This research was conducted in the courtyard of Lau Dendang Village, Medan, North Sumatra. Which is carried out from October to November. study manufacture compost using vermicomposting method which utilizes organic waste such as rotting vegetables and determine differences growth rates applying water mustard greens. The results this indicate that application vegetable has an impact on p...

We derive frequency moment sum rules for the retarded electronic Green's function and self-energy of the Holstein model for both equilibrium and nonequilibrium cases. We also derive sum rules for the phonon propagator in equilibrium and nonequilibrium. These sum rules allow one to benchmark nonequilibrium calculations and help with interpreting the behavior of electrons driven out of equilibriu...

We propose an experimental scheme to verify the quantum nonequilibrium fluctuation relations using current technology. Specifically, we show that the characteristic function of the work distribution for a nonequilibrium quench of a general quantum system can be extracted by Ramsey interferometry of a single probe qubit. Our scheme paves the way for the full characterization of nonequilibrium pr...

The general problem of representing the Greens function G(k,z) in terms of self-energy in field theories lacking Wick’s theorem is considered. A simple construction shows that a Dyson-like representation with a self-energy !(k,z) is always possible, provided we start with a spectral representation for G(k,z) for finite-sized systems and take the thermodynamic limit. The self-energy itself can t...

The intense investigations of molecular devices, as an alternative to standard electronics components, underlines the need to model the conduction mechanisms of nano-scale conductors. In addition to measurements of the elastic conductance through point-contacts, atomic-wires and molecules, recent experiments have shown inelastic tunneling currents through, for example, a hydrogen molecule attac...

Energy dissipation in a nonequilibrium steady state is studied in driven quantum Langevin systems. We analyze a characteristic function that generates energy dissipation flow to thermal environment. This function gives a general formula for the average rate of energy dissipation using an autocorrelation function for the system variable. This leads to a general expression of the equality that co...

Nonequilibrium response spectroscopy is a novel method of analyzing the molecular kinetics of voltage-sensitive proteins that involves measuring of the nonequilibrium response of the molecules to fluctuating fields with large amplitudes and frequencies. This response is exquisitely sensitive to features of the kinetics that are difficult or impossible to resolve by means of more traditional rel...
