Dynamic stark control of photochemical processes.
A method is presented for controlling the outcome of photochemical reactions by using the dynamic Stark effect due to a strong, nonresonant infrared field. The application of a precisely timed infrared laser pulse reversibly modifies potential energy barriers during a chemical reaction without inducing any real electronic transitions. Dynamic Stark control (DSC) is experimentally demonstrated f...
متن کاملDynamic Cache Splitting
A novel hardware for cache management that we call split cache is presented. With some help from the compiler, a program can dynamically split the cache in several caches of any size that is power of two, and choose in which cache each data element is mapped. When properly used, this scheme can reduce the connict misses near to zero. Moreover, as the total capacity of the original cache is used...
متن کاملDynamic Stark effect and forbidden-transition spectral lineshapes
We report on an experimental and theoretical study of the dynamic (ac) Stark effect on a forbidden transition. A general framework for parameterizing and describing off-resonant ac-Stark shifts is presented. A model is developed to calculate spectral line shapes resulting from resonant excitation of atoms in an intense standing light-wave in the presence of off-resonant ac-Stark shifts. The mod...
متن کاملCalculations and Measurements of the Dynamic Stark Effect in Hydrogen
A theory is given for the spectral profile of the first hydrogen Balmer line when the radiating neutral atom is under influence of both (quasi-) static and harmonically oscillating electric fields. Profiles, measured in a turbulent heating experiment, show a series of intensity maxima on the wings of the Balmer lines. If we assume a model for the spatial distribution of turbulent wave vectors, ...
متن کاملLighting the Landscape: Molecular Events Under Dynamic Stark Shifts
A new perspective on how to manipulate molecules by means of very strong laser pulses is emerging with insights from the so-called light-induced potentials, which are the adiabatic potential energy surfaces of molecules severely distorted by the effect of the strong field. Different effects appear depending on how the laser frequency is tuned, to a certain electronic transition, creating light-...
