DOI: 10.1039/d1cc06996a
Abstract: The asymmetric oxidation of a sulfur-containing nine-membered heterocycle was achieved for the late-stage introduction of chirality to the substituents of π-electron systems. The oxidation of the sulfur atom considerably influenced the phase-transition behaviour and crystallinity… read more here.

DOI: 10.1103/physrevb.96.174435
Abstract: We prove that Nagaoka's theorem, that the ground state of the large-U Hubbard model with exactly one hole is ferromagnetic, holds for any balanced Hamiltonian. We argue that, in itinerant electron systems, a balanced Hamiltonian,… read more here.
