Vibrational modes of massive Skyrmions within the rational map ansatz [PDF]
, 2007 In this thesis, we study the vibrational modes of some Skyrmion solutions within the rational map approximation. When the Skyrme field is perturbed around a static solution, the radial and angular vibrations of the field are decoupled; this gives us two ...

Advanced Electronic Materials, EarlyView.Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.

Skyrmions and the nuclear force [PDF]
Physical Review C, 1993 The derivation of the nucleon-nucleon force from the Skyrme model is reexamined. Starting from previous results for the potential energy of quasistatic solutions, we show that a calculation using the Born-Oppenheimer approximation properly taking into account the mixing of nucleon resonances, leads to substantial central attraction.

Antiferromagnetic Skyrmions and Bimerons
, 2021 The topological spin textures, such as magnetic skyrmions and bimerons, are currently a hot topic in condensed matter physics. Magnetic skyrmions are swirling spin textures, which can be stabilized in chiral magnets with perpendicular magnetic anisotropy,

High-frequency spin transfer nano-oscillator based on the motion of skyrmions in an annular groove
New Journal of Physics, 2020 Magnetic skyrmion-based spin transfer nano-oscillators (STNOs) have been proposed as microwave signal generators and attracted enormous interest recently. However, the oscillation frequency of skyrmion-based STNOs is about 2 GHz, which is not so high for

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation
Advanced Intelligent Systems, EarlyView.Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Paths to annihilation of first- and second-order (anti)skyrmions via (anti)meron nucleation on the frustrated square lattice [PDF]
, 2019 We study annihilation mechanisms of small first- and second-order skyrmions and antiskyrmions on the frustrated J1−J2−J3 square lattice with broken inversion symmetry (Dzyaloshinskii-Moriya interaction).
