Majorana bound state of a Bogoliubov-de Gennes-Dirac Hamiltonian in arbitrary dimensions [PDF]
, 2011 We study a Majorana zero-energy state bound to a hedgehog-like point defect in a topological superconductor described by a Bogoliubov-de Gennes (BdG)-Dirac type effective Hamiltonian. We first give an explicit wave function of a Majorana state by solving

On Topological Indices and Their Reciprocals
Match Communications in Mathematical and in Computer Chemistry, 2023 Summary: If \(TI(G)=\sum\limits_\gamma F(\gamma)\) is a topological index of the graph \(G \), then \(RTI(G)=\sum\limits_\gamma \frac{1}{F(\gamma)}\) is the respective reciprocal index. In contemporary mathematical chemistry, a large number of pairs \((TI,RTI)\) have been separately introduced and studied, but their mutual relations eluded attention ...

Downhill Zagreb Topological Indices of Graphs
International Journal of Analysis and Applications, 2021 Topological indices are graph invariants determined by the distance or degree of vertices of the molecular graph. Topological indices have been used effectively in chemical graph theory in explaining the structures and predicting certain physicochemical ...

Determining topological order from a local ground state correlation function
, 2011 Topological insulators are physically distinguishable from normal insulators only near edges and defects, while in the bulk there is no clear signature to their topological order.

Parasupersymmetric Quantum Mechanics and Indices of Fredholm Operators [PDF]
, 1996 The general features of the degeneracy structure of ($p=2$) parasupersymmetric quantum mechanics are employed to yield a classification scheme for the form of the parasupersymmetric Hamiltonians.

Topological properties of Graphene using some novel neighborhood degree-based topological indices
International Journal of Mathematics for Industry, 2019 Topological indices are numeric quantities that transform chemical structure to real number. Topological indices are used in QSAR/QSPR studies to correlate the bioactivity and physiochemical properties of molecule.

Topological Properties and Entropy Calculations of Aluminophosphates
Mathematics, 2023 Topological indices are invariant numerical quantities of a graph that give facts about the structure of graphs and are found to be very helpful in predicting the physical properties of aluminophosphates.

Resolving the Topological Classification of Bismuth with Topological Defects
, 2019 Bulk boundary correspondence in topological materials allows to study their bulk topology through the investigation of their topological boundary modes. However, for classes that share similar boundary phenomenology, the growing diversity of topological ...
