Symmetry classes, many-body zero modes, and supersymmetry in the complex Sachdev-Ye-Kitaev model
Jan Behrends, Benjamin Béri
The complex Sachdev-Ye-Kitaev (cSYK) model is a charge-conserving model of randomly interacting fermions. The interaction term can be chosen such that the model exhibits chiral sym…
Second-Order Bulk-Boundary Correspondence in Rotationally Symmetric Topological Superconductors from Stacked Dirac Hamiltonians
Elis Roberts, Jan Behrends, Benjamin Béri
Two-dimensional second-order topological superconductors host zero-dimensional Majorana bound states at their boundaries. In this work, focusing on rotation-invariant crystalline t…
Supersymmetry in the nonsupersymmetric Sachdev-Ye-Kitaev model
Jan Behrends, Benjamin Béri
Supersymmetry is a powerful concept in quantum many-body physics. It helps to illuminate ground state properties of complex quantum systems and gives relations between correlation…
Anomalous conductance scaling in strained Weyl semimetals
Jan Behrends, Roni Ilan, Jens H. Bardarson
Magnetotransport provides key experimental signatures in Weyl semimetals. The longitudinal magnetoresistance is linked to the chiral anomaly and the transversal magnetoresistance t…
