AMD Versal AI-Engines for fixed latency environments

Posted by klaurent March 14, 2026Chicago

Kavli Affiliate: David W. Miller | Summary:Complex, high-throughput data acquisition and processing systems, such as those used in high-energy physics experiments, are increasingly moving sophisticated pattern recognition and data compression algorithms closer to the sensors themselves. To meet these needs, programmable device manufacturers offer multi-silicon die packages that commonly include dedicated co-processors within the same […]

Prevalent elongated galaxies in the early Universe evidenced by stellar kinematics

Posted by klaurent March 14, 2026Peking

Kavli Affiliate: Yingjie Peng | Summary:The Universe is now extensively populated by discy galaxies with coherent galaxy-wise stellar rotation. This disc prevalence has been deemed a late-time phenomenon because the penetrating cold gaseous streams in the early Universe ($zgtrsim 2$) fuel the star formation in galaxies too intensively to allow for thin disc formation. However, […]

BERTology of Molecular Property Prediction

Posted by klaurent March 13, 2026Chicago

Kavli Affiliate: Thomas Crawford | Summary:Chemical language models (CLMs) have emerged as promising competitors to popular classical machine learning models for molecular property prediction (MPP) tasks. However, an increasing number of studies have reported inconsistent and contradictory results for the performance of CLMs across various MPP benchmark tasks. In this study, we conduct and analyze […]

Primordial non-Gaussianity constraints on dissipative inflation

Posted by klaurent March 13, 2026Cambridge

Kavli Affiliate: E. P. S. Shellard | Summary:Dissipative effects appear in many early-Universe scenarios, yet their universal observational signatures and systematic confrontation with data remain largely unexplored. We employ the Open Effective Field Theory of Inflation (Open EFToI) to consistently incorporate dissipative and stochastic effects while preserving scale invariance. Dissipation enhances specific interaction channels of […]

A low mass and radius neutron star candidate in XTE J1810-189?

Posted by klaurent March 13, 2026March 23, 2026Peking

Kavli Affiliate: Renxin Xu | Summary:Photosphere radius expansion (PRE) bursts provide a crucial tool for constraining the mass and radius of neutron stars. In this study, we analyze time-resolved spectroscopic data from XTE J1810-189 in 2008, which exhibit evidence of a PRE event. We report here the possibility of a small-size and low-mass neutron star […]

Slow spin-lattice relaxation dynamics in YbVO4 revealed by extended thermal impedance spectroscopy from AC susceptibility and AC magnetocaloric measurements

Posted by klaurent March 13, 2026Caltech

Kavli Affiliate: Linda Ye| Summary:Alternating (AC) magnetic fields can induce not only an alternating magnetization in materials, but also an alternating temperature via the magnetocaloric effect. The latter effect is typically neglected when performing AC susceptibility measurements, but consideration of both effects on an equal footing is necessary in order to reliably distinguish between internal […]

Torsional oscillation of carbon nanotubes driven by electron spins

Posted by klaurent March 13, 2026UCAS

Kavli Affiliate: Mamoru Matsuo | Summary:We theoretically investigate the current-induced excitation of torsional vibrations in a suspended carbon nanotube (CNT) quantum dot. By considering a CNT clamped between half-metallic ferromagnetic electrodes with an antiparallel magnetization configuration, we demonstrate that the spin-rotation coupling (SRC) enables the transfer of angular momentum from electron spins to the mechanical […]

Elastoresistivity Signatures of Nematic Fluctuations in Layered Antiferromagnet CoTa3S6

Posted by klaurent March 13, 2026Caltech

Kavli Affiliate: Linda Ye| Summary:Nematic phases that break rotational symmetry are widely observed in quantum materials, and clarifying their origin and relationship with other symmetry-breaking phases remains an important but challenging task. In this work, we investigate nematic fluctuations in CoTa$_3$S$_6$ using elastoresistivity experiments to resolve the nature of the proposed nematic phase intertwined with […]
