Flat bands in fractal-like geometry
Biplab Pal, Kush Saha
We report the presence of multiple flat bands in a class of two-dimensional (2D) lattices formed by Sierpinski gasket (SPG) fractal geometries as the basic unit cells. Solving the…
Tight-binding chains with off-diagonal disorder: Bands of extended electronic states induced by minimal quasi-one dimensionality
Atanu Nandy, Biplab Pal, Arunava Chakrabarti
It is shown that, an entire class of off-diagonally disordered linear lattices composed of two basic building blocks and described within a tight binding model can be tailored to g…
Complete absence of localization in a family of disordered lattices
Biplab Pal, Santanu K. Maiti, Arunava Chakrabarti
We present analytically exact results to show that, certain quasi one-dimensional lattices where the building blocks are arranged in a random fashion, can have an absolutely contin…
Engineering light localization in a fractal waveguide network
Biplab Pal, Pinaki Patra, Jyoti Prasad Saha +1
We present an exact analytical method of engineering the localization of electromagnetic waves in a fractal waveguide network. It is shown that, a countable infinity of localized e…
