Generation of magnetic skyrmions through pinning effect
Ji-Chong Yang, Qing-Qing Mao, Yu Shi
Based on analytical estimation and lattice simulation, a proposal is made that magnetic skyrmions can be generated through the pinning effect in 2D chiral magnetic materials, in ab…
Effective field theory of the Higgs mode in a two-dimensional dilute Bose gas
Ji-Chong Yang, Yu Shi
We investigate the spectral function of the Higgs mode in a two dimensional Bose gas, by using the effective field theory in the zero temperature limit. Our approach explains the e…
Shape of a skyrmion
Ji-Chong Yang, Qing-Qing Mao, Yu Shi
We propose a method of determining the shape of a two-dimensional magnetic skyrmion, which can be parameterized as the position dependence of the orientation of the local magnetic…
Higgs mode in dimensional model
Ji-Chong Yang, Yu Shi
We investigate the spectral functions of the Higgs mode in model, which can be experimentally realized in a 2D Bose gas. Zero temperature limit is considered. Our calculatio…
