DOI: 10.1073/pnas.2204765119
Abstract: Significance Essential biomolecules, like amino acids and sugars, are chiral; they exist in mirror symmetrical pairs named enantiomers. However, modern life selectively uses only one of the enantiomers. The origin of this chiral symmetry breaking… read more here.

DOI: 10.1103/physrevb.104.014504
Abstract: A number of recent experiments indicate that the iron-chalcogenide FeSe provides the long-sought possibility to study bulk superconductivity in the cross-over regime between the weakly coupled Bardeen--Cooper--Schrieffer (BCS) pairing and the strongly coupled Bose--Einstein condensation… read more here.
