Kittel law and domain formation mechanism in PbTiO/SrTiO superlattices
Fernando Gómez-Ortiz, Hugo Aramberri, Juan M. López +3
We report second-principles simulations on the structural and energetic properties of domains in (PbTiO)/(SrTiO) superlattices. For the explored layer thick…
Berezinskii-Kosterlitz-Thouless phases in ultra-thin PbTiO/SrTiO superlattices
Fernando Gómez-Ortiz, Pablo García-Fernández, Juan M. López +1
We study the emergence of Berezinskii-Kosterlitz-Thouless (BKT) phases in (PbTiO)/(SrTiO) superlattices by means of second-principles simulations. Beyond a threshol…
Melting of Polarization Vortices Crystals and Chiral Phase Transitions in Oxide Superlattices
Fernando Gómez-Ortiz, Pablo García-Fernández, Juan M. López +1
We study the equilibrium arrangements of polarization vortices in (PbTiO)/(SrTiO) superlattices by means of second-principles simulations. We find that, at low temp…
Order-disorder transitions in a polar vortex lattice
Linming Zhou, Cheng Dai, Peter Meisenheimer +9
Order-disorder transitions are widely explored in various vortex structures in condensed matter physics, i.e., in the type-II superconductors and Bose-Einstein condensates. In this…
Electric Field Control of Chirality
Piush Behera, Molly A. May, Fernando Gómez-Ortiz +18
Polar textures have attracted significant attention in recent years as a promising analog to spin-based textures in ferromagnets. Here, using optical second harmonic generation bas…
Emergent chirality in a polar meron to skyrmion phase transition
Yu-Tsun Shao, Sujit Das, Zijian Hong +10
Polar skyrmions are predicted to emerge from the interplay of elastic, electrostatic and gradient energies, in contrast to the key role of the anti-symmetric Dzyalozhinskii-Moriya…
