Electric field induced Berry curvature dipole and non-linear anomalous Hall effects in higher wave symmetric unconventional magnets
Srimayi Korrapati, Snehasish Nandy, Sumanta Tewari
We investigate the second-order anomalous Hall response in two-dimensional higher-wave symmetric magnets, including the recently discovered class of collinear magnets known as alte…
Topological invariant for finite systems in the presence of disorder
Robert Eissele, Binayyak B. Roy, Sumanta Tewari +1
Topological invariants, rigorously defined only in the thermodynamic limit, have been generalized to topological indicators applicable to finite-size disordered systems. However, i…
Antibonding and Electronic Instabilities in GdRu2X2 (X = Si, Ge, Sn): A New Pathway Toward Developing Centrosymmetric Skyrmion Materials
Dasuni N. Rathnaweera, Xudong Huai, K. Ramesh Kumar +4
Chemical bonding is key to unlocking the potential of magnetic materials for future information technology. Magnetic skyrmions are topologically protected nano-sized spin textures…
Approximate half-integer quantization in anomalous planar transport in -wave altermagnets
Srimayi Korrapati, Snehasish Nandy, Sumanta Tewari
We investigate anomalous planar transport phenomena in a recently identified class of collinear magnetic materials known as -wave altermagnets. The anomalous planar effects mani…
