Anomalous Shiba states in topological iron-based superconductors

arXiv 2022年

作者： Ghazaryan, Areg Kirmani, Ammar Fernandes, Rafael M. Ghaemi, Pouyan Institute of Science and Technology Austria Am Campus 1 Klosterneuberg3400 Austria Physics Department City College of the City University of New York NY10031 United States School of Physics and Astronomy University of Minnesota MinneapolisMN55455 United States Physics Program Graduate Center of City University of New York NY10031 United States

We demonstrate the formation of robust zero energy modes close to magnetic impurities in the iron-based superconductor FeSe1−xTex. We find that the Zeeman field generated by the impurity favors a spin-triplet inter-or... 详细信息

We examine feasibility of accurate estimations of universal critical data using tensor renormalization group (TRG) algorithm introduced by Levin and Nave1. Specifically, we compute critical exponents γ, γ/ν, δ, η... 详细信息

We examine two conditions that can be used to detect bipartite entanglement, and show that they can be used to provide lower bounds on the negativity of states. We begin with two-qubit states, and then show how what w... 详细信息
