Computing at the Edge Enabled by Indoor Photovoltaics and Ferroelectrics
Robert L. Z. Hoye, Markus Hellenbrand, Nuno Estrócio +17
The exponential, pervasive rise of artificial intelligence (AI), hosted in large data centres, will test the limits of the underpinning infrastructure, including electricity and wa…
Systematic generation of electron models for Second-Principles Density Functional Theory Methods
Nayara Carral-Sainz, Toraya Fernández-Ruiz, Jorge Íñiguez +2
We present a systematic, quasi-automated methodology for generating electronic models in the framework of second-principles density functional theory (SPDFT). This approach enables…
Tunable and Persistent Macroscopic Polarization in Nominally Centrosymmetric Defective Oxides
D. -S. Park, N. Pryds, N. Gauquelin +8
Introducing symmetry breaking in materials enables the emergence of functionalities. This can be microscopically and macroscopically driven by applying external stimuli such as mec…
Trilinear coupling and toroidicity in multiferroics
Andrea Urru, Alessio Filippetti, Jorge Íñiguez-Gonzàlez +1
Magnetoelectric responses are related in general to magnetic multipoles, and in particular the off-diagonal linear response is proportional to the toroidization order parameter. In…
