Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Helene Spring, Viktor Könye, Fabian A. Gerritsma, Ion Cosma Fulga, Anton R. Akhmerov | Summary: Disorder can localize the eigenstates of one-dimensional non-Hermitian systems, leading to an Anderson transition with a critical exponent of 1. We show that, due to the lack of energy conservation, the […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, , , , | Summary: We consider the problem of inferring the underlying graph topology from smooth graph signals in a novel but practical scenario where data are located in distributed clients and are privacy-sensitive. The main difficulty of this task lies in how to […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Qiao Wang, , , | Summary: We consider the problem of inferring graph topology from smooth graph signals in a novel but practical scenario where data are located in distributed clients and prohibited from leaving local clients due to factors such as privacy concerns. The […]

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Bolei Deng, Jordan R. Raney, Katia Bertoldi, Vincent Tournat, | Summary: Flexible mechanical metamaterials are compliant structures engineered to achieve unique properties via the large deformation of their components. While their static character has been studied extensively, the study of their dynamic properties is still at an […]

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: 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 […]
