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…
Anomalous impurity-induced charge modulations in black phosphorus
Byeongin Lee, Junho Bang, Sayan Banerjee +6
We observe anomalous charge modulations induced by ionized indium impurities on the surface of the semiconductor black phosphorus by scanning tunneling microscopy (STM). When the i…
Physics-informed Transformers for Electronic Quantum States
João Augusto Sobral, Michael Perle, Mathias S. Scheurer
Neural-network-based variational quantum states in general, and more recently autoregressive models in particular, have proven to be powerful tools to describe complex many-body wa…
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…
