Lamb-dips and Lamb-peaks in the saturation spectrum of HD [PDF]

Optics Letters, 2019
The saturation spectrum of the R(1) transition in the (2-0) band in HD is found to exhibit a composite line shape, involving a Lamb-dip and a Lamb-peak. We propose an explanation for such behavior based on the effects of cross-over resonances in the hyperfine substructure, which is made quantitative in a density-matrix calculation.

Lamb shift of non-degenerate energy level systems placed between two infinite parallel conducting plates

, 2012
The issue of the observability of the Lamb shift in systems with non-degenerate energy levels is put to question. To this end, we compute the Lamb shift of such systems in the electromagnetic environment provided by two infinite parallel conducting ...

Laser Cooling of two trapped ions: Sideband cooling beyond the Lamb-Dicke limit [PDF]

, 1998
We study laser cooling of two ions that are trapped in a harmonic potential and interact by Coulomb repulsion. Sideband cooling in the Lamb-Dicke regime is shown to work analogously to sideband cooling of a single ion.

Immunostimulatory activity of inactivated environmental Bacillus isolates and their endospores

Scientific Reports
The spore-forming capacity of Bacillus spp. enables environmental persistence and stable product formulations, yet the interactions of environmental Bacillus spores and vegetative cells with the human immune system are not fully understood.

Motional frequency shifts of trapped ions in the Lamb-Dicke regime

, 2007
First order Doppler effects are usually ignored in laser driven trapped ions when the recoil frequency is much smaller than the trapping frequency (Lamb-Dicke regime).

The stressing effect of shearing in mid-pregnancy of Zandi ewes on live weight and body sizes of twin lambs at the time of birth

Journal of the Indonesian Tropical Animal Agriculture, 2023
This research investigated the effect of stress of mid-pregnancy shorn Zandi ewes on the live birth weight and body sizes of twin lambs. A total of 96 Zandi ewes, confirmed pregnant with twins, were randomly allocated on day 80 of pregnancy into 4 groups,

Lamb shift in muonic helium ion [PDF]

, 2006
The Lamb shift (2P_{1/2}-2S_{1/2}) in the muonic helium ion (mu ^4_2He)^+ is calculated with the account of contributions of orders alpha^3, alpha^4, alpha^5 and alpha^6.

Lamb Shift for static atoms outside a Schwarzschild black hole

, 2010
We study, by separately calculating the contributions of vacuum fluctuations and radiation reaction to the atomic energy level shift, the Lamb shift of a static two-level atom interacting with real massless scalar fields in the Boulware, Unruh and Hartle-
