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…
A viable and accurate route to GW simulations of metals and doped semiconductors
Giacomo Sesti, Alberto Guandalini, Andrea Ferretti +4
In this work we present an efficient and fully ab-initio approach for the calculation of the screened Coulomb potential, specifically designed for two dimensional (2D) and three di…
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-…
Anomalous screening in narrow-gap carbon nanotubes
Giacomo Sesti, Daniele Varsano, Elisa Molinari +1
The screening of Coulomb interaction controls many-body physics in carbon nanotubes, as it tunes the range and strength of the force that acts on charge carriers and binds electron…
Non-adiabatic suppression of 3D excitonic screening in black phosphorus by mid-infrared pulses
Angela Montanaro, Francesca Giusti, Matteo Zanfrognini +10
The competition between the electron-hole Coulomb attraction and the three-dimensional dielectric screening dictates the optical properties of layered semiconductors. In low-dimens…
Evidence for equilibrium excitons and exciton condensation in monolayer WTe2
Bosong Sun, Wenjin Zhao, Tauno Palomaki +14
A single monolayer of the layered semimetal WTe2 behaves as a two-dimensional topological insulator, with helical conducting edge modes surrounding a bulk state that becomes insula…
