The current burst of device concepts based on nanoscale domain-control in magnetically and electrically ordered systems motivates us to review the recent development in the design of domain engineered oxide heterostructures. The improved ability to d...

The ferroelectric phase transition in RMnO₃ breaks both Z₃ and Z₂ symmetries, giving rise to 6 structural domains. Topological protected vortices are formed at the junctions of all 6 domains, and the ferroelectric phase transition is closely related...

We study the transport and the superconducting dynamics in a layer of type II superconductor (SC) with a normal top layer that hosts a helical magnetic ordering that gives rise to spin-current-driven ferroelectric polarization. Proximity effects akin...

Mastering the variations in the stability of a polarization vortex is fundamental for the development of ferroelectric devices based on polarization vortex domain structures. Some phase field simulations were conducted on PbTiO₃ nanofilms with an ini...

Liquid crystal (LC) droplets are highly attractive for applications in privacy windows, optical switches, optical vortices, optical microresonators, microlenses, and biosensors due to their ease of fabrication and easy alignment at surfaces. This rev...

It is well known that bright vortex solitons are unstable in the ${\chi }^{\left(2\right)}$ nonlinear media due to the strong azimuthal modulation instability. To solve this problem, a quadratic (${\chi }^{\left(2\right)}$) $\mathrm{LiNb}{\mathrm{O}}_3$ ferroelectric crystal with a special kind of helical-period...
