Magnetically mediated hole pairing in fermionic ladders of ultracold atoms.

ABSTRACT: Conventional superconductivity emerges from pairing of charge carriers-electrons or holes-mediated by phonons¹. In many unconventional superconductors, the pairing mechanism is conjectured to be mediated by magnetic correlations², as captured by models of mobile charges in doped antiferromagnets³. However, a precise understanding of the underlying mechanism in real materials is still lacking and has been driving experimental and theoretical research for the past 40 years. Early theoretical studies predicted magnetic-mediated pairing of dopants in ladder systems^4-8, in which idealized theoretical toy models explained how pairing can emerge despite repulsive interactions⁹. Here we experimentally observe this long-standing theoretical pre
