When DFT or CC fails, then multireference methods are often the methods of choice in chemistry. In these methods one uses the “diagonalize-then-perturb” strategy, whereby the Hamiltonian is first ...

Researchers have discovered a new phenomenon in which a structural phase transition occurs simultaneously with magnetic ordering in Co₁₋ₓFeₓV₂O₄. The Jahn–Teller effect, proposed by Jahn and Teller in ...

The experimental observation of this Haldane state by Lee et al., using neutron scattering experiments, is a telltale sign of the effectively one-dimensional world that the cold electrons are living ...
