Subgap pumping of antiferromagnetic Mott insulators: photoexcitation mechanisms and applications
A self-consistent variational calculation of the driven 2D Hubbard model finds multiphoton-tunneling cooperation and dephasing-induced linear absorption in subgap-pumped Mott insulators, along with real-time feedback from gap renormalization.
