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,…
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…
