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.

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 Classification and Stability of Fermi Surfaces [PDF]

, 2013
In the framework of the Cartan classification of Hamiltonians, a kind of topological classification of Fermi surfaces is established in terms of topological charges.

Colorful vortex intersections in SU(2) lattice gauge theory and their influences on chiral properties

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.

Non-linear composition and infinite conformal symmetry of topologically non-trivial solutions in $$(3+1)$$ ( 3 + 1 ) -dimensional Yang–Mills theory

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.

Index theorem on chiral Landau bands for topological fermions

, 2021
Topological fermions as excitations from multi-degenerate Fermi points have been attracting increasing interests in condensed matter physics. They are characterized by topological charges, and magnetic fields are usually applied in experiments for their ...

Low-dimensional long-range topological structure in the QCD vacuum [PDF]

, 2003
Lattice topological charge associated with Ginsparg-Wilson fermions exhibits generic topological stability over quantum ensemble of configurations contributing to the QCD path integral. Moreover, the underlying chiral symmetry leads to the suppression of
