Summary: Researchers have created a special two-level system in an ensemble of several hundred atoms and observed oscillations between the ground state and collective Rydberg state. They have also obtained the light shifts of the qubits using interference techniques and derived an effective two-level model that agrees well with their observations.

Summary: We have successfully achieved quantum degeneracy in a mixture of highly magnetic 168Er and nonmagnetic 174Yb through forced evaporation in an all-optical trap. The formation of two Bose-Einstein condensates is confirmed by analyzing the cloud shape and observing inversions of the aspect ratios. These results pave the way for new experiments on magnetic and nonmagnetic impurity physics, as well as the study of quantum chaotic behavior of Feshbach resonances and their dependence on slight variations in reduced masses.

Summary: This study investigates ultracold collisions in a novel mixture of Li-6 and Cr-53 fermionic atoms and discovers more than 50 interspecies Feshbach resonances via loss spectroscopy. By constructing a full coupled-channel model, the scattering properties of Li-6-Cr-53 are unambiguously characterized and predictions are made for other isotopic pairs. The identified Feshbach resonances allow for controlled tuning of elastic s- and p-wave Li-6-Cr-53 interactions. This research highlights the suitability of lithium-chromium mixtures for the experimental exploration of highly correlated fermionic matter and the realization of ultracold polar molecules with dual electric and magnetic dipole moments.

Summary: This study demonstrates the coherent manipulation of circular Rydberg states using the electrostatic coupling between the two valence electrons of strontium and optical pulses. The state of the Rydberg electron can be mapped onto the ionic core, enabling non-destructive detection of circular states and the realization of a hybrid optical-microwave platform for quantum technology.

Summary: We discuss the geometric phase of Wannier-Stark ladders generated by periodically driven clock states in alkaline-earth(-like) atoms. Using a concrete example of 171Yb atoms, we show that the differences in geometric phase between different ladders can be experimentally detected through interference between different nuclear spin states, revealing the inherent topological phase transition. Our study sheds light on the engineering of exotic band structures in Floquet dynamics.

Summary: The study explored the effects of alkali and alkaline earth metals on Fe-catalyzed coal pyrolysis, finding that K, Na, Ca, and Mg enhanced the catalytic effect of Fe catalyst, leading to increased H-2 selectivity and decreased CO2 yield. The presence of Na and K showed stronger catalytic activity compared to Ca and Mg.

Summary: In this paper, a platform for universal quantum computation with long-range entangling gates and quantum error correction is proposed, using a mixture of two ultracold atomic species. The system utilizes localized collective spins and phononic excitations to achieve entanglement. The authors also discuss a finite-dimensional version of the Gottesman-Kitaev-Preskill code for protecting quantum information in the system.

Summary: The influence of alkali metals and alkaline earth metals on coke reactivity and coke microstructure was studied, and high-reactivity metallurgical cokes were produced using the mechanical mixing method. The gasification kinetics of coke samples were further investigated to understand the catalytic mechanism of alkali metals and alkaline earth metals on cokes, providing a basis and guidance for hydrogen-rich blast furnace charge production. The addition of alkali metals or alkaline earth metals significantly increased the chemical reactivity index of cokes. Furthermore, it was observed that the microstructure of cokes changed after the addition, with increased contact area and reduced disorder, leading to increased reactivity.

Summary: The new detection method using magnetization generated at triggered radiative emission of neutrino pairs aims to determine unknown neutrino properties such as the absolute neutrino masses and Majorana/Dirac distinction. By preparing a coherently excited body of trivalent lanthanoid ions in a transparent dielectric crystal, the method effectively rejects QED origin background noise. The generated magnetic field stored in crystals long after pair emission event allows for precise measurement of neutrino parameters.
