Effects of gold cluster intercalation in graphene: stationary waves and modified QPI features
Cristina Bena, Marion Cranney, Poonam Kumari +2
The paper investigates how gold atoms intercalated beneath epitaxial graphene on SiC create cluster-induced scattering that generates distinctive standing-wave patterns and modifie…
An iterative method bridging DFT, disorder averaging, and experiment in intercalated materials: application to Au-intercalated graphene
Poonam Kumari, Alberto Zobelli, Igor de Melo Froldi +3
The paper presents an iterative approach that combines density functional theory, tight‑binding modeling, disorder averaging via the self‑consistent T‑matrix approximation, and ARP…
Quasiparticle interference and spectral function of the UTe superconductive surface band
Adeline Crépieux, Emile Pangburn, Shuqiu Wang +7
We compute the (0-11) surface spectral function, the surface density of states (DOS), and the quasiparticle interference (QPI) patterns, both in the normal state and superconductin…
Odd-Parity Quasiparticle Interference in the Superconductive Surface State of UTe2
Shuqiu Wang, Kuanysh Zhussupbekov, Joseph P. Carroll +13
Although no known material exhibits intrinsic topological superconductivity, wherein spin-triplet odd-parity electron pairing occurs, UTe2 is now the leading representative of this…
Probing quasiparticle excitations in a doped Mott insulator via Friedel oscillations
Anurag Banerjee, Emile Pangburn, Catherine Pépin +1
In this work, we investigate impurity-induced Friedel oscillations in the doped two-dimensional Hubbard model, focusing on the role of holon and doublon excitations. We show that w…
Impurity-induced Mott ring states and Mott zeros ring states in the Hubbard operator formalism
Emile Pangburn, Anurag Banerjee, Catherine Pépin +1
We study the formation of subgap impurity states in strongly correlated Mott insulators. We use a composite operator method that gives us access to both the bulk Green's function,…
