Charge Modulation in the Vortex Halo of a Superconductor Enhances its Critical Magnetic Field
Anurag Banerjee, Catherine Pépin, Nandini Trivedi +1
When an orbital magnetic field suppresses superconductivity, forming periodic vortices in type-II superconductors, subdominant orders can emerge in the vortex cores. Rather than co…
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,…
