“…X-ray measurements X-ray observation has been commonly used to study DR processes with an electron-beam ion trap [14,[41][42][43][44][45][46][47]. Our present method to obtain relative differential DR cross sections at 90 • is the same as that used in the previous study [48]. In brief, x rays emitted from the intermediate states produced by the DC were detected with a high-purity Ge detector placed at 90 • with respect to the electron-beam propagation direction while scanning the electron-beam energy over the KL 12 L 12 DR resonance region.…”

The magnetic-sublevel population of the autoionization state formed in dielectronic recombination (DR) of highly charged heavy ions has been experimentally investigated by combining two types of measurements with an electron beam ion trap. The two different measurements are the differential x-ray measurement at 90 • with respect to the electron beam and the integral resonance-strength measurement. The alignment parameter, which denotes the magnetic-sublevel population distribution, has been obtained for the autoionization states [1s2s 2 2p 1/2 ] 1 formed in DR of Li-like Pr (atomic number Z = 59) and Ho (Z = 67). This work is a complement to our previous work [Phys. Rev. Lett. 108, 073002 (2012)] on Li-like Au (Z = 79). The experimental results are in reasonable agreement with theoretical predictions, and a strong Z-dependent tendency due to the Breit interaction has been confirmed.

“…Furthermore, QMA-EUR had been demonstrated experimentally [27,28] and also generalized by the Rényi entropy. [29,30] Additionally, some authors have made many efforts to improve the lower bounds in, [31][32][33][34][35][36] and the uncertainty inequality has been expanded to multipartite systems [37,38] and the stronger entropic uncertainty relations for multiple measurements have been reported. [39] Canonically, a quantum system cannot escape from its surrounding environment and inevitably couples with the environmental noises, which will result in decoherence or dissipation effects.…”

Dynamical Measurement's Uncertainty in the Curved Space‐Time

The dynamical characteristics of measurement's uncertainty are investigated under two modes of Dirac field in the Garfinkle-Horowitz-Strominger dilation space-time. It shows that the Hawking effect induced by the thermal field would result in an expansion of the entropic uncertainty with increasing dilation-parameter value, as the systemic quantum coherence reduces, reflecting that the Hawking effect could undermine the systemic coherence. Meanwhile, the intrinsic relationship between the uncertainty and quantum coherence is obtained, and it is revealed that the uncertainty's bound is anti-correlated with the system's quantum coherence. Furthermore, it is illustrated that the systemic mixedness is correlated with the uncertainty to a large extent. Via the information flow theory, various correlations including quantum and classical aspects, which can be used to form a physical explanation on the relationship between the uncertainty and quantum coherence, are also analyzed. Additionally, this investigation is extended to the case of multi-component measurement, and the applications of the entropic uncertainty relation are illustrated on entanglement criterion and quantum channel capacity. Lastly, it is declared that the measurement uncertainty can be quantitatively suppressed through optimal quantum weak measurement. These investigations might pave an avenue to understand the measurement's uncertainty in the curved space-time.

“…DR resonant strengths can be obtained by normalizing the x-ray intensity from DR to that from RR, for which reliable cross section can be calculated because there is no need to include electron correlation. For example, so far such a method was used to obtain DR resonant strengths for Hlike Kr [41], He-like Ti [42], etc.…”
