Quantum Skyrmion Liquid
Dhiman Bhowmick, Andreas Haller, Deepak S. Kathyat +2
Skyrmions are topological magnetic textures, mostly treated classically, studied extensively due to their potential spintronics applications due to their topological stability. How…
Stabilization of Biskyrmions by chiral interaction in centrosymmetric magnets
Deepak S. Kathyat, Pinaki Sengupta
We report a microscopic mechanism for stabilization of biskyrmions in nature by investigating a minimal classical spin lattice model with nearest neighbour ferromagnetic Heisenberg…
Engineering antiferromagnetic skyrmions and antiskyrmions at metallic interfaces
Arnob Mukherjee, Deepak S. Kathyat, Sanjeev Kumar
We identify a mechanism to convert skyrmions and antiskyrmions into their antiferromagnetic (AFM) counterparts via interfacial engineering. The key idea is to combine properties of…
Antiskyrmions and Bloch Skyrmions in Magnetic Dresselhaus Metals
Deepak S. Kathyat, Arnob Mukherjee, Sanjeev Kumar
We present a microscopic electronic description of how antiskyrmions can be stabilized in a Dresselhaus spin-orbit coupled magnetic metal. Furthermore, we show that the antiskyrmio…
Antiferromagnetic Skyrmion Crystals in the Rashba Hund's Model on Triangular Lattice
Arnob Mukherjee, Deepak S. Kathyat, Sanjeev Kumar
Motivated by the importance of antiferromagnetic skyrmions as building blocks of next-generation data storage and processing devices, we report theoretical and computational analys…
Antiferromagnetic Skyrmions and Skyrmion Density Wave in Rashba Hund's Insulator
Arnob Mukherjee, Deepak S. Kathyat, Sanjeev Kumar
We discover magnetic phases hosting highly-elusive and technologically important antiferromagnetic skyrmion quasiparicles in a model for Rashba-coupled Hund's insulator. The result…
Rashba-Zener mechanism for nanoscale skyrmions and topological metals
Deepak S. Kathyat, Arnob Mukherjee, Sanjeev Kumar
We report a microscopic electronic mechanism for nanoscale skyrmion formation and topological metalicity. The mechanism, which relies on combining the classic double-exchange (DE)…
New Microscopic Magnetic Hamiltonian for Exotic Spin Textures in Metals
Deepak S. Kathyat, Arnob Mukherjee, Sanjeev Kumar
We derive a new microscopic spin Hamiltonian for Rashba-coupled double exchange metals. The Hamiltonian consists of anisotropic interactions of the Dzyaloshinskii-Moriya (DM) and K…
