Probing the real-space density of spin-entangled electrons
Federico Pisani, Leonie Spitz, Libor VojáÄek +12
On the textbook example of an isolated antiferromagnetic Heisenberg dimer, we demonstrate that the magnetic form factor and the magnetic electron density distribution can be extrac…

Confined and deconfined spinon excitations in the rectangular-lattice quantum antiferromagnet
N. E. Shaik, E. Fogh, B. Dalla Piazza +3
Fractionalization remains one of the most fascinating manifestations of strong interactions in quantum many-body systems. In quantum magnetism, the existence of spinons -- collecti…
