CEP-stable Tunable THz-Emission Originating from Laser-Waveform-Controlled Sub-Cycle Plasma-Electron Bursts [PDF]

, 2015
We study THz-emission from a plasma driven by an incommensurate-frequency two-colour laser field. A semi-classical transient electron current model is derived from a fully quantum-mechanical description of the emission process in terms of sub-cycle field-

Stationary and transient leakage current in the Pauli spin blockade

, 2009
We study the effects of cotunneling and a non-uniform Zeeman splitting on the stationary and transient leakage current through a double quantum dot in the Pauli spin blockade regime.

Labeless and reversible immunosensor assay based upon an electrochemical current-transient protocol [PDF]

, 2003
A novel labeless and reversible immunoassay based upon an electrochemical current-transient protocol is reported which offers many advantages in comparison to classical immuno-biochemical analyses in terms of simplicity, speed of response, reusability

Emergence of continual directed flow in Hamiltonian systems [PDF]

, 2010
We propose a minimal model for the emergence of a directed flow in autonomous Hamiltonian systems. It is shown that internal breaking of the spatio-temporal symmetries, via localised initial conditions, that are unbiased with respect to the transporting ...

Excitation control of variable speed pumped storage unit for electromechanical transient modeling

Energy Reports, 2022
In this paper, a new excitation control of variable speed pumped storage unit (VSPS) for electromechanical transient modeling is presented. Compared with the traditional VSPS excitation control based on current source, the inner loop control of rotor ...

Ion-Beam Induced Current in High-Resistance Materials [PDF]

, 2000
The peculiarities of electric current in high-resistance materials, such as semiconductors or semimetals, irradiated by ion beams are considered. It is shown that after ion--beam irradiation an unusual electric current may arise directed against the ...

Simulation of Voltage-source Four-quadrant Converter and It’s Control System Based on Switching Function

机车电传动, 2011
The mathematic model of voltage-source four-quadrant converter was built based on switching function, and with the transient current control method, the simulating model of converter and control system was established. Steady-state and dynamic simulation
