Magnetic field induced topological nodal-lines in triplet excitations of frustrated antiferromagnet CaV $_{4}$ O $_{9}$

Moumita Deb, Asim Kumar Ghosh

Magnetic field induced multiple non-Dirac nodal-lines are found to emerge in the triplet dispersion bands of a frustrated spin-1/2 antiferromagnetic model on the CaVO lattice. Plaq…

Antikink dispersions of the $J_{1}$ - $J_{2}$ sawtooth spin-1/2 anisotropic Heisenberg antiferromagnetic chain

Susobhan Paul, Asim Kumar Ghosh

Antikink dispersion of the asymmetric $J_{1}$ - $J_{2}$ sawtooth spin-1/2 anisotropic Heisenberg antiferromagnetic chain has been derived. Value of spin-gap is obtained by estimating the…

Ground state properties of the bond alternating spin- $\frac{1}{2}$ anisotropic Heisenberg chain

S. Paul, A. K. Ghosh

Ground state properties, dispersion relations and scaling behaviour of spin gap of a bond alternating spin- $\frac{1}{2}$ anisotropic Heisenberg chain have been studied where the ex…

Large magnetoelectric coupling in nanoscale BiFeO $_{3}$ from direct electrical measurements

Sudipta Goswami, Dipten Bhattacharya, Lynette Keeney +9

We report the results of direct measurement of remanent hysteresis loops on nanochains of BiFeO $_{3}$ at room temperature under zero and $\sim$ 20 kOe magnetic field. We noticed a sup…

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…
