Intervalley coherence and flavor polarization in three-valley moiré systems
Jeyong Park, Laura Classen, Mathias S. Scheurer
We investigate interaction-induced symmetry breaking in moiré superlattices created by twisting two identical materials where the electronic low-energy degrees of freedom reside i…
Probing pairing symmetries through quasiparticle interference in chiral Bloch bands
Sayan Banerjee, Subrata Mandal, Peter P. Orth +1
Recent experiments in van der Waals multi-layer systems have demonstrated that superconductivity can emerge from symmetry-reduced, chiral normal states. We here provide a theory fo…
Noise spectroscopy of insulating and itinerant altermagnets
Lucas V. Pupim, Mathias S. Scheurer
One of the central goals in the emergent field of altermagnetism is the unambiguous experimental identification and characterization of altermagnetic order across a variety of comp…
Hatsugai-Kohmoto-like Models for Altermagnets and Odd-Parity Magnets
Konstantin Rickelt, Denis Sedov, Mathias S. Scheurer
We introduce a generalized Hatsugai-Kohmoto multi-orbital model and study its phase diagram and physical properties in the additional presence of perturbations that lift any extens…
Tuning correlated states of twisted mono-bilayer graphene with proximity-induced spin-orbit coupling
Jeyong Park, Mingdi Luo, Louk Rademaker +3
We study the correlated ground states of twisted mono-bilayer graphene with and without proximity-induced spin-orbit coupling (SOC) from a transition-metal dichalcogenide layer pla…
Altermagnetic Superconducting Diode Effect in MnPt/Nb Heterostructures
Saurav Sachin, Mathias S. Scheurer, Constantin Schrade +1
Compensated magnetic orders that can split the spin-degeneracy of electronic bands have become a very active field of research. As opposed to spin-orbit coupling, the splitting res…
