Article Synopsis
  • The text discusses a new method to analyze how electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS) affect laser spectroscopy in a four-level microwave-dressed Rydberg system.
  • It highlights that when a microwave field is introduced and its intensity adjusted, the behavior of transparency windows changes, with EIT being dominant when the microwave field is off and transitioning to ATS as it is increased.
  • This four-level approach offers deeper insights into quantum interference in atomic systems, with implications for improved sensitivity and applications in quantum processing and communication.

By effectively controlling the dipole-dipole interaction, we investigate the characteristics of the ground state of bright solitons in a spin-orbit coupled dipolar Bose-Einstein condensate. The dipolar atoms are trapped within a double-lattice which consists of a linear and a nonlinear lattice. We derive the motion equations of the different spin components, taking the controlling mechanisms of the dipole-dipole interaction into account.

Article Synopsis
  • The study explores a method to create optical soliton molecules (SMs) that are two bound solitons with a π-phase difference and how they scatter when encountering a specific type of potential called parity-time (PT) symmetric.
  • To stabilize these SMs, researchers apply a magnetic field that creates a harmonic trap to counteract the repulsive forces between the solitons caused by their phase difference.
  • The scattering behavior of these SMs is significantly influenced by the characteristics of the PT-symmetric potential and the speed at which the SMs approach it, highlighting their potential use in optical information processing and transmission.

Qualitative and quantitative detection methods based on near-infrared spectroscopy (NIRs) have been proposed in the process analysis of traditional Chinese medicine in recent years. In this study, rapid monitoring methods were developed for quality control of concentration process of lanqin oral solution (LOS). Partial least squares regression (PLSR) method was adopted to construct quantitative models for epigoitrin, geniposide, baicalin, berberine hydrochloride and density.
