Kondo breakdown induced by non-Hermitian complex hybridization
Kazuki Yamamoto, Masaya Nakagawa, Norio Kawakami
Recently, a non-Hermitian Anderson impurity model with one-body loss has been studied in [Phys. Rev. B 111, 125157 (2025)}], and it has been demonstrated that the renormalization e…

Correlation versus dissipation in a non-Hermitian Anderson impurity model
Kazuki Yamamoto, Masaya Nakagawa, Norio Kawakami
We analyze the competition between strong correlations and dissipation in quantum impurity systems from the Kondo regime to the valence fluctuation regime by developing a slave-bos…
