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…
Pyramidal charged domain walls in ferroelectric BiFeO
Pavel Marton, Marek PaÅciak, 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…
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…
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…
