Quantum Path Control in High-Order Harmonic Generation via Squeezed Lights

Posted by klaurent Berkeley, This Week: Nanoscience

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Feng Wang, , , | Summary: High-order harmonic generation (HHG), a robust tabletop source for producing attosecond pulses, has been extensively utilized in attosecond metrology. Traditionally, HHG driven by classical laser fields involves two typical quantum paths (short and long quantum paths) contributing to harmonic […]

OverLayBench: A Benchmark for Layout-to-Image Generation with Dense Overlaps

Posted by klaurent Berkeley, This Week: Nanoscience

Kavli Affiliate: Xiang Zhang | First 5 Authors: Bingnan Li, Bingnan Li, , , | Summary: Despite steady progress in layout-to-image generation, current methods still struggle with layouts containing significant overlap between bounding boxes. We identify two primary challenges: (1) large overlapping regions and (2) overlapping instances with minimal semantic distinction. Through both qualitative examples […]

Observation of synchronization between two quantum van der Pol oscillators in trapped ions

Posted by klaurent Berkeley, This Week: Nanoscience

Kavli Affiliate: Joel E. Moore | First 5 Authors: Jiarui Liu, Jiarui Liu, , , | Summary: Synchronization is a hallmark of nonlinear dynamics. It drives self-organized behavior across systems ranging from astronomy to chemistry. Among the simplest systems, the van der Pol oscillator captures the essence of limit-cycle behavior and forms the basis for […]

Audiobook-CC: Controllable Long-context Speech Generation for Multicast Audiobook

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Min Liu, Min Liu, , , | Summary: Existing text-to-speech systems predominantly focus on single-sentence synthesis and lack adequate contextual modeling as well as fine-grained performance control capabilities for generating coherent multicast audiobooks. To address these limitations, we propose a context-aware and emotion controllable speech synthesis framework […]

A zero-dead-time strontium lattice clock with a stability at $10^-19$ level

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiao-Yong Liu, Xiao-Yong Liu, , , | Summary: Optical atomic clocks play a crucial role in fundamental physics, relativistic geodesy, and the future redefinition of the SI second. Standard operation relies on cyclic interrogation sequences, which alternate between atomic interrogation and dead time used for state preparation […]

Terahertz electrodynamics in a zero-field Wigner crystal

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Su-Di Chen, Su-Di Chen, , , | Summary: In clean two-dimensional (2D) systems, electrons are expected to self-organize into a regular lattice, a Wigner crystal, when their mutual Coulomb repulsion overwhelms kinetic energy. Understanding the Wigner crystal at zero magnetic field is a long-sought goal in physics, […]
