Finite-size effects and interaction-driven crossovers in quarter-filled attractive Hubbard model: Exact diagonalization, DMRG and machine-learning analysis
Md Fahad Equbal, M. A. H. Ahsan, Satoru Hayami
We investigate the quarter-filled attractive Hubbard model on finite-width cylindrical lattices using exact diagonalization (ED), density-matrix renormalization group (DMRG) and un…
Emergence of correlation-driven altermagnetism in Hubbard model on geometrically frustrated lattice-clusters
Md Fahad Equbal, M. A. H. Ahsan
We investigate the emergence of correlation-driven altermagnetism in simple and extended Hubbard model on geometrically frustrated lattice-clusters using exact diagonalization. By…
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…
Derivation of the deformed Heisenberg algebra from discrete spacetime
Naveed Ahmad Shah, S. S. Z. Ashraf, Aasiya Shaikh +6
Although the deformation of the Heisenberg algebra by a minimal length has become a central tool in quantum gravity phenomenology, it has never been rigorously obtained and is ofte…
