Exact solution of the topological symplectic Kondo problem
Elio J. König, Alexei M. Tsvelik
The Kondo effect is an archetypical phenomenon in the physics of strongly correlated electron systems. Recent attention has focused on the application of Kondo physics to quantum i…
Emergent moments in a Hund's impurity
Victor Drouin-Touchette, Elio J. König, Yashar Komijani +1
Motivated by the relevance of Hund's coupling in the context of multiorbital superconductors, we revisit the problem of a multiorbital Kondo impurity with Hund's interaction. Using…
Tunneling spectroscopy of quantum spin liquids
Elio J. König, Mallika T. Randeria, Berthold Jäck
We examine the spectroscopic signatures of tunneling through a Kitaev quantum spin liquid (QSL) barrier in a number of experimentally relevant geometries. We combine contributions…
Spin magnetometry as a probe of stripe superconductivity in twisted bilayer graphene
E. J. König, Piers Coleman, A. M. Tsvelik
The discovery of alternating superconducting and insulating ground-states in magic angle graphene has suggested an intriguing analogy with cuprate high- materials. Here we arg…
The Triplet Resonating Valence Bond State and Superconductivity in Hund's Metals
Piers Coleman, Yashar Komijani, Elio J. König
A central idea in strongly correlated systems is that doping a Mott insulator leads to a superconductor by transforming the resonating valence bonds (RVBs) into spin-singlet Cooper…
Magic-Angle Semimetals with Chiral Symmetry
Yang-Zhi Chou, Yixing Fu, Justin H. Wilson +2
We construct and solve a two-dimensional, chirally symmetric model of Dirac cones subjected to a quasiperiodic modulation. In real space, this is realized with a quasiperiodic hopp…
