Hidden chiral signatures in ferroaxial K2Zr(PO4)2
Nora Taufertshöfer, Awadhesh Narayan, Nicola A. Spaldin
We use first-principles calculations and multipole analyses to demonstrate the relationship between ferroaxiality and chirality in the prototypical ferroaxial material K2Zr(PO4)2.…
Transport Evidence of Magnetic Polarization in the Altermagnetic Candidate MnTe
Younes Ghorbani, Nayana Devaraj, Joshua Maile +7
The paper reports epitaxial growth of α‑MnTe thin films that exhibit a finite magnetic polarization, evidenced by hysteretic butterfly longitudinal magnetoresistance and nonlinear…
Electric field induced Berry curvature dipole in quasi-one-dimensional BiI
Amiya Mondal, Awadhesh Narayan
The paper uses first‑principles calculations to study how an out‑of‑plane electric field can tune the Berry curvature dipole and nonlinear Hall response in monolayer and bilayer Bi…
Light-tunable quantum metric non-linear Hall response in Berry dipole semimetals
Debashree Chowdhury, Awadhesh Narayan
We investigate the effect of light on quantum metric-mediated intrinsic nonlinear Hall conductivity in Berry dipole semimetals. We discover that light induces a tunable asymmetry i…
Nonlinear Hall Effect in Metal-Organic Frameworks
Sarbajit Mazumdar, Jagadish N S, Awadhesh Narayan +3
We propose metal-organic frameworks (MOFs) as tunable platforms for nonlinear Hall responses. A universal analytical downfolding scheme maps -symmetric frameworks onto star- a…
The Bott Metric: A Real-Space Bridge Between Topology and Quantum Metric
Kaustav Chatterjee, Ronika Sarkar, Md Afsar Reja +1
The Bott index has become an indispensable tool to probe the topology of quantum matter, particularly in systems lacking translational symmetry. Constructed from a plaquette operat…
