Terahertz-field activation of polar skyrons
Huaiyu Wang, Vladimir Stoica, Cheng Dai +27
Unraveling collective modes arising from coupled degrees of freedom is crucial for understanding complex interactions in solids and developing new functionalities. Unique collectiv…
Non-reciprocal neutral ferroelectric domain walls in BiFeO3
M. A. P. Goncalves, M. Graf, M. Pasciak +1
This paper analyzes a peculiar phenomenon of non-reciprocal domain wall pairs and illustrate the implications in ab-initio-based atomistic computational experiments with (112)-orie…
Pyramidal charged domain walls in ferroelectric BiFeO
Pavel Marton, Marek Paściak, Mauro Gonçalves +4
Domain structures play a crucial role in the electric, mechanical and other properties of ferroelectric materials. In this study, we uncover the physical origins of the enigmatic z…
BiFeO nanoparticles at low-temperature using atomistic simulations -- surface charge distribution and terminations
Mauro A. P. Goncalves, Monica Graf, Marek Pasciak +1
This paper analyzes how the ferroelectric properties of cubic-like BiFeO nanoparticles are affected by different terminations and charge distributions at the surface using ab-i…
