    Wideband Cooperative Localization Through Generalized Cross-Correlation by Andreas Fuchs, Lukas Wielandner, Klaus Witrisal

    Published 2024-01-01
    “…The algorithm is embedded within a message-passing framework, enabling the estimation of the joint-posterior probability density function of all the nodes. The paper evaluates the localization performance, using both simulated and real measurements in various challenging scenarios, and compares it with a cooperative localization method that uses additional received signal strength measurements inbetween nodes. …”

    Superconducting phase diagram of finite-layer nickelates Nd n+1Ni n O2n+2 by Andreas Hausoel, Simone Di Cataldo, Motoharu Kitatani, Oleg Janson, Karsten Held

    Published 2025-07-01
    “…Abstract Following the successful prediction of the superconducting phase diagram for infinite-layer nickelates, here we calculate the superconducting T c vs. the number of layers n for finite-layer nickelates using the dynamical vertex approximation. To this end, we start with density functional theory, and include local correlations non-perturbatively by dynamical mean-field theory for n = 2–7. …”
