Role of isotropic and anisotropic Dzyaloshinskii-Moriya interaction on skyrmions, merons and antiskyrmions in the symmetric system
Sandip Bera
The lattice Hamiltonian with the presence of a chiral magnetic isotropic Dzyaloshinskii-Moriya interaction (DMI) in a square and hexagonal lattice is numerically solved to give the…

Topological Superconductivity by Engineering Noncollinear Magnetism in Magnet/ Superconductor Heterostructures: A Realistic Prescription for 2D Kitaev Model
Pritam Chatterjee, Sayan Banik, Sandip Bera +4
We report on a realistic and rather general scheme where noncollinear magnetic textures proximitized with the most common -wave superconductor can appear as the alternative to $…

Theory of skyrmion, meron, anti-skyrmion and anti-meron in chiral magnets
Sandip Bera, Sudhansu S. Mandal
We find closed-form solution of the Euler equation for a chiral magnet in terms of a skyrmion or a meron depending on the relative strengths of magnetic anisotropy and magnetic fie…
