Friedel oscillations and chiral superconductivity in monolayer NbSe
Julian Siegl, Anton Bleibaum, Wen Wan +5
In 1965 Kohn and Luttinger proposed a genuine electronic mechanism for superconductivity. Despite the bare electrostatic interaction between two electrons being repulsive, in a met…
Ising domain wall networks from intertwined charge density waves in single-layer TiSe2
Wen Wan, Maria N. Gastiasoro, Daniel Muñoz-Segovia +3
When the period of an incommensurate charge density wave (ICDW) approaches an integer multiple of a lattice vector, the energy gain obtained from locking the period to the lattice…
Layer thickness and substrate effects on superconductivity in epitaxial FeSe films on BLG/SiC(0001)
Yongsong Wang, Haojie Guo, Ane Etxebarria +3
The layered nature and simple structure of FeSe reveal this iron-based superconductor as a unique building block for the design of artificial heterostructure materials. While super…
Atomic-scale mapping of superconductivity in the incoherent CDW mosaic phase of a transition metal dichalcogenide
Sandra Sajan, Haojie Guo, Tarushi Agarwal +6
The emergence of superconductivity in the octahedrally coordinated (1T) phase of TaS2 is preceded by the intriguing loss of long-range order in the charge density wave (CDW). Such…
