    "body_text": "The theoretical device places a floating Büttiker probe at the third terminal of a Sierpinski-gasket Aharonov-Bohm interferometer. That reservoir exchanges energy while carrying no net charge current. In the authors’ nonequilibrium Green’s-function model, magnetic-flux-controlled interference can cancel the base terminal’s differential heat response even as finite heat currents continue through the emitter and collector, causing the calculated thermal gain to diverge.\n\nThe mechanism depends on the combination of coherence and deliberately introduced dissipation; the purely coherent comparison showed little or no amplification. The paper proposes a mesoscopic heat-control principle rather than reporting a fabricated device, so the result is a model prediction whose experimental feasibility and stability remain to be established.",
