Hai-Yang Zhang and Ning Xu shed some light on magnetic excitations in iron pnictides
unconventional superconductivity
How do electrons differ from holes in unconventional superconductors?
Marcin Wysokiński and Jan Kaczmarczyk theoretically investigate the electron–hole asymmetry of d-wave superconductivity driven by the non-local effects of correlations in the generalized single-band Hubbard model.
