Quantum criticality at cryogenic melting of polar bubble lattices
W. Luo, A. Akbarzadeh, Y. Nahas +2
Quantum fluctuations (QFs) caused by zero-point phonon vibrations (ZPPVs) are known to prevent the occurrence of polar phases in bulk incipient ferroelectrics down to 0K1-3. On the…
Energy storage properties of ferroelectric nanocomposites
Zhijun Jiang, Zhenlong Zhang, Sergei Prokhorenko +3
An atomistic effective Hamiltonian technique is used to investigate the finite-temperature energy storage properties of a ferroelectric nanocomposite consisting of an array of BaTi…
Hexagonal close-packed polar-skyrmion lattice in ultrathin ferroelectric PbTiO3 films
Shuai Yuan, Zuhuang Chen, Sergei Prokhorenko +7
Polar skyrmions are topologically stable, swirling polarization textures with particle-like characteristics, which hold promise for next-generation, nanoscale logic and memory. Whi…
Motion and teleportation of polar bubbles in ultra-thin ferroelectrics
S. Prokhorenko, Y. Nahas, Q. Zhang +3
Polar bubble domains are complex topological defects akin to magnetic skyrmions that can spontaneously form in ferroelectric thin films and superlattices. They can be deterministic…
Dynamics of polar vortex crystallization
Suyash Rijal, Yousra Nahas, Sergei Prokhorenko +1
Vortex crystals are commonly observed in ultra-thin ferroelectrics. However, a clear physical picture of origin of this topological state is currently lacking. Here, we show that v…
Dynamical control of topology in ferroelectric skyrmions via twisted light
Lingyuan Gao, Sergei Prokhorenko, Yousra Nahas +1
Twisted light carries a non-zero orbital angular momentum, that can be transferred from light to electrons and particles ranging from nanometers to micrometers. Up to now, the inte…
