Engineering Ge profiles in Si/SiGe heterostructures for increased valley splitting

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Lucas E. A. Stehouwer, Merrit P. Losert, Maia Rigot, Davide Degli Esposti, Sara Martí-Sánchez | Summary: Electron spin qubits in Si/SiGe quantum wells are limited by the small and variable energy separation of the conduction band valleys. While sharp quantum well interfaces are pursued to increase the […]

Soliton resolution for the coupled complex short pulse equation

Kavli Affiliate: Ran Wang | First 5 Authors: Nan Liu, Ran Wang, , , | Summary: We address the long-time asymptotics of the solution to the Cauchy problem of ccSP (coupled complex short pulse) equation on the line for decaying initial data that can support solitons. The ccSP system describes ultra-short pulse propagation in optical […]

Spa-VLM: Stealthy Poisoning Attacks on RAG-based VLM

Kavli Affiliate: Jing Wang | First 5 Authors: Lei Yu, Yechao Zhang, Ziqi Zhou, Yang Wu, Wei Wan | Summary: With the rapid development of the Vision-Language Model (VLM), significant progress has been made in Visual Question Answering (VQA) tasks. However, existing VLM often generate inaccurate answers due to a lack of up-to-date knowledge. To […]

Revisiting the Li abundances of Stars with and without Detected Planets from the High Resolution Spectroscopy

Kavli Affiliate: Subo Dong | First 5 Authors: Jinxiao Qin, Hong-Liang Yan, Wenyuan Cui, Jian-Rong Shi, Subo Dong | Summary: Whether the presence of planets affects the lithium (Li) abundance of their host stars is still an open question. To investigate the difference of the Li abundance between planet-host stars (HS) and isolated stars (IS) […]

Exact Quantum Many-Body Scars in 2D Quantum Gauge Models

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Yuan Miao, Linhao Li, Hosho Katsura, Masahito Yamazaki, | Summary: Quantum many-body scars (QMBS) serve as important examples of ergodicity-breaking phenomena in quantum many-body systems. Despite recent extensive studies, exact QMBS are rare in dimensions higher than one. In this paper, we study a two-dimensional quantum $mathbb{Z}_2$ […]

Ultra High Energy Cosmic Rays

Kavli Affiliate: Roger Blandford | First 5 Authors: Noémie Globus, Roger Blandford, , , | Summary: Ultra High Energy Cosmic Rays, UHECR, are charged particles with energies between $sim10^{18},{rm eV}$ and $sim3times10^{20},{rm eV}sim50,{rm J}$. They exhibit fundamental physics at energies inaccessible to terrestrial accelerators, challenge experimental physics and connect strongly to astronomical observations through electromagnetic, […]

Neuroticism Heterogeneity Through Item-Level Associations in Resting-State Functional Connectivity

Kavli Affiliate: Wesley Thompson | Authors: Masaya Misaki, Chun Chieh Fan, Wesley K Thompson, Heekyeong Park, Bohan Xu and Martin M Paulus | Summary: Neuroticism is characterized by emotional instability and increased susceptibility to stress-related disorders. While traditionally treated as a unitary construct, growing evidence suggests that neuroticism is heterogeneous in both its genetic basis […]
