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…

Exactly Solvable Models Hosting Altermagnetic Quantum Spin Liquids
João Augusto Sobral, Pietro M. Bonetti, Subrata Mandal +1
We construct spin- and spin- models on the square-octagon and checkerboard lattices that are exactly solvable with Majorana representations. They give rise to spin-liquid…

Fractionalized Altermagnets: from neighboring and altermagnetic spin-liquids to spin-symmetric band splitting
João Augusto Sobral, Subrata Mandal, Mathias S. Scheurer
We study quantum-fluctuation-driven fractionalized phases in the vicinity of altermagnetic order. First, the long-range magnetic orders in the vicinity of collinear altermagnetism…
