Welcome

Stefan Käser, Hugo U. R. Strand, Nils Wentzell, Antoine Georges, Olivier Parcollet, and Philipp Hansmann We study the superconducting gap function of Sr2RuO4. By solving the linearized Eliashberg equation with a correlated pairing vertex extracted from a dynamical mean-field calculation we identi... Continue

Benckiser Heteroepitaxy offers a new type of control mechanism for the crystal structure, the electronic correlations, and thus the functional propertie... Continue

A many-method study of the Hubbard model demonstrates how the field of computational quantum physics is evolving to be more collaborative. Continue

X. Cao, Y. Lu, P. Hansmann, M. W. Haverkort We present a tree tensor-network impurity solver suited for general multiorbital systems. The network is constructed to efficiently capture the entanglement structure and symmetry of an impurity problem. The solver works directly on the real-time/frequenc... Continue
