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…
Correlated Mott semi-metal in the topological heavy fermion model
Emile Pangburn, Igor de Melo Froldi, Anurag Banerjee
The topological heavy-fermion model provides a minimal framework for describing the coexistence of localized moments and itinerant Dirac electrons in magic-angle twisted bilayer gr…
Superconducting diode effect in unconventional -wave magnets
Igor de M. Froldi, Hermann Freire
We investigate the emergence of superconducting phases, both with zero and finite Cooper-pair center-of-mass momenta, in recently proposed unconventional -wave magnets. As a res…
Efficiency of the superconducting diode effect of pair-density-wave states in two-dimensional -wave altermagnets
Igor de M. Froldi, Hermann Freire
We systematically study the efficiency of the intrinsic superconducting diode effect of several pair-density-wave states that can emerge in two-dimensional -wave metallic alterm…
Large quark mass Euler-Heisenberg type action for QCD with quark sources and its Abelian limit
Igor de M. Froldi, Fabio L. Braghin
The quark determinant in the presence of a background gluon field is calculated in a large quark mass approach within a derivative expansion by considering quark sources. The resul…
Strong pair-density-wave fluctuations in an exactly solvable doped Mott insulator
Igor de M. Froldi, Carlos Eduardo S. P. Corsino, Hermann Freire
We investigate the Hatsugai-Kohmoto (HK) model on a square lattice, which describes both a Mott insulator at half-filling and a non-Fermi liquid phase on doping. Through the soluti…
