Finite frequency current noise in the Holstein model
We investigate the effects of local vibrational excitations in the nonsymmetrized current noise S(ω) of a nanojunction. For this purpose, we analyze a simple model the Holstein model in which the junction is described by a single electronic level that is coupled to two metallic leads and to a single vibrational mode. Using the Keldysh Green’s function technique, we calculate the nonsymmetrized ...
متن کاملA New Model for Timing Jitter Caused by Device Noise in Current-Mode Logic Frequency Dividers
A new method for predicting timing jitter caused by device noise in current-mode logic (CML) frequency dividers is presented. Device noise transformation into jitter is modeled as a linear time-varying (LTV) process, as opposed to a previously published method, which models jitter generation as a linear time-invariant (LTI) process. Predictions obtained using the LTV method match jitter values ...
متن کاملCooper - Pair Tunneling : Counting Statistics and Frequency - Dependent Current Noise
We discuss the counting statistics and current noise associated with the double Josephson quasiparticle resonance point in a superconducting single electron transistor. The counting statistics are in general phase-dependent, despite the fact that the average current has no dependence on phase. Focusing on parameter regimes where the counting statistics have no phase-dependence, we use a general...
متن کاملMapping Service Environmental Noise Schleswig-Holstein
This contribution presents the "mapping service environmental noise Schleswig-Holstein": The main component of this web platform consists of a WebGIS with strategic noise maps ("Noise Atlas"). The system was developed in order to support the demands for the first period of the EC Environmental Noise Directive in 2007. The Noise Atlas was since then enhanced continuously, the additions include a...
متن کاملNoise Equivalent Power Optimization of Graphene- Superconductor Optical Sensors in the Current Bias Mode
In this paper, the noise equivalent power (NEP) of an optical sensor based ongraphene-superconductor junctions in the constant current mode of operation has beencalculated. Furthermore, the necessary investigations to optimize the device noise withrespect to various parameters such as the operating temperature, magnetic field, deviceresistance, voltage and current bias have been presented. By s...
