Computation Kernel for Feynman Diagrams
Daria Gazizova, Rayan Farid, B. D. E. McNiven +3
We present a general representation for solving problems in many-body perturbation theory. By projecting the single-particle Green's function to an auxiliary space we show how one…

Graphene/hBN heterostructure based Valley transistor: Dynamic Control of valley current in synchronized nonzero voltages, within the time-dependent regime
A. Belayadi, C. I. Osuala, I. Assi +3
Graphene/hexagonal boron nitride (hBN) heterostructures represent a promising class of metal-insulator-semiconductor systems widely explored for multifunctional digital device appl…

Lifshitz transition and triplet -wave pairing from the induced ferromagnetic plaquette via spin differentiated nonlocal interaction
Rayan Farid, Daria Gazizova, B. D. E. McNiven +1
We study the two-dimensional extended Hubbard model on a square lattice and incorporate spin-differentiated nearest neighbor (NN) interactions where the equal-spin () and u…
