Statics and dynamics of skyrmions interacting with disorder and nanostructures

C Reichhardt, CJO Reichhardt, MV Milošević - Reviews of Modern Physics, 2022 - APS
Magnetic skyrmions are topologically stable nanoscale particlelike objects that were
discovered in 2009. Since that time, intense research interest in the field has led to the …

Y Shen, Q Zhang, P Shi, L Du, X Yuan, AV Zayats - Nature Photonics, 2024 - nature.com
Skyrmions are topologically stable quasiparticles that have been predicted and
demonstrated in quantum fields, solid-state physics and magnetic materials, but only …

Prethermal Floquet time crystals in chiral multiferroic chains and applications as quantum sensors of AC fields

RK Shukla, L Chotorlishvili, SK Mishra, F Iemini - Physical Review B, 2025 - APS
We study the emergence of the prethermal Floquet time crystal (pFTC) in disordered chiral
multiferroic chains. The model is an extension of the usual periodically driven nearest …

Writing and deleting skyrmions with electric fields in a multiferroic heterostructure

CK Li, XP Yao, G Chen - Physical Review Research, 2021 - APS
Magnetic skyrmions are topological spin textures that can be used as information carriers for
the next-generation information storage and processing. The electric-field controlling of …

Synthetic spin dynamics with Bessel-Gaussian optical skyrmions

K Singh, P Ornelas, A Dudley, A Forbes - Optics Express, 2023 - opg.optica.org
Skyrmions are topologically stable fields that cannot be smoothly deformed into any other
field configuration that differs topologically, that is, one that possesses a different integer …

Electrically controlled entanglement of cavity photons with electromagnons

Z Toklikishvili, L Chotorlishvili, Y Zhou, SY **e, CJ Zhu, YP Yang - Physical Review B, 2022 - APS
We present a proposal to produce bipartite and tripartite entanglement in a hybrid magnon
cavity QED system. Two macroscopic yttrium iron garnet (YIG) spheres are coupled to a …

Dynamics of magnetic skyrmions under temperature gradients

C Gong, Y Zhou, G Zhao - Applied Physics Letters, 2022 - pubs.aip.org
We expand the Zhang–Li spin-transfer torque [Phys. Rev. Lett. 93, 127204 (2004)] to finite
temperatures by the scattering amplitude. Considering various factors, including the …

Commensuration effects on skyrmion Hall angle and drag for manipulation of skyrmions on two-dimensional periodic substrates

C Reichhardt, CJO Reichhardt - Physical Review B, 2022 - APS
We examine the dynamics of an individually driven skyrmion moving through a background
lattice of skyrmions coupled to a 2D periodic substrate as we vary the ratio of the number of …
