Uniaxial strain-driven ferroelastic domain control in LaAlO3
Matthias Roeper, Robin Buschbeck, Jakob Wetzel +15
Multiferroic domain walls in functional oxides exhibit properties distinct from the bulk and are increasingly exploited as active elements in nanoelectronic and photonic devices. D…

A real-time approach to frequency-mixing spectroscopies: application to sum and difference frequency generation in two-dimensional crystals
Mike N. Pionteck, Myrta Grüning, Simone Sanna +1
We propose a computational framework to extract non-linear response functions from real-time simulations in the presence of more than one external field. We apply this approach to…

A convex lifting approach for the Calderón problem
Giovanni S. Alberti, Romain Petit, Simone Sanna
The Calderón problem consists in recovering an unknown coefficient of a partial differential equation from boundary measurements of its solution. These measurements give rise to a…
