1/f noise in nanowires

Aveek Bid, Achyut Bora, A. K. Raychaudhuri

We have measured the low-frequency resistance fluctuations (1 mHz<f<10 Hz) in Ag nanowires of diameter 15 nm<d<200 nm at room temperatures. The power spectral density (PSD) of the…

Electrical transport in deformed nanostrips: electrical signature of reversible mechanical failure

Soumendu Datta, Debasish Chaudhuri, Tanusri Saha-Dasgupta +1

We calculate the electrical conductivity of a thin crystalline strip of atoms confined within a quasi one dimensional channel of fixed width. The conductivity shows anomalous behav…

Interactions and non-commutativity in quantum Hall systems

F G Scholtz, B Chakraborty, S Gangopadhyay +1

We discuss the role that interactions play in the non-commutative structure that arises when the relative coordinates of two interacting particles are projected onto the lowest Lan…

Charge fluctuations in coupled systems: ring coupled to a wire or ring

P. Singha Deo, P. Koskinen, M. Manninen

Coupled systems in mesoscopic regime are of interest as charge fluctuation between the sub-systems will depend on electron-electron interactions and will play a dominant role in de…

Importance of individual scattering matrix elements at Fano resonances

P. Singha Deo

Single particle resonances in quantum wires are generally Fano resonances. In case of Fano resonances, the scattering phase shift in some channels show sharp phase drops and that i…
