Quantum criticality in dimerised anisotropic spin-1 chains
Satoshi Ejima, Florian Lange, Holger Fehske
Applying the (infinite) density-matrix renormalisation group technique, we explore the effect of an explicit dimerisation on the ground-state phase diagram of the spin-1 chai…
Spin-charge conversion and current vortex in spin-orbit coupled systems
Junji Fujimoto, Florian Lange, Satoshi Ejima +4
Using response theory, we calculate the charge-current vortex generated by spin pumping at a point-like contact in a system with Rashba spin-orbit coupling. We discuss the spatial…
Finite-temperature photoemission in the extended Falicov-Kimball model: a case study for TaNiSe
Satoshi Ejima, Florian Lange, Holger Fehske
Utilizing the unbiased time-dependent density-matrix renormalization group technique, we examine the photoemission spectra in the extended Falicov-Kimball model at zero and finite…
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…
