Field-resilient supercurrent diode in a multiferroic Josephson junction - Nature CommunicationsThe authors demonstrate a zero-field supercurrent diode effect in NbSe2/NiI2/NbSe2 vertical Josephson junctions, where NiI2 is a two-dimensional multiferroic material. The diode efficiency is even as a function of field, making the device “resilient" to stray fields from nearby circuit components.

Emergent ferromagnetism with superconductivity in Fe(Te,Se) van der Waals Josephson junctions - Nature CommunicationsThe authors study Josephson junctions where the superconductors are Fe(Te,Se) flakes and the weak link is just a 0.36 nm van-der-Waals gap between the two stacked flakes. They report global device-level transport signatures of interfacial ferromagnetism.

It was predicted that in the regime of strong electron-phonon interactions, electrons and phonons can form a coupled non-equilibrium state, characterized by the conservation of the total momentum and by hydrodynamic transport. Here, the authors report experimental evidence for such a coupled electron-phonon liquid in NbGe2.www.nature.com/articles/s41467-021-25547-x
