Antikink dispersions of the - sawtooth spin-1/2 anisotropic Heisenberg antiferromagnetic chain
Susobhan Paul, Asim Kumar Ghosh
Antikink dispersion of the asymmetric - sawtooth spin-1/2 anisotropic Heisenberg antiferromagnetic chain has been derived. Value of spin-gap is obtained by estimating the…
Tight-binding dispersion of the prismatic pentagonal lattice
Susobhan Paul, Asim Kumar Ghosh
Tight-binding Hamiltonian on the prismatic pentagonal lattice is exactly solved to obtain the analytic expressions of dispersion relations and eigenvectors. This lattice is made of…
Ground state properties of the bond alternating spin- anisotropic Heisenberg chain
S. Paul, A. K. Ghosh
Ground state properties, dispersion relations and scaling behaviour of spin gap of a bond alternating spin- anisotropic Heisenberg chain have been studied where the ex…
Multiple gaps in the tight-binding band of a pentagonal lattice
Susobhan Paul, Asim Kumar Ghosh
Multiple gaps in the tight-binding band of a pentagonal lattice are found. Unlike the Cairo pentagonal lattice this lattice is made of irregular pentagons with arms of different le…
