P6322-type SrNiIO6: An ideal half-metallic candidate with a fully spin-polarized Weyl complex

Results in Physics, 2023
Researchers are interested in magnetic topological materials because they can integrate magnetic and topological properties. Using the first-principles calculations, we identify the P6322-type SrNiIO6 as a dynamically stable half-metallic candidate with ...

Estimating topological charge of propagating vortex from single-shot non-imaged speckle

Chinese Optics Letters (COL), 2021
Encoding information using the topological charge of vortex beams has been proposed for optical communications. The conservation of the topological charge on propagation and the detection of the topological charge by a receiver are significant in these ...

Topological electric charge [PDF]

International Journal of Theoretical Physics, 1995
By treating magnetic charge as a gauge symmetry through the introduction of a ``magnetic'' pseudo four-vector potential, it is shown that it is possible, using the 't Hooft-Polyakov construction, to obtain a topological electric charge. The mass of this electrically charged particle is found to be on the order of {1 / 137} M_W as opposed to the much ...

Unusual competition of superconductivity and charge-density-wave state in a compressed topological kagome metal [PDF]

Nature Communications, 2021
Understanding the competition between superconductivity and other ordered states (such as antiferromagnetic or charge-density-wave (CDW) state) is a central issue in condensed matter physics. The recently discovered layered kagome metal AV3Sb5 (A = K, Rb,

A charge-density-wave topological semimetal [PDF]

Nature Physics, 2021
Topological physics and strong electron-electron correlations in quantum materials are typically studied independently. However, there have been rapid recent developments in quantum materials in which topological phase transitions emerge when the single-particle band structure is modified by strong interactions.

Perfect Lattice Topology: The Quantum Rotor as a Test Case [PDF]

, 1997
Lattice actions and topological charges that are classically and quantum mechanically perfect (i.e. free of lattice artifacts) are constructed analytically for the quantum rotor.

Topological charges of fullerenes

Journal of Mathematical Chemistry, 2022
AbstractWe defined the topological charge and bump number for fullerenes. All even fullerene isomers from $$C_{20}$$ C 20 up to $$C_{70}$$ C 70 were constructed ...

Towards a quantum theory of solitons

Nuclear Physics B, 2015
We formulate a quantum coherent state picture for topological and non-topological solitons. We recognize that the topological charge arises from the infinite occupation number of zero momentum quanta flowing in one direction.

Topological classes of thermodynamics of the static multi-charge AdS black holes in gauged supergravities: novel temperature-dependent thermodynamic topological phase transition [PDF]

Journal of High Energy Physics
In this paper, we investigate, in the framework of the topological approach to black hole thermodynamics, using the generalized off-shell Helmholtz free energy, the topological numbers of the static multi-charge AdS black holes in four- and five ...
