Summary: The researchers demonstrated microwave-assisted coherent control of ultracold polar molecules in a ladder-type configuration of rotational states. By varying the Rabi frequency of the control field, they observed broadening of the probe spectrum splitting and a shift of the central frequency. Applying Akaike's information criterion (AIC), they concluded that the coherent spectral response appears in the crossover regime between electromagnetically induced transparency and Aulter-Townes splitting.

Summary: The study aims to obtain soliton-type solutions for the conformable time-fractional complex Ginzburg-Landau equation with Kerr law nonlinearity. Generalized and modified Kudryashov methods are applied to the given model. By utilizing a suitable wave transform, the equation is converted into an ordinary differential equation. The proposed methods are then used to solve the reduced equation. The results demonstrate the effectiveness and power of both methods. Furthermore, 3D and contour plots are provided for visualization. This research contributes significantly to scientific and physical applications, and the results are novel in the literature.

Summary: In this paper, we present a method using acousto-optic deflectors to trap ultracold cesium atoms in one-dimensional atomic ensembles. We study the time interval between optical tweezer pulses and its effect on the number of atoms trapped in a single trap. We also demonstrate evaporative cooling of atoms and the preparation of atomic-ensemble arrays using multiple optical tweezers.

Summary: In order to expand the material options for outer space and small spacecraft, researchers studied ladder polyphenylsilsesquioxanes with varying molar weights and Nb-siloxane composites based on them. The polymer films were tested in an oxygen plasma flow and showed extremely low erosion coefficients. The ladder polyphenylsilsesquioxanes demonstrated their suitability for protective and optically transparent coatings for small spacecraft that are resistant to the erosive effects of incoming oxygen plasma.

Summary: The study explores the optimization of optical quantum memories based on resonant and near-resonant interaction with ensembles of A-type level systems, with the condition that the temporal envelope of all optical fields must be Gaussian for experimental simplicity. The optimization demonstrated a path to saturate the storage efficiency bound independent of protocol, and revealed a continuous transformation between three physically distinct resonant quantum memory protocols through optimal Gaussian control field parameters. The study compares this Gaussian optimization scheme with standard shape-based optimization.

Summary: In this study, it is shown that light can self-stop in a fully homogeneous medium through self-interaction mediated by resonant nonlinearity. An intense few-cycle pulse entering the medium can reshape itself into a strongly coupled light-matter bundle, where energy is periodically transferred between light and the medium on a single-cycle scale. The oscillating structure can decelerate, change its propagation direction, and even fully stop, depending on the internal degrees of freedom.

Summary: This article investigates the sensitivity of Lambda-type quantum memory to experimental fluctuations and drift. The authors use a variance-based approach to focus on the effects of fluctuations and drift on memory efficiency. They find that the parameters that a quantum memory is most sensitive to depend on the quantum memory protocol being employed. The results have practical ramifications for quantum memory experiments.

Summary: Based on the current growth technology of quantum dot in the experiment, different energy level configurations can be formed in InAs/GaAs quantum dots. The linear and nonlinear properties of these energy level configurations are studied using semiclassical theory combined with multiple scale method. Transparent windows in electromagnetic induction can be formed among different energy level configurations, and the width of the transparent window increases with the strength of the control pulse. Optical solitons can be formed and stored in certain energy level configurations, but not in others due to weak nonlinear effects. The fidelity of the storage and retrieval of optical solitons is higher than that of linear optical pulse and strongly nonlinear optical pulse.

Summary: In this paper, the solutions of the KPI equation are constructed using the theory of four operators and in the form of Grammian. The 1-lump, 3-lump, 6-lump, and high-order lump wave solutions are obtained using a non-homogeneous polynomial. All the lumps undergo anomalous scattering with time. The high-order rogue wave solutions describe the exchange of multiple-lump molecules among resonant solitons, indicating a new nonlinear phenomenon of multiple molecular states. The interaction solutions of N-resonant solitons radiating N-lump molecules are proposed and the anomalous interactions among the lumps and between the lumps and resonant solitons are examined in detail. The obtained solutions are illustrated graphically and have applications in various fields of nonlinear physics.

Summary: In this study, exact traveling wave solutions of coupled nonlinear Hirota equation (CNHE) were obtained using the generalized (G'/G)-expansion method. The obtained solutions include hyperbolic, trigonometric, and exponential solutions. The analytical results were confirmed through symbolic calculation using Mathematica 11.2. The solutions were illustrated through 3D graphs and 2D plots. The present method has been successfully used to obtain exact traveling wave solutions for various nonlinear partial differential equations.

Summary: In this study, steady-state phases of a one-dimensional array of Rydberg atoms coupled by a microwave field were investigated. The interplay among the microwave coupling, van der Waals interaction, and single-body and collective decay between Rydberg states was examined. Different phases, including uniform, antiferromagnetic, oscillatory, bistable, and multistable phases, were observed. Numerical simulations and linear stability analysis were performed to investigate the critical point and scaling of the phase transition with the atom number.

A technique to precisely determine the exceptional point location of the partial PT symmetry breaking is developed.
