Coherent beam combination is one promising way to overcome the power limit of one single laser. In this paper, we use a Multi-Plane Light Converter to combine coherently 12 fibers at 1.03 µm with a phase locking setup. The overall loss measurement gives a combination efficiency in the fundamental Hermite-Gaussian mode as high as 70%. We demonstrate for the first time the beam steering capability of the system.

Article Synopsis
  • Efficient readout of information is crucial for quantum simulation, yet standard measurements typically focus on just one observable at a time.
  • This research introduces an atomic beam splitter for controlled outcoupling, allowing simultaneous measurement of both number imbalance and relative phase in two coupled 1D Bose gases, acting as a simulator for sine-Gordon field theory.
  • The method demonstrates quantum limitations through number squeezing, tracks Josephson oscillation dynamics, and permits atom extraction while preserving coherent dynamics, paving the way for studying quantum properties and multitime correlation functions in larger systems.

Charge transport in materials has an impact on a wide range of devices based on semiconductor, battery, or superconductor technology. Charge transport in sliding charge density waves (CDW) differs from all others in that the atomic lattice is directly involved in the transport process. To obtain an overall picture of the structural changes associated to the collective transport, the large coherent x-ray beam generated by an x-ray free-electron laser (XFEL) source was used.

Designing Hybrid Plasmonic Superlattices with Spatially Confined Responsive Heterostructural Units.

Nano Lett

January 2025

State Key Laboratory of Solidification Processing, Center of Advanced Lubrication and Seal Materials, School of Materials Science and Engineering, Northwestern Polytechnical University, Xi'an 710072, P.R. China.

Plasmonic superlattices enable the precise manipulation of electromagnetic fields at the nanoscale. However, the optical properties of static lattices are dictated by their geometry and cannot be reconfigured. Here, we present a surface-interface engineered plasmonic superlattice with confined polyelectrolyte-functionalized metal-organic framework (MOF) hybrid layers to tune plasmon resonance for ultrafast chemical sensing.

Malignant Transformation of a Choroidal Nevus.

Cureus

December 2024

Department of Ophthalmology, Xi'an No. 3 Hospital, the Affiliated Hospital of Northwest University, Xi'an, CHN.

Choroidal nevus is the most common intraocular tumor, and most cases are benign and have no symptoms. However, choroidal nevus carries a low risk for transformation into melanoma, which is a highly aggressive and deadly cancer. In this case report, we present a male patient with blurred vision in his left eye for six months.

Magic-NOVEL: Suppressing electron-electron coupling effects in pulsed DNP.

J Chem Phys

January 2025

Center for Quantum and Topological Systems, New York University Abu Dhabi, P.O. Box 129188, Abu Dhabi, United Arab Emirates.

Pulsed dynamic nuclear polarization (DNP) enhances the nuclear magnetic resonance sensitivity by coherently transferring electron spin polarization to dipolar coupled nuclear spins. Recently, many new pulsed DNP techniques such as NOVEL, TOP, XiX, TPPM, and BEAM have been introduced. Despite significant progress, numerous challenges remain unsolved.
