Theory of Angle Resolved Photoemission Spectroscopy of Altermagnetic Mott Insulators
Lorenzo Lanzini, Purnendu Das, Michael Knap
Altermagnetism has emerged as an unconventional form of collinear magnetism with spatial rotational symmetries, that give rise to strongly spin-split bands despite of an underlying…

Inverse Superconductor-Insulator Transition in Weakly Monitored Josephson Junction Arrays
Purnendu Das, Sumilan Banerjee
Control and manipulation of quantum states by measurements and bath engineering in open quantum systems have emerged as new paradigms in many-body physics. Here, taking a prototypi…

Realizing Altermagnetism in Fermi-Hubbard Models with Ultracold Atoms
Purnendu Das, Valentin Leeb, Johannes Knolle +1
Altermagnetism represents a type of collinear magnetism, that is in some aspects distinct from ferromagnetism and from conventional antiferromagnetism. In contrast to the latter, s…
