Coupling-dependent rates of energy transfers from photoexcited Mott insulators to lattice vibrations

Kenji Yonemitsu, Nobuya Maeshima

Photoexcited states are relaxed by transferring energy to the environments. In order to study which coupling allows fast energy transfer to lattice vibrations in correlated electro…
