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…
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…
Floquet-Engineered Valley-Topotronics in Kekulé-Y Bond Textured Graphene Superlattice
Sushmita Saha, Alestin Mawrie
The exquisite distortion in a Kekulé-Y (Kek-Y) superlattice merges the two inequivalent Dirac cones (from the - and the - points) into the highest symmetric -point…
Magnetoresistive RAM with n-doped AlGaAs/GaAs writing/reading channels
Sushmita Saha, Deepak Sain, Alestin Mawrie
We show that the tunable gate voltage in n-doped AlGaAs/GaAs QW (quantum well) is a key in designing an efficient and ultrafast MRAM (magnetoresistive random access memory). The Ra…
Quantum anomalous Hall phase and effective in-plane Lande-g factor in an inverted InAs/GaSb quantum well
Sushmita Saha, Alestin Mawrie
The inverted band structure discovered in InAs/GaSb quantum well (QW) is found to host the topological quantum spin Hall (QSH) states. A QSH insulator hosts counterpropagating spin…
