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…

Binding and spontaneous condensation of excitons in narrow-gap carbon nanotubes
Giacomo Sesti, Daniele Varsano, Elisa Molinari +1
Ultraclean, undoped carbon nanotubes are observed to be always insulating, even when the gap predicted by band theory is zero: the residual band gap is then thought to have a many-…
