Magnetism, electronic transport, and disorder in strongly correlated systems
Joel Bobadilla
This thesis investigates the magnetic, spectral, and transport properties of strongly correlated electronic systems, with a primary focus on the Hubbard model and its extensions re…
A Correlated Route to Antiferromagnetic Spintronics
Joel Bobadilla, Alberto Camjayi
Antiferromagnets are attractive for spintronics owing to their vanishing net magnetization and ultrafast spin dynamics, yet their spin-compensated electronic structure has long con…
Magnetoresistivity in the Antiferromagnetic Hubbard Model
Joel Bobadilla, Marcelo J. Rozenberg, Alberto Camjayi
We investigate the magnetotransport properties of the half-filled antiferromagnetic (AF) one-band Hubbard model under an external magnetic field using the single-site dynamical mea…
Disordered Mott-Hubbard Physics in Nanoparticle Solids: Persistent Gap Across the Disorder-localized-to-Mott-localized Transition
Davis Unruh, Alberto Camjayi, Chase Hansen +3
We show that Nanoparticle (NP) solids are an exciting platform to seek new insights into the disordered Mott-Hubbard physics. We developed a "Hierarchical Nanoparticle Transport Si…
