Robust Beamforming Design for Secure Near-Field ISAC Systems

Posted by klaurent July 17, 2025July 28, 2025Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Ziqiang CHen, Ziqiang CHen, , , | Summary: This letter investigates the robust beamforming design for a near-field secure integrated sensing and communication (ISAC) system with multiple communication users (CUs) and targets, as well as multiple eavesdroppers. Taking into account the channel uncertainty constraints, we maximize the […]

The Physical Origin and Time Lag of Multi-Frequency Flares from SgrA*

Posted by klaurent July 17, 2025July 28, 2025Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Hong-Xuan Jiang, Hong-Xuan Jiang, , , | Summary: Sagittarius~A$^*$, the supermassive black hole at the center of our galaxy, exhibits flares across various wavelengths, yet their origins remain elusive. We performed 3D two-temperature General Relativistic Magnetohydrodynamic (GRMHD) simulations of magnetized accretion flows initialized from multi-loop magnetic field […]

Extreme Thermal Insulation in Nano-Bubble Wrap Materials

Posted by klaurent July 16, 2025Berkeley

Kavli Affiliate: Archana Raja| Summary:Achieving ultra-low thermal conductivity under ambient conditions is a fundamental challenge constrained by classical heat transport limits and material design trade-offs. Here, we introduce a new class of nano-bubble wrap architectures that achieve exceptionally low thermal conductivity by integrating nanoscale gas confinement with atomically thin, weakly coupled van der Waals solids.
