It is known that the loss of phase coherence of Cooper pairs in two-dimensional superconductivity corresponds to the unbinding of vortex-antivortex pairs with the quasi-long-range order in the order-parameter phase field, described by the Berezinskii-Kosterlizt-Thouless (BKT) transition of a 2D XY m…

The mechanism that drives nematic behaviour in iron-based superconductors is still unclear. Now, nematicity and anisotropy in spin excitations are shown to disappear at the same temperature, indicating that the transition is primarily spin-driven.Nature Physics, Published online: 19 May 2022; doi:10.1038/s41567-022-01606-y

Electrons in PdCoO2 can travel a long way before being scattered, and their band structure is such that they can travel in only one of three directions. As a result, the current flow through this nanoscale conductor can be very efficient.Nature Materials, Published online: 05 May 2022; doi:10.1038/s41563-022-01245-x

Spins become polarized along their momenta when travelling through chiral tellurium nanowires. The signs of chirality and current determine the orientations of polarized spins while the spin density can be tuned by electrical gating, current and external magnetic field.Nature, Published online: 04 May 2022; doi:10.1038/s41586-022-04514-6
