# Nonlocal annihilation of Weyl fermions in correlated systems

@article{Crippa2019NonlocalAO, title={Nonlocal annihilation of Weyl fermions in correlated systems}, author={Luca Crippa and Adriano Amaricci and Niklas Wagner and Giorgio Sangiovanni and Jan Carl Budich and Massimo Capone}, journal={Physical Review Research}, year={2019} }

Weyl semimetals (WSMs) are characterized by topologically stable pairs of nodal points in the band structure, that typically originate from splitting a degenerate Dirac point by breaking symmetries such as time reversal or inversion symmetry. Within the independent electron approximation, the transition between an insulating state and a WSM requires the local creation or annihilation of one or several pairs of Weyl nodes in reciprocal space. Here, we show that strong electron-electron…
