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 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…
Field-induced disorder in a gapped spin system with non-magnetic impurities
H. -J. Mikeska, Asimkumar Ghosh, A. K. Kolezhuk
We study S=1/2 dimers which are weakly coupled by three-dimensional antiferromagnetic interactions J'. It is commonly known that doping with non-magnetic impurities immediately ind…
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…
Spin dynamics of a one-dimensional spin-1/2 fully anisotropic Ising-like antiferromagnet in a transverse magnetic field
Asimkumar Ghosh
We consider the one-dimensional Ising-like fully anisotropic S=1/2 Heisenberg antiferromagnetic Hamiltonian and study the dynamics of domain wall excitations in the presence of tra…
Hubbard model with bond-charge interaction on a triangular lattice: a renormalization group study
Bibhas Bhattacharyya, Shreekantha Sil
We have studied the Hubbard model with bond-charge interaction on a triangular lattice for a half-filled band. At the point of particle-hole symmetry the model could be analyzed in…
Exact ground and excited states of a t-J ladder doped with two holes
Indrani Bose, Saurabh Gayen
A two chain ladder model is considered described by the strong coupling Hamiltonian. For the case of two holes moving in a background of antiferromagnetical…
