skyrmion การใช้

• These entities would later in 1982 became known as Skyrmion s.
• Theoretical solutions exist for both isolated skyrmions and skyrmion lattices.
• The "'chiral bag model "'merges the MIT bag model and the Skyrmion model.
• However, he is best known for formulating the first topological soliton to model a particle, the skyrmion.
• The Skyrmion models the nucleon as a topological soliton in a non-linear SU ( 2 ) pion field.
• In addition, they performed research on skyrmion lattices in the quantum Hall effect and collective modes in supersolid 4He.
• The device used arrays of magnetized cobalt disks as artificial Bloch skyrmion lattices atop a thin film of cobalt and palladium.
• In this model, a hole is punched out of the middle of the Skyrmion, and replaced with a bag model.
• In the most common formulation, the chiral bag model basically replaces the interior of the skyrmion with the bag of quarks.
• The topological stability of the Skyrmion is interpreted as the conservation of baryon number, that is, the non-decay of the nucleon.
• Depending on the magnetic interactions existing in a given system, the skyrmion topology can be a stable, meta-stable, or unstable solution when one minimizes the system's free energy.
• However, since the stability and behavioral attributes of skyrmions can vary significantly based on the type of interactions in a system, the word'skyrmion'can refer to substantially different magnetic objects.
• A skyrmion can be approximated by a soliton of the Sine-Gordon equation; after quantisation by the Bethe ansatz or otherwise, it turns into a fermion interacting according to the massive Thirring model.
• For this reason, some physicists choose to reserve use of the term'skyrmion'to describe magnetic objects with a specific set of stability properties, and arising from a specific set of magnetic interactions.
• Besides other notable achievements, landmark publications by Duine and his collaborators have led to the opening of new sub-fields of Physics, such as magnetic skyrmion spintronics, antiferromagnetic spintronics, and cold-atom spintronics.
• This type of skyrmion is known as a'hedgehog skyrmion .'In the case of fig . 1 ( b ), the progression of magnetization is helical, giving rise to what is often called a'vortex skyrmion .'

• Examples of topological solitons include the screw dislocation in a crystalline lattice, the Dirac string and the magnetic monopole in electromagnetism, the Skyrmion and the Wess Zumino Witten model in quantum field theory, the magnetic skyrmion in condensed matter physics, and cosmic strings and cosmology.
