Temperature as a Tunable Knob for Single-Channel Resonances in Ultracold Quantum GasesThis paper proposes a temperature-controlled resonance (TCR) mechanism in heteronuclear quantum gas mixtures, where thermal smearing of the Fermi surface reshapes the Casimir-like mediated interaction between impurities, enabling continuously tunable single-channel resonances.
