Binding and spontaneous condensation of excitons in narrow-gap carbon nanotubes
Giacomo Sesti, Daniele Varsano, Elisa Molinari +1
The paper theoretically demonstrates that all narrow‑gap carbon nanotubes become excitonic insulators, deriving how exciton binding energy scales with tube radius and chirality and…

Stabilization of sliding ferroelectricity through exciton condensation
Matteo D'Alessio, Daniele Varsano, Elisa Molinari +1
Sliding ferroelectricity is a phenomenon that arises from the insurgence of spontaneous electronic polarization perpendicular to the layers of two-dimensional (2D) systems upon the…
