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…

Transitions and Critical Divergences in Periodically Hopping Modulated Su-Schrieffer-Heeger Chains
Surajit Mandal, Satyaki Kar
We use a curvature renormalization group (CRG) approach to study the topological phase transitions in a Su-Schrieffer-Heeger chain and its extensions coming from periodic hopping m…

Quantum Tunneling-induced Hybridization and Coherent Dynamics of Jackiw-Rebbi Zero Modes in a Modified Su-Schrieffer-Heeger Chain
Surajit Mandal
We investigate analytically and numerically the tunneling-induced hybridization and coherent dynamics of Jackiw-Rebbi (JR) zero modes in a modified Su-Schrieffer-Heeger (SSH) model…
