Journal, 2021 A terahertz (THz) superimposed perfect vortex (SPV) beam is generated by using a designed superimposed optimal phase element (SOPE) at 0.3 THz. As the superimposed topological charge changes, the ring radius of THz SPV beams remains almost constant in ...

The largest topological ring of functions endowed with the m-topology
Applied General Topology, 2022 The purpose of this article is to identify the largest subring of the ring of all real valued functions on a Tychonoff space X, which forms a topological ring endowed with the m-topology.

Pareto vectors of continuous linear operators
Journal of Inequalities and Applications, 2023 The intersection of all zero-neighborhoods in a topological module over a topological ring is a bounded and closed submodule whose inherited topology is the trivial topology.
