Coherent phonon motions and ordered vacancy compound mediated quantum path interference in Cu-poor CuIn$_x$Ga$_(1-x)$Se$_2$ (CIGS) with attosecond transient absorption

Posted by klaurent Berkeley

Kavli Affiliate: Peidong Yang | First 5 Authors: Hugo Laurell, Hugo Laurell, , , | Summary: In this study, coherent phonon motion is observed in bandgap excited CuIn$_x$Ga$_(1-x)$Se$_2$ (CIGS) utilizing extreme ultraviolet (XUV) attosecond transient absorption spectroscopy across the Se M$_4,5$ absorption edge. Two frequencies of coherent phonon motion are resolved, a low frequency mode […]

Fentanyl reinforcement history has sex-specific effects on multi-step decision-making

Posted by dbos Hopkins

Kavli Affiliate: Patricia Janak | Authors: Eric Garr, Yifeng Cheng, Andy Dong and Patricia H. Janak | Summary: It is commonly thought that drug addiction involves a transition to habitual control of action, where the choice to consume drugs becomes automatized and reflects a failure to deliberate over possible negative outcomes. Determining whether the pursuit […]

Topological Freeze-out by Semi-Annihilation

Posted by dbos Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Joe Davighi, Serah Moldovsky, Hitoshi Murayama, Christiane Scherb, Nudzeim Selimovic | Summary: We point out that a QCD-like dark sector can be coupled to the Standard Model by gauging the topological Skyrme current, which measures the dark baryon number in the infrared, to give a technically natural […]

Backward Responsibility in Transition Systems Beyond Safety

Posted by dbos Cornell

Kavli Affiliate: Johannes Lehmann | First 5 Authors: Christel Baier, Rio Klatt, Sascha Klüppelholz, Johannes Lehmann, | Summary: As the complexity of software systems rises, methods for explaining their behaviour are becoming ever-more important. When a system fails, it is critical to determine which of its components are responsible for this failure. Within the verification […]

Structured Labeling Enables Faster Vision-Language Models for End-to-End Autonomous Driving

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Hao Jiang, Chuan Hu, Yukang Shi, Yuan He, Ke Wang | Summary: Vision-Language Models (VLMs) offer a promising approach to end-to-end autonomous driving due to their human-like reasoning capabilities. However, troublesome gaps remains between current VLMs and real-world autonomous driving applications. One major limitation is that existing […]

Buried unstrained Ge channels: a lattice-matched platform for quantum technology

Posted by dbos Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Davide Costa, Karina Hudson, Patrick Del Vecchio, Lucas E. A. Stehouwer, Alberto Tosato | Summary: Ge and Si strained quantum wells have enabled the most advanced spin-qubit quantum processors, but they are deposited on defective, metamorphic SiGe substrates, which may impact device performance and scaling. Here we […]
