Unified Theory of the Anomalous and Topological Hall Effects with Phase Space Berry Curvatures
Nishchhal Verma, Zachariah Addison, Mohit Randeria
Hall experiments in chiral magnets are often analyzed as the sum of an anomalous Hall effect, dominated by momentum-space Berry curvature, and a topological Hall effect, arising fr…
Enhancing Perpendicular Magnetic Anisotropy in Garnet Ferrimagnet by Interfacing with Few-Layer WTe2
Guanzhong Wu1, Dongying Wang, Nishchhal Verma +11
Engineering magnetic anisotropy in a ferro- or ferrimagnetic (FM) thin film is crucial in spintronic device. One way to modify the magnetic anisotropy is through the surface of the…
Optical Spectral Weight, Phase Stiffness and Tc Bounds for Trivial and Topological Flat Band Superconductors
Nishchhal Verma, Tamaghna Hazra, Mohit Randeria
We present exact results that give insight into how interactions lead to transport and superconductivity in a flat band where the electrons have no kinetic energy. We obtain bounds…
Upper bounds on the superfluid stiffness and superconducting : Applications to twisted-bilayer graphene and ultra-cold Fermi gases
Tamaghna Hazra, Nishchhal Verma, Mohit Randeria
Understanding the material parameters that control the superconducting transition temperature is a problem of fundamental importance. In many novel superconductors, phase flu…
