Emergent Superconductivity in Low Dimensions[electronic resource] /by Diane Ansermet. - 1st ed. 2018. - XXXIX, 165 p. 113 illus., 94 illus. in color.online resource. - Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053. - Springer Theses, Recognizing Outstanding Ph.D. Research,.

Superconductivity: History and Motivations -- Introduction and theory -- Experimental methods -- The quasi-one-dimensional Na2−δMo6Se6 -- The electronic normal state in Na2−δMo6Se6 -- Superconducting transition and pairing enhancement by disorder -- Reentrant phase coherence by Josephson coupling -- Summary and Outlook.

This book explores the relationship between electronic correlations, dimensionality, inhomogeneities, and superconductivity in low-dimensional systems by studying single crystals of the quasi-one-dimensional Na2-δMo6Se6, composed of MoSe filaments weakly coupled by Na atoms and subject to intrinsic disorder (δ > 0). It shows that the Na2-δMo6Se6 displays strong electronic correlations in its normal state, whereas a superconducting ground state emerges from Anderson localized electrons. Two novel behaviors of the superconducting state are observed: first, a disorder induced enhancement of the superconducting transition temperature; second, a reentrant phase coherence with increasing temperature, magnetic field, and current. It also analyzes the intrinsic properties of Na2-δMo6Se6 are analyzed to offer a thorough understanding of these phenomena. The emergence of superconductivity in such low-dimensional systems provides a fruitful playground to explore electronic order and correlations.
