Engineering complete delocalization of single particle states in a class of one dimensional aperiodic lattices: a quantum dynamical study
Sougata Biswas, Arunava Chakrabarti
We study quantum dynamics of a wave packet on a class of one dimensional decorated aperiodic lattices, described within a tight binding formalism. We look for the possibility of fi…

Complete escape from localization on a hierarchical lattice: A Koch fractal with all states extended
Sougata Biswas, Arunava Chakrabarti
An infinitely large Koch fractal is shown to be capable of sustaining only extended, Bloch-like eigenstates, if certain parameters of the Hamiltonian describing the lattice are num…

Designer quantum states on a fractal substrate: compact localization, flat bands and the edge modes
Sougata Biswas, Arunava Chakrabarti
Compact localized single particle eigenstates on a deterministic fractal substrate, modelled by a triangular Sierpinski gasket of arbitrarily large size, are unravelled and examine…
