Topological phases of polyacenes
Rakesh Kumar Malakar, Asim Kumar Ghosh
The introduction of Su-Schrieffer-Heeger model has led to a major breakthrough in the area of one-dimensional topological insulators, even though this model was primarily formulate…
Magnetic phases of XY model with three-spin terms: interplay of topology and entanglement
Rakesh Kumar Malakar, Asim Kumar Ghosh
Magnetic and topological properties along with quantum correlations in terms of several entanglement measures have been investigated for an antiferromagnetic spin-1/2 XY model in t…
Quantum phases of spin-1/2 extended XY model in transverse magnetic field
Rakesh Kumar Malakar, Asim Kumar Ghosh
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 symmetry is preserved. Magnetic an…
Engineering topological phases of any winding and Chern numbers in extended Su-Schrieffer-Heeger models
Rakesh Kumar Malakar, Asim Kumar Ghosh
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 hopp…
