Fidelity susceptibility of Su-Schrieffer-Heeger model with further neighbour hopping term
Surajit Mandal, Asim Kumar Ghosh
In this study, topological phase transition in Su-Schrieffer-Heeger (SSH) model with a further neighbour hopping term has been studied in terms of fidelity susceptibility. Topologi…
Exotic topological phases in polyacene chains
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…
Floquet topological phases of higher winding numbers in extended Su-Schrieffer-Heeger model under quenched drive
Rittwik Chatterjee, Asim Kumar Ghosh
In this study topological properties of static and dynamic Su-Schrieffer-Heeger models with staggered further neighbor hopping terms of different extents are investigated. Topologi…
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…
Topological phases of monolayer and bilayer depleted Lieb lattices
Arghya Sil, Asim Kumar Ghosh
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 near…
