Dynamical Tunneling Blockade in Layer-Pseudospin Ferromagnets
Lingxian Kong, Yuta Murakami, Ryuichi Shindou +1
Double-layer systems with narrow or flat electronic bands may exhibit spontaneous interlayer coherence, described by a layer-pseudospin ferromagnetic order parameter. In modern rea…
Optical signatures of dynamical excitonic condensates
Alexander Osterkorn, Yuta Murakami, Tatsuya Kaneko +3
We theoretically study dynamical excitonic condensates occurring in bilayers with an imposed chemical potential difference and in photodoped semiconductors. We show that optical sp…
Chirped amplitude mode in photo-excited superconductors
Thomas Blommel, Jason Kaye, Yuta Murakami +2
Using a state-of-the-art numerical scheme, we show that the Higgs mode under excitation exhibits chirped oscillations and exponential decay when fluctuations are included. This is…
Dynamical exciton condensates in biased electron-hole bilayers
Zhiyuan Sun, Yuta Murakami, Tatsuya Kaneko +2
Bilayer materials may support interlayer excitons comprised of electrons in one layer and holes in the other. In experiments, a non-zero exciton density is typically sustained by a…
Bulk photovoltaic effect in antiferromagnet: Role of collective spin dynamics
Junta Iguchi, Hikaru Watanabe, Yuta Murakami +2
Inspired by recent advancements in the bulk photovoltaic effect which can extend beyond the independent particle approximation (IPA), this study delves into the influence of collec…
