Floquet scattering and Fano resonances in nodal-ring and multi-Weyl semimetals: Role of propagating and evanescent modes
Sandip Bera, Ipsita Mandal
We develop a comprehensive Floquet scattering theory for quantum transport in periodically driven nodal-ring semimetals (NRSs) and multi-Weyl semimetals (mWSMs), extending our earl…

Phase-Shifted Planar Hall and Magnetoresistive Responses in Weyl Semimetals
Sandip Bera, Sudhansu S. Mandal
The planar Hall resistivity and magnetoresistivity of Weyl semimetals are conventionally expected to exhibit and angular dependences, respectively, where is…

Spin-Flux Skyrmions: Anomalous Electron Dynamics and Spin-Hall Currents
Sandip Bera, Sajeev John
We introduce a topologically distinct skyrmion, termed a spin-flux skyrmion, which shares the same real-space magnetization profile as a conventional skyrmion but differs fundament…
