Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Maria Teresa Mercaldo, Canio Noce, Andrea D. Caviglia, Mario Cuoco, Carmine Ortix | Summary: The Berry curvature (BC) – a quantity encoding the geometric properties of the electronic wavefunctions in a solid – is at the heart of different Hall-like transport phenomena, including the anomalous Hall […]
Kavli Affiliate: Felix Fischer | First 5 Authors: Javier Cembrano, Felix Fischer, Max Klimm, , | Summary: We study mechanisms that select a subset of the vertex set of a directed graph in order to maximize the minimum indegree of any selected vertex, subject to an impartiality constraint that the selection of a particular vertex […]

Kavli Affiliate: Jill Leutgeb | Authors: Markos Athanasiadis, Stefano Masserini, Li Yuan, Dustin Fetterhoff, Jill K Leutgeb, Stefan Leutgeb and Christian Leibold | Summary: Remembering what just happened is a crucial prerequisite to form long-term memories but also for establishing and maintaining working memory. So far there is no general agreement about cortical mechanisms that […]
Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Xingyao Chen, Shuailiang Ge, Jia Liu, Yan Luo | Summary: Ultralight dark photons and axions are well-motivated hypothetical dark matter candidates. Both dark photon dark matter and axion dark matter can resonantly convert into electromagnetic waves in the solar corona when their mass is equal […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Harry T. J. Bevins, Stefan Heimersheim, Irene Abril-Cabezas, Anastasia Fialkov, Eloy de Lera Acedo | Summary: The first billion years of cosmic history remains largely unobserved. We demonstrate, using a novel machine learning technique, how combining upper limits on the spatial fluctuations in the 21-cm signal with […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Harry T. J. Bevins, Stefan Heimersheim, Irene Abril-Cabezas, Anastasia Fialkov, Eloy de Lera Acedo | Summary: Observations of the first billion years of cosmic history are currently limited. We demonstrate, using a novel machine learning technique, the synergy between observations of the sky-averaged 21-cm signal from neutral […]
Kavli Affiliate: Wei Gao | First 5 Authors: Xiaohui Yan, Yue He, Xuncheng Liu, Siqi Jing, Jiajian Guan | Summary: The further development of fast electrochemical devices is hindered by self-discharge. Current strategies for suppressing self-discharge are mainly focused on the extrinsic and general mechanisms including faradaic reactions, charge redistribution, and ohmic leakage. However, the […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianxiang Zhao, Dongsheng Luo, Xiang Zhang, Suhang Wang, | Summary: Uncovering rationales behind predictions of graph neural networks (GNNs) has received increasing attention over recent years. Instance-level GNN explanation aims to discover critical input elements, like nodes or edges, that the target GNN relies upon for making […]
Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Pritom Mozumdar, Geoff C. -F. Chen, Tommaso Treu, Michele Cappellari | Summary: Strong-lensing time delays enable measurement of the Hubble constant ($H_{0}$) independently of other traditional methods. The main limitation to the precision of time-delay cosmography is mass-sheet degeneracy (MSD). Some of the […]
