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…
Half-filled Hubbard ring with alternating site potentials in a magnetic field
Sanjay Gupta, Shreekantha Sil, Bibhas Bhattacharyya
We have studied a Hubbard ring with alternating site potentials for half filling in presence of a magnetic flux. Using a mean field approach we have calculated the conductivity of…
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…
