A Fibonacci atomic chain with side coupled quantum dots: crossover from a singular continuous to a continuous spectrum and related issues
Arunava Chakrabarti, Samar Chattopadhyay
Interaction of bound states with a singular continuous spectrum is studied using a one dimensional Fibonacci quasicrystal as a prototype example. Single level quantum dots are atta…
Electron states and magneto-transport in a graphene geometry with a fractal distribution of holes
Biplab Pal, Arunava Chakrabarti, Nitai Bhattacharya
We consider an infinite graphene geometry where bonds and sites have been removed selectively to map it onto an effective Sierpinski gasket comprising of hexagons. We show that suc…
A proposal for the measurement of Rashba and Dresselhaus spin-orbit interaction strengths in a single sample
Santanu K. Maiti, Shreekantha Sil, Arunava Chakrabarti
We establish an exact analytical treatment for the determination of the strengths of the Rashba and Dresselhaus spin-orbit interactions in a single sample by measuring persistent s…
On the extendedness of eigenstates in a hierarchical lattice: a critical view
Biplab Pal, Arunava Chakrabarti, Nitai Bhattacharya
We take a critical view at the basic definition of extended single particle states in a non-translationally invariant system. For this, we present the case of a hierarchical lattic…
Multi-terminal magneto-transport in an interacting fractal network: a mean field study
Santanu K. Maiti, Arunava Chakrabarti
Magneto-transport of interacting electrons in a Sierpinski gasket fractal is studied within a mean field approach. We work out the three-terminal transport and study the interplay…
Strange eigenstates and anomalous transport in a Koch fractal with hierarchical interaction
Arunava Chakrabarti
Stationary states of non-interacting electrons on a Koch fractal are investigated within a tight binding approach. It is observed that if a hierarchically long range hopping is all…
