Energy-Weighted Site Percolation in Two Dimensions
Sayan Sircar, Kabir Ramola
We study a generalization of two-dimensional site percolation by assigning an energy cost to bonds between nearest-neighbor occupied sites. This leads to a competitio…

Topological Anderson insulator phases in one dimensional quasi-periodic mechanical SSH chains
Sayan Sircar
In this paper, we investigate the transition between topological phases in a Su-Schrieffer-Heeger (SSH) model composed of springs and masses in which the intracellular Aubry-André…

Disorder driven topological phase transitions in 1D mechanical quasicrystals
Sayan Sircar
We examine the transition from trivial to non-trivial phases in a Su-Schrieffer-Heeger model subjected to disorder in a quasi-periodic environment. We analytically determine the ph…
