摘要: The heat carriers responsible for the unexpectedly large thermal Hall conductivity of cuprate Mott insulator La$_2$CuO$_4$ were recently shown to be phonons. However, mechanism by which phonons in cuprates acquire chirality a magnetic field is still unknown. Here, we report similar two insulators with significantly different crystal structures and orders - Nd$_2$CuO$_4$ Sr$_2$CuO$_2$Cl$_2$ show that potential mechanisms can excluded scattering rare-earth impurities structural domains. Our comparative study further reveals orthorhombicity, apical oxygens, tilting oxygen octahedra canting spins out CuO$_2$ planes are not essential chirality. findings point chiral coming from coupling acoustic intrinsic excitations planes.
