A unique one-body position operator for periodic systems
Stefano Evangelisti, Faten Abu-Shoga, Celestino Angeli +2
In this work we proof that the one-body position operator for periodic systems that we have recently proposed [Phys. Rev. B 99, 205144] is unique modulo a phase factor and an addit…
Clifford Boundary Conditions for Periodic Systems: the Madelung Constant of Cubic Crystals in 1, 2 and 3 Dimensions
Nicolas Tavernier, Gian Luigi Bendazzoli, Véronique Brumas +2
In this work we demonstrate the robustness of a real-space approach for the treatment of infinite systems described with periodic boundary conditions that we have recently proposed…
The localization spread and polarizability of rings and periodic chains
Celestino Angeli, Gian Luigi Bendazzoli, Stefano Evangelisti +1
The localization spread gives a criterion to decide between metallic versus insulating behaviour of a material. It is defined as the second moment cumulant of the many-body positio…
Accurate ground-state energies of Wigner crystals from a simple real-space approach
Estefania Alves, Gian Luigi Bendazzoli, Stefano Evangelisti +1
We propose a simple and efficient real-space approach for the calculation of the ground-state energies of Wigner crystals in 1, 2, and 3 dimensions. To be precise, we calculate the…
