Generation of current vortex by spin current in Rashba systems
Florian Lange, Satoshi Ejima, Junji Fujimoto +4
Employing unbiased large-scale time-dependent density-matrix renormalization-group simulations, we demonstrate the generation of a charge-current vortex via spin injection in the R…
Photoinduced -pairing at finite temperatures
Satoshi Ejima, Tatsuya Kaneko, Florian Lange +2
We numerically prove photoinduced -pairing in a half-filled fermionic Hubbard chain at both zero and finite temperature. The result, obtained by combining the matrix-product-sta…
Bistabilities and domain walls in weakly open quantum systems
Florian Lange, Achim Rosch
Weakly pumped systems with approximate conservation laws can be efficiently described by a generalized Gibbs ensemble if the steady state of the system is unique. However, such a d…
Photoinduced -pairing in One-dimensional Mott Insulators
Satoshi Ejima, Tatsuya Kaneko, Florian Lange +2
Employing the density-matrix renormalization group technique in the matrix-product-state representation, we investigate the photoexcited superconducting correlations induced by the…
Block-Lanczos density-matrix renormalization-group approach to spin transport in Heisenberg chains coupled to leads
F. Lange, S. Ejima, T. Shirakawa +2
We adapt the block-Lanczos density-matrix renormalization-group technique to study the spin transport in a spin chain coupled to two non-interacting fermionic leads. As an example,…
