Dynamic disentanglement of photoflexoelectricity and flexophotovoltage
Zhiguo Wang, Yuanyang Guo, Zhenggang Rao +4
The coupling between light and strain gradients shows two kinds of effects: light enhanced flexoelectricity (photoflexoelectricity) and gradient enhanced photovoltage (flexophotovo…
Abinit 2025: New Capabilities for the Predictive Modeling of Solids and Nanomaterials
Matthieu J. Verstraete, Joao Abreu, Guillaume E. Allemand +71
Abinit is a widely used scientific software package implementing density functional theory and many related functionalities for excited states and response properties. This paper p…
Magnetoelectricity of Topological Solitons in 2D Magnets
Alexander Edström, Paolo Barone, Silvia Picozzi +1
We develop a multiscale approach to magnetoelectric effects, bridging atomistic and continuum models, with all parameters determined from ab initio electronic structure calculation…
Excess energy and countercurrents after a quantum kick
Nuria Santervás-Arranz, Massimiliano Stengel, Emilio Artacho
A quantum system of interacting particles under the effect of a static external potential is hereby described as kicked when that potential suddenly starts moving with a constant v…
Static Born charges and quantum capacitance in metals and doped semiconductors
Asier Zabalo, Cyrus E. Dreyer, Massimiliano Stengel
Born dynamical charges () play a key role in the lattice dynamics of most crystals, including both insulators and metals in the nonadiabatic ("clean") regime…
