Engineering edge states in two-leg SSH ladder and their topoelectric circuit realization
Anish Kuanr, Rajashri Parida, Prabhu Prasad Tripathy +2
We study the topological phase transition in a two-leg Su-Schrieffer-Heeger (SSH) ladder by redefining the unit-cell structure. For both identical hopping dimerization pattern (uni…

Reentrant topology and reverse pumping in a quasiperiodic flux ladder
Sanchayan Banerjee, Rajashri Parida, Tapan Mishra
Topological phases of matter are known to be unstable against strong onsite disorder in one dimension. In this work, however, we propose that in the case of a topological ladder, a…

Topological phase transition through tunable nearest-neighbor interactions in a one-dimensional lattice
Rajashri Parida, Diptiman Sen, Tapan Mishra
We investigate the phase diagram of a one-dimensional model of hardcore bosons or spinless fermions with tunable nearest-neighbor interactions. By introducing alternating repulsive…
