Electron Condensation in a Jellium Coupled to a Finite Photonic Cavity
Pritha Mondal, Subham Kumar Saha, Awadhesh Narayan +1
We describe the process of electron condensation into a localized state in a structureless jellium that is coupled to a finite cavity. It is shown that there exists a temperature T…
Observation of excess resistance anomaly at resistive transitions in Ag/Au nanostructures
Phanibhusan S Mahapatra, Subham Kumar Saha, Rekha Mahadevu +8
The resistive transition in nanocomposite films of silver (Ag) nanoclusters of ~ 1 nm diameter embedded in gold (Au) matrix exhibits an anomalous resistance peak at the onset of th…
Current-voltage characteristics in Ag/Au nanostructures at resistive transitions
Saurav Islam, Rekha Mahadevu, Subham Kumar Saha +7
Transitions to immeasurably small electrical resistance in thin films of Ag/Au nanostructure-based films have generated significant interest because such transitions can occur even…
Unconventional Optical Response in Engineered Au-Ag Nanostructures
Dev Kumar Thapa, Subham Kumar Saha, Biswajit Bhattacharyya +3
This article describes the optical properties of nanostructures composed of silver particles embedded into a gold matrix. In previous studies these materials were shown to exhibit…
Coexistence of Diamagnetism and Vanishingly Small Electrical Resistance at Ambient Temperature and Pressure in Nanostructures
Dev Kumar Thapa, Saurav Islam, Subham Kumar Saha +7
The great practical utility has motivated extensive efforts to discover ultra-low resistance electrical conductors and superconductors in ambience. Here we report the observation o…
