On the trivalent junction of three non-tachyonic heterotic string theories

Posted by klaurent Tokyo

Kavli Affiliate: Yuji Tachikawa | Summary:Recently, Altavista, Anastasi, Angius and Uranga discussed a method to construct junctions and bouquets of different perturbative string theories. Following this analysis, we here argue that three non-tachyonic ten-dimensional heterotic string theories can be joined together at a nine-dimensional junction. This is done by creating a two-dimensional non-conformal $mathcalN=(0,1)$ supersymmetric […]

$AutoDrivetext-P^3$: Unified Chain of Perception-Prediction-Planning Thought via Reinforcement Fine-Tuning

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:Vision-language models (VLMs) are increasingly being adopted for end-to-end autonomous driving systems due to their exceptional performance in handling long-tail scenarios. However, current VLM-based approaches suffer from two major limitations: 1) Some VLMs directly output planning results without chain-of-thought (CoT) reasoning, bypassing crucial perception and prediction stages which creates a significant […]

Octree-based Learned Point Cloud Geometry Compression: A Lossy Perspective

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao| Summary:Octree-based context learning has recently become a leading method in point cloud compression. However, its potential on lossy compression remains undiscovered. The traditional lossy compression paradigm using lossless octree representation with quantization step adjustment may result in severe distortions due to massive missing points in quantization. Therefore, we analyze data characteristics […]

Ferromagnetic resonance modulation in topological materials with bulk–boundary coexistence

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | Summary:We extend ferromagnetic resonance (FMR) modulation theory to describe systems in which bulk and boundary states of topological materials coexist, with both appearing at the same energy. As an application of the formulation, we investigate the enhancement of the Gilbert damping constant on the $(110)$ surface of a $d$-wave superconductor […]

Catching the Nebular Needle in a Polluted Haystack: Line-emission Signatures from Population III-forming Pockets around Massive Galaxies at the End of Reionization

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | Summary:Finding the first generation of (Population III or Pop III) stars is one of the most ambitious and exciting challenges of astrophysics. JWST opened concrete prospects for their detection during the Epoch of Reionization (EoR), where increasing evidence suggests that residual Pop III formation may persist, even within pristine pockets […]

Partial parabolic amplification in rare-earth-doped optical fiber

Posted by klaurent Cornell

Kavli Affiliate: Frank Wise | Summary:Nonlinear amplification is a powerful technique for generating ultrashort laser pulses with high peak power in fiber systems. However, the diversity of nonlinear amplification approaches and their inherent complexities present significant challenges to achieving a unified understanding and further scaling of peak power and pulse energy while preserving ultrashort durations. […]
