Charge conservation in spin torque oscillators leads to a self-induced torque
Pieter M. Gunnink, Tim Ludwig, Rembert A. Duine
Spin torque oscillators are conventionally described by the Landau-Lifshitz-Gilbert-Slonczewski (LLGS) equation. However, at the onset of oscillations, the predictions of the conve…
The fractional Landau-Lifshitz-Gilbert equation
Robin C. Verstraten, Tim Ludwig, Rembert A. Duine +1
The dynamics of a magnetic moment or spin are of high interest to applications in technology. Dissipation in these systems is therefore of importance for improvement of efficiency…
Hydrodynamics of charged two-dimensional Dirac systems II: the role of collective modes
Kitinan Pongsangangan, T. Ludwig, H. T. C. Stoof +1
We study the hydrodynamic properties of ultraclean interacting two-dimensional Dirac electrons with Keldysh quantum field theory. We study it from a weak-coupling and a strong-coup…
Dissipation-free modes in dissipative systems
Daan van Seters, Tim Ludwig, Huaiyang Y. Yuan +1
The coupling between a system and its environment (or bath) always leads to dissipation. We show, however, that a system composed of two subsystems can have a dissipation-free mode…
Breaking of Coulomb blockade by macrospin-assisted tunneling
Tim Ludwig, Rembert A. Duine
A magnet with precessing magnetization pumps a spin current into adjacent leads. As a special case of this spin pumping, a precessing macrospin (magnetization) can assist electrons…
Current noise geometrically generated by a driven magnet
Tim Ludwig, Igor S. Burmistrov, Yuval Gefen +1
We consider a non-equilibrium cross-response phenomenon, whereby a driven magnetization gives rise to electric shot noise (but no d.c. current). This effect is realized on a nano-s…
