First-principles real-space embedding theory of the superconducting proximity effect
Nicolas Baù, Nicolas Baù, Mitra Dowlatabadi +3
When a superconductor is placed in contact with a normal material, Cooper pairs penetrate the latter and induce superconductivity via the proximity effect. Despite its central role…

Fluctuations and Correlations of Local Topological Order Parameters in Disordered Two-dimensional Topological Insulators
Roberta Favata, Nicolas Baù, Antimo Marrazzo
Two-dimensional topological insulators are characterized by an insulating bulk and conductive edge states protected by the nontrivial topology of the bulk electronic structure. The…

Theory of local topological markers for finite and periodic two-dimensional systems
Nicolas Baù, Antimo Marrazzo
The topological phases of two-dimensional time-reversal symmetric insulators are classified by a topological invariant. Usually, the invariant is introduced and ca…
