Excess Noise in Biased Superconducting Weak Links
J. P. Hessling, V. S. Shumeiko, Yu. M. Galperin +1
Non-equilibrium excess noise of a short quasi one-dimensional constriction between two superconductors is considered. A general expression for the current-current correlation funct…

Flicker Noise Induced by Dynamic Impurities in a Quantum Point Contact
J. P. Hessling, Yu. Galperin
We calculate low-frequency noise (LFN) in a quantum point contact (QPC) which is electrostatically defined in a 2D electron gas of a GaAs-AlGaAs heterostructure. The conventional s…

Noise in a Quantum Point Contact due to a Fluctuating Impurity Configuration
J. P. Hessling, Yu. Galperin, M. Jonson +2
We propose a theoretical model for the low-frequency noise observed in a quantum point contact (QPC) electrostatically defined in the 2D electron gas at a GaAs-AlGaAs interface. In…
