Berry curvature dipole generation and nonreciprocal spin photocurrents in ferroelectricity polarized heterostructures

Berry curvature dipole (BCD) describes the dipole-like distribution of Berry curvature in momentum space and plays a key role for quantum geometric phenomena in nonlinear optoelectronics. Experimentally, BCD can be generated at artificially designed semiconductor heterointerfaces...

Real‐Space Mapping of Emergent Correlated Electronic States With Scanning SQUID Microscopy

ABSTRACT Scanning superconducting quantum interference device (SQUID) microscopy provides ultrahigh magnetic field sensitivity and has emerged as a powerful real‐space probe for correlated quantum phenomena in condensed matter. By reducing the superconducting loop to submicron re...
