Chiral anomaly and planar Hall conductance in pseudospin- Fermions
Azaz Ahmad
Positive longitudinal magnetoconductance (LMC) and planar Hall conductance (PHC) are hallmark transport signatures of the chiral anomaly in Weyl semimetals. Recent theoretical deve…
Semiclassical theory of frequency dependent linear magneto-optical transport in Weyl semimetals
Azaz Ahmad, Pankaj Bhalla, Snehasish Nandy +1
We develop a semiclassical Boltzmann theory for frequency-dependent magneto-optical transport in Weyl semimetals (WSMs), incorporating momentum-dependent relaxation via a scatterin…
Semiclassical magnetotransport in Weyl semimetals with skyrmion-induced emergent magnetic fields
Azaz Ahmad, Takami Tohyama
We investigate magnetotransport in a time-reversal symmetry-broken, untilted Weyl semimetal in the simultaneous presence of momentum-space Berry curvature and skyrmion-induced emer…
Chiral anomaly-induced nonlinear Hall effect in spin-orbit coupled noncentrosymmetric metals
Gautham Varma K, Mohd. Hashim Raza, Azaz Ahmad
Recent studies have shown that chiral anomaly is not limited to Weyl semimetals (WSMs), but are also shown by a larger class of materials called spin orbit coupled noncentrosymmetr…
Strain-induced Ettingshausen effect in spin-orbit coupled noncentrosymmetric metals
Gautham Varma K, Azaz Ahmad, Gargee Sharma
Elastic deformations couple with electronic degrees of freedom in materials to generate gauge fields that lead to interesting transport properties. Recently, it has been well studi…
Quasiclassical electron transport in topological Weyl semimetals
Azaz Ahmad
Weyl fermions are powerful yet simple entities that connect geometry, topology, and physics. While their existence as fundamental particles is still uncertain, growing evidence sho…
