Binding of holes and competing spin-charge order in simple and extended Hubbard model on cylindrical lattice: An exact diagonalization study
Md Fahad Equbal, M. A. H. Ahsan
We investigate the binding of holes and the emergence of competing spin-charge order in the simple and extended Hubbard model using exact diagonalization on the 3x4 cylindrical lat…
Spin-resolved Mott crossover and entanglement in the half-filled Hubbard model
Md Fahad Equbal, M. A. H. Ahsan
We investigate the interaction-driven reorganization of spin and charge correlations in finite Hubbard clusters using exact diagonalization. Focusing on half-filled and lightly dop…
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…
Probing imbalanced Weyl nodes in two-dimensional anisotropic Weyl semimetal via optical conductivity
Suheel Ahmad Malik, M. A. H. Ahshan, SK Firoz Islam
We present a theoretical investigation of the electronic band structure and optical properties of a two-dimensional anisotropic semimetal that is described by a tilted semi-Dirac t…
