Multiband charge density wave exposed in a transition metal dichalcogenide
Árpád Pásztor, Alessandro Scarfato, Marcello Spera +5
In the presence of multiple bands, well-known electronic instabilities may acquire new complexity. While multiband superconductivity is the subject of extensive studies, the possib…

Insight into the charge density wave gap from contrast inversion in topographic STM images
Marcello Spera, Alessandro Scarfato, Árpad Pásztor +3
Charge density waves (CDWs) are understood in great details in one dimension, but they remain largely enigmatic in two dimensional systems. In particular, numerous aspects of the a…

Holographic imaging of the complex charge density wave order parameter
Árpád Pásztor, Alessandro Scarfato, Marcello Spera +3
The charge density wave (CDW) in solids is a collective ground state combining lattice distortions and charge ordering. It is defined by a complex order parameter with an amplitude…
