QED theory of the multiphoton cascade transitions in atoms
QED theory the multiphoton cascade transitions atoms Atomic Physics
2012/4/20
QED theory of multiphoton cascade transitions in atoms and ions is developed. This theory allows for the accurate description of the process important for astrophysical studies of the cosmological hyd...
Optical transitions in highly-charged californium ions with high sensitivity to variation of the fine-structure constant
Optical transitions highly-charged californium ions variation of the fine-structure constant Atomic Physics
2012/4/19
We study electronic transitions in highly-charged Cf ions that are within the frequency range of optical lasers and have very high sensitivity to potential variations in the fine-structure constant, a...
Structural phase transitions in multipole traps
Structural phase transitions multipole traps
2012/2/28
A small number of laser-cooled ions trapped in a linear radiofrequency multipole trap forms a hollow tube structure. We have studied, by means of molecular dynamics simulations, the structural transit...
A fast Variational Gaussian Wave-packet method: Size-induced structural transitions in large neon clusters
Variational Gaussian Wave-packet method Size-induced structural transitions large neon clusters
2011/8/17
Abstract: The Variational Gaussian wavepacket (VGW) method is an alternative to Path Integral Monte-Carlo (PIMC) for the computation of thermodynamic properties of many-body systems at thermal equilib...

2011/9/5
We present the first clear identification and highly accurate measurement of the intra-shell transition 1s2p 3P2 ! 1s2s 3S1 of He-like uranium performed via X-ray spectroscopy.The present experiment h...
Atomic parity violation in 0-to-0 two-photon transitions
0-to-0 two-photon transitions Atomic parity
2011/9/2
We present a method for measuring atomic parity violation in the absence of static external electric and magnetic elds. Such measurements can be achieved by observing the interference of parity conse...
Nuclear effects in atomic transitions
isotope shifts, hyperfine splitting, dielectronic recombination, nuclear polarization, atomic parity violation,highly charged ions
2011/9/2
Atomic electrons are sensitive to the properties of the nucleus they are bound to, such as nuclear mass,charge distribution, spin, magnetization distribution, or even excited level scheme. These nucle...
Theoretical Investigations on Valence Vibronic Transitions
Theoretical Investigations Valence Vibronic Transitions
2010/10/15
This article reviews previously employed methods to study several valence electronic transitions, optically forbidden or not, enhancing intensity through vibronic coupling. Electronic transition dipol...
