Neveu--Schwarz Irregular Vertex Operators, Decomposition Theorems, and Bilinear Operators
Hajime Nagoya
We construct rank-zero irregular vertex operators for the Neveu--Schwarz algebra as linear maps between irregular Verma modules of the same rank satisfying the usual superconformal…

Electrostatic Screening Modulation of Graphene's Electronic Structure and the Helical Wavefunction Dominated Topological Properties
Yaorui Tan, Xiang Chen, Yunhu Zhu +4
This study examines electrostatic screening effects in graphene using tight binding calculations based on the Binding energy and Bond Charge model and a modified version of it. The…
