Finite-frequency spin conductance of a ferro-/ferrimagnetic-insulator|normal-metal interface
David A. Reiss, Piet W. Brouwer
The interface between a ferro-/ferrimagnetic insulator and a normal metal can support spin currents polarized collinear with and perpendicular to the magnetization direction. The f…
Ultrafast demagnetization of iron induced by optical vs terahertz pulses
A. L. Chekhov, Y. Behovits, J. J. F. Heitz +7
We study ultrafast magnetization quenching of ferromagnetic iron following excitation by an optical vs a terahertz pump pulse. While the optical pump (photon energy of 3.1 eV) indu…
Theory of spin-Hall magnetoresistance in the AC (terahertz) regime
David A. Reiss, Tobias Kampfrath, Piet W. Brouwer
In bilayers consisting of a normal metal (N) with spin-orbit coupling and a ferromagnet (F), the combination of the spin-Hall effect, the spin-transfer torque, and the inverse spin…
Laser-induced terahertz spin transport in magnetic nanostructures arises from the same force as ultrafast demagnetization
R. Rouzegar, L. Brandt, L. Nadvornik +9
Laser-induced terahertz spin transport (TST) and ultrafast demagnetization (UDM) are central but so far disconnected phenomena in femtomagnetism and terahertz spintronics. Here, we…
Quantum robustness of fracton phases
M. Mühlhauser, M. R. Walther, D. A. Reiss +1
The quantum robustness of fracton phases is investigated by studying the influence of quantum fluctuations on the X-Cube model and Haah's code, which realize a type-I and type-II f…
Quantum robustness and phase transitions of the 3D Toric Code in a field
D. A. Reiss, K. P. Schmidt
We study the robustness of 3D intrinsic topogical order under external perturbations by investigating the paradigmatic microscopic model, the 3D toric code in an external magnetic…
Quantum phase transitions to topological Haldane phases in spin-one chains studied by linked-cluster expansions
P. Adelhardt, J. Gritsch, M. Hille +2
We use linked-cluster expansions to analyze the quantum phase transitions between symmetry unbroken trivial and topological Haldane phases in two different spin-one chains. The fir…
