Berry Curvature Dipole-induced Non-linear Hall Effect in Oxide Heterostructures
Nesta Benno Joseph, Arka Bandyopadhyay, Ajit C. Balram +1
The observation of non-linear Hall effects in time-reversal invariant systems has established the intriguing role of band topology beyond Berry curvature in determining transport p…
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…
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…
Berry Curvature Dipole and its Strain Engineering in Layered Phosphorene
Arka Bandyopadhyay, Nesta Benno Joseph, Awadhesh Narayan
The emergence of the fascinating non-linear Hall effect intrinsically depends on the non-zero value of the Berry curvature dipole. In this work, we predict that suitable strain eng…
Giant superlinear power dependence of photocurrent based on layered TaNiS photodetector
Xianghao Meng, Yuhan Du, Wenbin Wu +16
Photodetector based on two-dimensional (2D) materials is an ongoing quest in optoelectronics. These 2D photodetectors are generally efficient at low illuminating power but suffer s…
Electrically switchable giant Berry curvature dipole in silicene, germanene and stanene
Arka Bandyopadhyay, Nesta Benno Joseph, Awadhesh Narayan
The anomalous Hall effect in time-reversal symmetry broken systems is underpinned by the concept of Berry curvature in band theory. However, recent experiments reveal that the nonl…
Tunable Topology and Berry Curvature Dipole in Transition Metal Dichalcogenide Janus Monolayers
Nesta Benno Joseph, Saswata Roy, Awadhesh Narayan
Janus transition metal dichalcogenides, with intrinsic mirror asymmetry, exhibit a wide array of interesting properties. In this work, we study Janus monolayers derived from WTe$_2…
Topological Properties of Bulk and Bilayer 2M WS: A First-Principles Study
Nesta Benno Joseph, Awadhesh Narayan
Recently discovered 2M phase of bulk WS was observed to exhibit superconductivity with a critical temperature of 8.8 K, the highest reported among superconducting transition me…
Anomalous band renormalization due to high energy in the colossal thermoelectric material KRhO
Susmita Changdar, G. Shipunov, N. B. Joseph +6
We report on low-energy electronic structure and electronic correlations of KRhO, studied using high-resolution angle-resolved photoemission spectroscopy (ARPES) techn…
