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…
Floquet engineering of binding in doped and photo-doped Mott insulators
Madhumita Sarkar, Zala Lenarčič, Denis Golež
We investigate the emergence of bound states in chemically and photo-doped Mott insulators, mediated by spin and -pairing fluctuations within both 2-leg ladder and 2D systems. T…
Exciton-spin interactions in antiferromagnetic charge-transfer insulators
Tatsuya Kaneko, Yuta Murakami, Denis Golež +2
We derive exciton-spin interactions from a microscopic correlated model that captures important aspects of the physics of charge-transfer (CT) insulators to address magnetism assoc…
Decomposing imaginary time Feynman diagrams using separable basis functions: Anderson impurity model strong coupling expansion
Jason Kaye, Zhen Huang, Hugo U. R. Strand +1
We present a deterministic algorithm for the efficient evaluation of imaginary time diagrams based on the recently introduced discrete Lehmann representation (DLR) of imaginary tim…
Photo-induced charge-transfer renormalization in NiO
Tobias Lojewski, Denis Golez, Katharina Ollefs +21
Photo-doped states in strongly correlated charge transfer insulators are characterized by - and - interactions and the resulting intertwined dynamics of charge excitati…
Optical manipulation of bipolarons in a system with nonlinear electron-phonon coupling
K. Kovač, D. Golež, M. Mierzejewski +1
We investigate full quantum mechanical evolution of two electrons nonlinearly coupled to quantum phonons and simulate the dynamical response of the system subject to a short spatia…
