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…
Majorana modes in graphene strips: polarization, wavefunctions, disorder, and Andreev states
Shubhanshu Karoliya, Sumanta Tewari, Gargee Sharma
Topologically protected Majorana zero modes (MZMs) have attracted intense interest due to their potential application in fault-tolerant quantum computation (TQC). Graphene nanoribb…
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…
Chiral Anomaly Induced Transverse Planar Transport Phenomena in Three Dimensional Spin-Orbit Coupled Metals
Rishi G. Gopalakrishnan, Binayyak B. Roy, Gargee Sharma +1
We investigate linear and nonlinear transverse planar transport phenomena (viz. linear and nonlinear Hall and Nernst coefficients) induced by chiral anomaly in three-dimensional sp…
Majorana polarization in disordered heterostructures
Shubhanshu Karoliya, Sumanta Tewari, Gargee Sharma
Recent studies propose Majorana polarization (MP) as a tool for identifying topological Majorana bound states (MBS). We analyze MP in two systems: a one-dimensional (1d) semiconduc…
