Quasi-one dimensional graphite ribbon structures in presence of magnetic field and on-site Coulomb correlation at half-filling

Jayeeta Chowdhury, Shreekantha Sil, S. N. Karmakar +1

We have presented the role of the Coulomb interaction () and the magnetic field () on the ground state properties of the quasi-one dimensional graphite ribbon structure…

Effect of external electric field on the charge density waves in one dimensional Hubbard superlattices

Jayeeta Chowdhury, S. N. Karmakar, Bibhas Bhattacharyya

We have studied the ground state of the one dimensional Hubbard superlattice structures with different unit cell sizes in the presence of electric field. Self consistent Hartree-Fo…

Ground state phase diagram and magnetoconductance of a one-dimensional Hubbard superlattice at half-filling

Jayeeta Chowdhury, S. N. Karmakar, Bibhas Bhattacharyya

We have studied a one dimensional Hubbard superlattice with different Coulomb correlations at alternating sites for a half-filled band. Mean field calculations based on the Hartree…

Effect of Fibonacci Modulation On Superconductivity

Sanjay Gupta, Shreekantha Sil, Bibhas Bhattacharyya

We have studied finite-sized single band models with short range pairing interactions between electrons in presence of diagonal Fibonacci modulation in one dimension. Two models, n…

Fibonacci-Hubbard Chain at Zero and Finite Temperatures

Sanjay Gupta, Shreekantha Sil, Bibhas Bhattacharyya

We have studied finite-sized single band Hubbard chains with Fibonacci modulation for half filling within a mean field approximation. The ground state properties, together with the…
