Principal Component Analysis of Competing Correlations in Quarter-Filled Hubbard Models
Md Fahad Equbal, S R Hassan, M. A. H. Ahsan
We present an unsupervised learning analysis of correlation hierarchies in the quarter-filled simple and extended Hubbard models by applying principal component analysis (PCA) to e…
Strange-like Metallicity in a Toy Model with Selective-Mottness
M. S. Laad, S. R. Hassan
The interplay between band and atomic aspects in materials with co-existing wide-band and flat-band states, or wide-band and effectively dispersionless electronic states is increas…
Mott Criticality as the Confinement Transition of a Pseudogap-Mott Metal
Abhirup Mukherjee, S. R. Hassan, Anamitra Mukherjee +3
The phenomenon of Mott insulation involves the localization of itinerant electrons due to strong local repulsion. Upon doping, a pseudogap (PG) phase emerges - marked by selective…
Can disorder act as a chemical pressure? An optical study of the Hubbard model
Himadri Barman, Mukul S. Laad, Syed R. Hassan
The optical properties have been studied using the dynamical mean-field theory (DMFT) on a disordered Hubbard model. Despite the fact that disorder turns a metal to an insulator in…
