Simple route of engineering topological phases for any desired value of winding and Chern
numbers is found in the Su–Schrieffer–Heeger (SSH) model by adding a further neighbor …

In this study, a spin-1/2 extended anisotropic XY chain has been introduced in which both
time reversal and SU (2) symmetries are broken but Z 2 symmetry is preserved. Magnetic …

Magnetic and topological properties along with quantum correlations in terms of several
entanglement measures have been investigated for an antiferromagnetic (AFM) spin-1/2 XY …

Existence of nontrivial topological phases in a tight binding Haldane-like model on the
depleted Lieb lattice is reported. This two-band model is formulated by considering the …

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 …

A number of topological phases are found to emerge in the ferromagnetic Kitaev-
Heisenberg model on CaVO lattice in the presence of Dzyaloshinskii-Moriya interaction …
