Thermoelectric Signatures of Kondo Physics in Geometry‐Tunable Double Quantum Dots

The equilibrium thermoelectric and spectral properties of a double quantum dot system are investigated, with the geometry continuously tuned from series to parallel via a parameter . Within the noncrossing approximation in the infinite‐ limit, the Kondo peak remains robust, while satellite features and the Kondo temperature show strong sensitivity to the geometry. The Seebeck coefficient exhibits sign reversals and nonmonotonic behavior as a result of the interplay between Kondo and satellite peaks. These findings underscore the role of interference and coupling asymmetry in governing transport properties, suggesting routes for geometry‐based optimization in nanoscale devices.
