Spin excitations in olympicene-based antiferromagnetic spin-1/2 Heisenberg chains

New publication in Nature Materials, an international team of researchers has developed groundbreaking artificial chains of the iconic ‘olympicene’ molecules to realize the antiferromagnetic (AF) spin-½ Heisenberg model, a flagship quantum spin model that has been the cornerstone of quantum magnetism, since the seminal work of Bethe, for almost a century now. This study makes nanographenes (NGs) an ideal platform for realizing and studying highly entangled quantum spin systems, with potential applications in insulator-based AF spintronics. more

In a recent study published in Nature, an international team of researchers has developed a groundbreaking two-dimensional conducting polymer—polyaniline (2DPANI)—that exhibits exceptional electrical conductivity and metallic charge transport behavior. Unlike conventional conducting polymers, which show strong conduction along polymer chains but suffer from poor interchain/interlayer conductivity, 2DPANI overcomes these limitations with its unique crystal structure, enabling efficient electron flow both within and across its layers. more
