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 charges of noncommutative soliton [PDF]
Physics Letters B, 2001 The noncommutative soliton is characterized by the use of the projection operators in non-commutative space. By using the close relation with the K-theory of $C^*$-algebra, we consider the variations of projection operators along the commutative directions and identify their topological charges.

Charge and the topology of spacetime [PDF]
Classical and Quantum Gravity, 1999 A new class of electrically charged wormholes is described in which the outer two sphere is not spanned by a compact coorientable hypersurface. These wormholes can therefore display net electric charge from the source free Maxwell's equation. This extends the work of Sorkin on non-space orientable manifolds, to spacetimes which do not admit a time ...

Journal of High Energy Physics, 2017 We introduce topological non-trivial colorful regions around intersection points of two perpendicular vortex pairs and investigate their influence on topological charge density and eigenmodes of the Dirac operator.

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 ...

European Physical Journal C: Particles and Fields, 2021 An infinite-dimensional family of analytic solutions in pure SU(2) Yang–Mills theory at finite density in $$(3+1)$$ ( 3 + 1 ) dimensions is constructed. It is labelled by two integeres (p and q) as well as by a two-dimensional free massless scalar field.

Topological charge, spin, and heat transistor [PDF]
Physical Review B, 2021 Spin pumping consists in the injection of spin currents into a non-magnetic material due to the precession of an adjacent ferromagnet. In addition to the pumping of spin the precession always leads to pumping of heat, but in the presence of spin-orbital entanglement it also leads to a charge current.
