Kondo Resilience: How Interactions Salvage Quantum Effects in One Dimension
![Yb atoms exhibit Kondo physics through a carefully engineered system where fermionic atoms in spin-1/2 states are selectively trapped - mobile in a ground band and localized in an excited band - creating an impurity interacting with a surrounding fermionic environment via both antiferromagnetic and potential interactions, effectively modeling [latex]Eq.

New research reveals that the Kondo effect, a hallmark of quantum impurity problems, can persist in one-dimensional systems even with strong scattering, thanks to the crucial role of environmental correlations.
