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…
Controlled engineering of extended states in disordered systems
Alberto Rodriguez, Arunava Chakrabarti, Rudolf A. Römer
We describe how to engineer wavefunction delocalization in disordered systems modelled by tight-binding Hamiltonians in d>1 dimensions. We show analytically that a simple product s…
Staggered and extreme localization of electron states in fractal space
Biplab Pal, Arunava Chakrabarti
We present exact analytical results revealing the existence of a countable infinity of unusual single particle states, which are localized with a multitude of localization lengths…
Interplay of magnetic field and geometry in magneto-transport of mesoscopic loops with Rashba and Dresselhaus spin-orbit interactions
Shreekantha Sil, Santanu K. Maiti, Arunava Chakrabarti
Electronic transport in closed loop structures is addressed within a tight-binding formalism and in the presence of both the Rashba and Dresselhaus spin-orbit interactions. It has…
