Coherent Raman Spectra of the v 1 Mode of 10 BF 3 and 11 BF 3

October 12, 2021
Author(s)
Robynne Kirkpatrick, Tony Masiello, Alfons Weber, J Nibler
High resolution (0.001cm-1) coherent anti-Stokes Raman spectroscopy (CARS) was used to directly examine the n1 symmetric stretching mode of the planar symmetric D3h molecules 10BF3 and 11BF3. Simulations of the spectra were done using n1 rovibrational

Colloquium: Femtosecond Optical Frequency Combs

October 12, 2021
Author(s)
S T. Cundiff, Jun Ye
Recently there has been a remarkable synergy between the technology of precision laser stabilization and modelocked ultrafast lasers. This has resulted in control of the frequency spectrum produced by modelocked lasers, which consists of a regular comb of

Combined Effect of Coherent Z Exchange and the Hyperfine Interaction in Atomic PNC

October 12, 2021
Author(s)
W R. Johnson, M S. Safronova, U I. Safronova
The nuclear spin-dependent parity nonconserving (PNC) interaction arising from a combination of the hyperfine interaction and the coherent, spin-independent, PNC interaction from Z exchange is evaluated using many-body perturbation theory. For the 6s^1/2^

Comment on Phys. Rev. Lett. 95, 017201 (2005)

October 12, 2021
Author(s)
J A. Bland, S J. Steinmuller, T Trypiniotis, William F. Egelhoff Jr.
In their article High Temperature Ferromagnetism in GaAs-Based Heterostructures with Mn ? Doping , the authors A. M. Nazmul et al. report finding remarkably high Curie temperatures in Mn delta doped GaAs structures. They base their assessment on the

Comment on Stability of Small Carbon-Nitride Heterofullerenes

October 12, 2021
Author(s)
G Sun, Rui-Hua Xie, M C. Niklaus
In a recent Letter [1], Schultz et, al, proposed the existence of heterofullerenes C n-xN x (40 less then or equal to} n less then or equal to} 50) based on the pattern of the peaks in the mass spectrum of carbon-nitride nanostructures produced by the arc

Comparative Dielectric Behavior of PBFe 1/2 Ta 1/2 O 3 and NaNbO 3 :Gd Relaxor-Like Crystals

October 12, 2021
Author(s)
I P. Raevski, S A. Prosandeev, U Waghmare, V V. Eremkin, V G. Smotrakov, V A. Shuvaeva
Experimental data obtained for PBFe 1/2Ta 1/20 3 (PFT) and NaNbO 3:Gd (NaNbGd) single crystals show a diffused dielectric permittivity peak that is inherent to relaxor ferroelectrics. However some deviations from the normal relaxor properties were also
