Strong enhancements to superconducting properties of one-dimensional systems from metallic reservoirs
Abstract
Using an asymmetric two-leg ladder comprising pairing and metallic chains, this Letter proves the striking power of reservoir-mediated boosting of superconductivity. Using many-body numerics on large systems at zero and finite temperature, we unravel the processes by which the metal parameters can impact the effective pairing strength and the ranged pair-pair coupling mediated by the metal. These then enhance key superconducting properties far above those of the isolated system. Thus, our Letter identifies a general mechanism by which reservoirs can strongly suppress the effects of the Mermin-Wagner theorem in finite-sized systems, allowing even large one-dimensional systems to appear practically ordered.
