Lorentz-Covariant Landau Levels of Tilted Dirac Fermions in Nonuniform Fields

Sushmita Saha, Alestin Mawrie

We develop an analytical theory of Landau quantization for tilted anisotropic Dirac fermions in an exponentially decaying magnetic field. Using anisotropy scaling and a Lorentz tra…

Topological Scaling of Nonlinear Injection current and the Quantized Circular Photogalvanic Effect (CPGE)in tilted multi Weyl semimetals(mWSMs)

Deepannita Das, Alestin Mawrie

We develop a microscopic theory of nonlinear magneto-optical injection currents in multi-Weyl semimetals subjected to a uniform magnetic field. Using the Landau-level spectrum of a…

A Quantum Framework for Negative Magnetoresistance in Multi-Weyl Semimetals

Arka Ghosh, Sushmita Saha, Alestin Mawrie

We develop a fully quantum-mechanical theory of negative magnetoresistance in multi-Weyl semimetals in the configuration, where the chiral anomaly is acti…

Enhanced Gilbert Damping via Cubic Spin-Orbit Coupling at 2DHG/Ferromagnetic Insulator Interface

Sushmita Saha, Alestin Mawrie

We investigate the enhancement of Gilbert damping at 2DHG/ferromagnetic insulator (FI) interfaces, where spin pumping from the FI layer injects spins into the 2DHG, and cubic Rashb…

Unveiling the Chiral States in Multi-Weyl Semimetals through Magneto-Optical Spectroscopy

Sushmita Saha, Deepannita Das, Alestin Mawrie

This study investigates the transport parameters in multi-Weyl semimetals, focusing on their magneto-optical properties and the role of chiral states. The tilting parameter is iden…
