Evolution of dopant-induced helium nanoplasmas [PDF]

open access: yes, 2012
Two-component nanoplasmas generated by strong-field ionization of doped helium nanodroplets are studied in a pump-probe experiment using few-cycle laser pulses in combination with molecular dynamics simulations.

Pump Built-in Hamiltonian Method for Pump-Probe Spectroscopy

open access: yes, 1999
We propose a new method of calculating nonlinear optical responses of interacting electronic systems. In this method, the total Hamiltonian (system + system-pump interaction) is transformed into a different form that (apparently) does not have a system ...

Correlation Analysis of the Hydrodynamic Characteristics and Stability of a Self-balancing Multistage Pump [PDF]

open access: yesJournal of Applied Fluid Mechanics
The BB5 series multistage centrifugal pump is commonly utilized for its capacity to deliver a large head. However, due to the long rotor system in the BB5 series multistage pump, the unsteady flow field structure of each impeller at every stage ...
