Anomalous and parallel Hall effects in ferromagnetic Weyl semimetal CrTe
Anumita Bose, Shubham Purwar, Setti Thirupathaiah +1
Recently, time-reversal symmetry broken magnetic Weyl semimetals (WSMs) have attracted extensive attention and have provided an intriguing platform for exploring fundamental physic…
Floquet engineering of topological semimetals with bicircularly polarized light
Maitri Ganguli, Aneek Jana, Awadhesh Narayan
We study the effect of illumination of bicircularly polarized light (BCL) on topological semimetals, namely multifold fermion and line-node semimetals. We demonstrate, by means of…
Dopant-induced modulation of ferroelectricity in perovskite nitride LaWN
Harshvardhan Singh Deora, Awadhesh Narayan
Perovskite nitrides are starting to be explored for their promising properties distinct from their oxide counterparts. Here, through first-principles density functional computation…
Emergence of tunable exceptional points in altermagnet-ferromagnet junctions
Md Afsar Reja, Awadhesh Narayan
The existence of exceptional points (EPs) where both eigenvalues and eigenvectors converge is a key characteristic of non-Hermitian physics. A newly-discovered class of…
Chirality-tunable non-linear Hall effect
Nesta Benno Joseph, Arka Bandyopadhyay, Awadhesh Narayan
The non-linear generalization of the Hall effect has recently gained much attention, with a rapidly growing list of non-centrosymmetric materials that display higher-order Hall res…
Interplay of altermagnetism and pressure in hexagonal and orthorhombic MnTe
Nayana Devaraj, Anumita Bose, Awadhesh Narayan
Alternative magnetic materials or ``altermagnets", characterized by their non-relativistic, momentum-dependent spin-split states, represent a cutting-edge advancement in the field…
Observation of quantum oscillations near the Mott-Ioffe-Regel limit in CaAs3
Yuxiang Wang, Minhao Zhao, Jinglei Zhang +24
The Mott-Ioffe-Regel limit sets the lower bound of carrier mean free path for coherent quasiparticle transport. Metallicity beyond this limit is of great interest because it is oft…
Non-linear Hall Effects: Mechanisms and Materials
Arka Bandyopadhyay, Nesta Benno Joseph, Awadhesh Narayan
This review presents recent breakthroughs in the realm of nonlinear Hall effects, emphasizing central theoretical foundations and recent experimental progress. We elucidate the qua…
