A TOPOLOGICAL INTERPRETATION OF THE COLOR CHARGE [PDF]
Modern Physics Letters A, 2007 We develop a theory on a topologically nontrivial manifold which leads to different vacuum backgrounds at the field level. The different colors of the same quark flavor live in different backgrounds generated by the action of the torsion subgroup of H2(M, 2πℤ) on H2(M, 2πℤ) itself.

Topological charge of a superposition of identical parallel single-ringed Laguerre-Gaussian beams
Компьютерная оптика, 2022 We study a superposition of several identical parallel single-ringed Laguerre-Gaussian beams. Both for the initial plane and for the far field, we show analytically and confirm numerically that if the weighting coefficients of the superposition are real ...

Biasing topological charge injection in topological matter [PDF]
Physical Review B, 2021 We explore the interplay between topologies in the momentum and real spaces to formulate a thermodynamic description of nonequilibrium injection of topological charges under external bias. We show that the edge modes engendered by the momentum-space topology can play a functional role of connecting the external reservoirs to the bulk transport of ...

Higher topological charge and the QCD vacuum
Physical Review Research, 2020 It is shown that gauge field configurations with higher topological charge modify the structure of the QCD vacuum, which is reflected in its dependence on the CP-violating topological phase θ.

Electrically charged topological solitons [PDF]
Nuclear Physics B, 2001 Two new families of T-Dual integrable models of dyonic type are constructed. They represent specific $A_n^{(1)}$ singular Non-Abelian Affine Toda models having U(1) global symmetry. Their 1-soliton spectrum contains both neutral and U(1) charged topological solitons sharing the main properties of 4-dimensional Yang-Mills-Higgs monopoles and dyons.

Topological Charges of Periodically Kicked Molecules
Physical Review Letters, 2023 We show that the simplest of existing molecules -- closed-shell diatomics not interacting with one another -- host topological charges when driven by periodic far-off-resonant laser pulses. A periodically kicked molecular rotor can be mapped onto a ''crystalline'' lattice in angular momentum space.

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 ...

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 ...

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.
