Ultra-high-resolution spectroscopy of trapped ion ensembles in the Lamb-Dicke regime: demonstration and determination of the proton-electron mass ratio

Optical spectroscopy in the gas phase is one of the key tools for the elucidation of the structure of atoms and molecules and their interaction with external fields. The line resolution is usually limited by a combination of first-order Doppler broadening due to particle thermal motion and of a short transit time through the excitation beam. For trapped particles, suitable laser cooling techniques can lead to strong confinement (Lamb-Dicke regime, LDR) and thus to optical spectroscopy free of these effects. For non-laser coolable ions, this has so far only been achieved when trapping one or two atomic ions, together with a single laser-coolable atomic ion. Here we show that one-photon optical LDR spectroscopy can also be obtained with more easily prepared ensembles of ions, if performed in the mid-infrared spectral range. We demonstrate the method on molecular ions, for which LDR vibrational spectroscopy has not before been achieved. We trap approximately 100 molecular hydrogen ions (HD$^{+}$) within a Coulomb cluster of a few thousand laser-cooled atomic ions and perform laser spectroscopy of the fundamental vibrational transition. To generate the appropriate spectroscopy radiation (5.1 $\mu$m), a metrology-grade, mid-infrared laser source was developed. We obtain fractional vibrational linewidths of $3\times10^{-12}$, $10^{4}$ times smaller than previous best results for one-photon vibrational spectroscopy of molecular ions. Transition frequencies were determined with lowest uncertainties $3.3\times10^{-12}$ fractionally. As an application, we determine the proton-electron mass ratio by matching a precise $ab~initio$ calculation with the measured vibrational frequency. The mass ratio is in agreement with the most precise recent measurements and has a similar uncertainty. The present technique is relatively simple and applicable to a large variety of molecular ions.Comment: This version was submitted to Nature Physics.

Self-Adjointness of Generalized MIC-Kepler System

We have studied the self-adjointness of generalized MIC-Kepler Hamiltonian, obtained from the formally self-adjoint generalized MIC-Kepler Hamiltonian. We have shown that for \tilde l=0, the system admits a 1-parameter family of self-adjoint extensions and for \tilde l \neq 0 but \tilde l <{1/2}, it has also a 1-parameter family of self-adjoint extensions.Comment: 11 pages, Latex, no figur

The Effect of Salinity on Survival, Growth and Immunity Rate of Sea Cucumber (Holothuria Scabra) Juveniles

Sea cucumber is a stenohaline and osmoconforming organism with a low level of tolerance to salinity change. Salinity of the medium is one of the physiological factors that affect the growth and survival of sea cucumber juveniles. This study was aimed at finding out the effect of different salinities on growth, survival and immunity rate of sea cucumber juveniles (Holothuria scabra) and finding the most suitable salinity level for optimal growth, survival and immunity rate of sea cucumber. This study used a laboratory experimental method and completely randomized design with 5 salinity treatments: 24, 29, 34, 39, and 44 ppt with 3 replications. This study used fifteen 30 L-fiber glass tanks. The sea cucumber juvenile were 4.4 ± 0.2 cm in total length and 5.6 ± 0.3 g in body weight. The juvenile densities were 15 individuals/tank, fed with fresh benthos from a culture once a day in the afternoon. Coelomate was taken from the sea cucumber juveniles from each tank and used to find out the immunity rate dan also the for osmolality. The data collected were analyzed using ANOVA that was followed by Tukey's test at 5% level of significance. The results showed that the salinity of the medium has a significant effect (P &lt; 0.05) on the growth, survival rate and immunity rate of sea cucumber juveniles. The 24 - 34 ppt salinity can support survival rate up to 100%, high growth (6.47 – 7.10 g) and immunity rate (27 – 76 x 104 phagocytic cell/mL), while at the 44 ppt salinity has an effect not only on a low survival rate (55.6%), but also on a bad effect on osmolality (303 ± 3.5 mOs-mol kg-1), growth (3.12 ± 0.34 g), and immunity (209 x 104 phagocytic cell/mL)

The brachistochrone problem in open quantum systems

Recently, the quantum brachistochrone problem is discussed in the literature by using non-Hermitian Hamilton operators of different type. Here, it is demonstrated that the passage time is tunable in realistic open quantum systems due to the biorthogonality of the eigenfunctions of the non-Hermitian Hamilton operator. As an example, the numerical results obtained by Bulgakov et al. for the transmission through microwave cavities of different shape are analyzed from the point of view of the brachistochrone problem. The passage time is shortened in the crossover from the weak-coupling to the strong-coupling regime where the resonance states overlap and many branch points (exceptional points) in the complex plane exist. The effect can {\it not} be described in the framework of standard quantum mechanics with Hermitian Hamilton operator and consideration of $S$ matrix poles.Comment: 18 page

Normal mode analysis for scalar fields in BTZ black hole background

We analyze the possibility of inequivalent boundary conditions for a scalar field propagating in the BTZ black hole space-time. We find that for certain ranges of the black hole parameters, the Klein-Gordon operator admits a one-parameter family of self-adjoint extensions. For this range, the BTZ space-time is not quantum mechanically complete. We suggest a physically motivated method for determining the spectra of the Klein-Gordon operator.Comment: 6 pages, no figure, late

CP Violation in \tau ->\nu\pi K_S and D->\pi K_S: The Importance of K_S-K_L Interference

The $B$-factories have measured CP asymmetries in the $\tau\to\pi K_S\nu$ and $D\to K_S\pi$ modes. The $K_S$ state is identified by its decay to two pions at a time that is close to the $K_S$ lifetime. Within the Standard Model and many of its extensions, the asymmetries in these modes come from CP violation in $K^0-\bar{K}^0$ mixing. We emphasize that the interference between the amplitudes of intermediate $K_S$ and $K_L$ is as important as the pure $K_S$ amplitude. Consequently, the measured asymmetries depend on the times over which the relevant decay rates are integrated and on features of the experiment.Comment: 4 pages, 4 figure

Possibility of extracting the weak phase γ\gamma from Λb→ΛD0\Lambda_b \to \Lambda D^0 decays

We explore the possibility of extracting the weak phase $\gamma$ from pure tree decays $\Lambda_b \to \Lambda (D^0, \bar{D^0}, D^0_{CP})$ in a model independent way. The CP violating weak phase $\gamma$ can be determined cleanly, without any hadronic uncertainties, as these decay modes are free from the penguin pollutions. Furthermore, neither tagging nor time dependent studies are required to extract the angle $\gamma$ with these modes.Comment: 12 pages, LaTex, Minor changes in the text, version to appear in Phys. Rev.
