Interplay of energy and charge transfer in WSe2/CrSBr heterostructures

Posted by klaurent Delft

Kavli Affiliate: Herre Van Der Zant | Summary:Van der Waals heterostructures (vdWHs) composed of transition-metal dichalcogenides (TMDs) and layered magnetic semiconductors offer great opportunities to manipulate exciton and valley properties of TMDs. Here, we present magneto-photoluminescence (PL) studies in a WSe2 monolayer (ML) on a CrSBr crystal, an anisotropic layered antiferromagnetic semiconductor. Our results reveal […]

First-principles response simulation of wide-gap CdTe-DSDs for the FOXSI solar sounding rocket experiment

Posted by klaurent Tokyo

Kavli Affiliate: Tadayuki Takahashi | Summary:We have developed a wide-gap CdTe double-sided strip detector (CdTe-DSD) for the fourth and fifth flights of the Focusing Optics X-ray Solar Imager sounding rocket experiment (FOXSI-4/FOXSI-5). This detector features a 30 um strip width and a variable gap width from 30 um to 70 um, enabling position resolution finer […]

Signal processing and data acquisition system for the BTO detectors onboard COSI

Posted by klaurent Tokyo

Kavli Affiliate: Tadayuki Takahashi | Summary:The energy range from a few hundred keV to a few MeV includes important probes such as nuclear gamma-rays and the 511 keV annihilation line. However, compared to X-rays and GeV/TeV gamma-rays, this range suffers from lower sensitivity by orders of magnitude. The upcoming NASA SMEX satellite mission Compton Spectrometer […]

The Resurgence of GCG Adversarial Attacks on Large Language Models

Posted by klaurent Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Yuting Tan, Yuting Tan, , , | Summary: Gradient-based adversarial prompting, such as the Greedy Coordinate Gradient (GCG) algorithm, has emerged as a powerful method for jailbreaking large language models (LLMs). In this paper, we present a systematic appraisal of GCG and its annealing-augmented variant, T-GCG, across […]

Quasar Radiative Feedback May Suppress Galaxy Growth on Intergalactic Scales at $z = 6.3$

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino| First 5 Authors: Yongda Zhu, Yongda Zhu, , , | Summary:We present observational evidence that intense ionizing radiation from a luminous quasar suppresses nebular emission in nearby galaxies on intergalactic scales at $z=6.3$. Using JWST/NIRCam grism spectroscopy from the SAPPHIRES and EIGER programs, we identify a moderate but statistically significant decline […]

Computationally Tractable Offline Quantum Experimental Design for Nuclear Spin Detection

Posted by klaurent Delft

Kavli Affiliate: Tim H. Taminiau| First 5 Authors: B. Varona-Uriarte, B. Varona-Uriarte, , , | Summary:The characterization of nuclear spin environments in solid-state devices plays an important role in advancing quantum technologies, yet traditional methods often demand long measurement times. To address this challenge, we extend our recently developed deep-learning-based SALI model (Signal-to-image ArtificiaL Intelligence) […]
