Second order unfitted ghost-FEM for elliptic interface problems with applications to low-dimensional semiconductor devices
Clarissa Astuto, Giovanni Nastasi
We develop an unfitted ghost finite element method for elliptic interface problems with discontinuous diffusion coefficients and apply it to the electrostatic simulation of low-dim…

Low-noise Pauli-consistent ensemble Monte Carlo for graphene with electron-electron scattering
Tigran Zalinyan, Giovanni Nastasi
We investigate Pauli-consistent ensemble Monte Carlo simulations of graphene with explicit intraband electron-electron scattering. To reduce the cost of electron-electron proposal-…
