Bilinear magnon--exciton coupling in biased ferromagnetic electron--hole bilayers
Pieter M. Gunnink
The hybridization of magnons and excitons would combine magnetic and optical degrees of freedom in a single composite quasiparticle. Such a hybridization is however difficult to ac…
Magnetic noise of a dark exciton Bose-Einstein condensate
Pieter M. Gunnink
Excitons provide a promising platform for the realization of solid-state Bose-Einstein condensation (BEC), offering quantum coherence, strongly correlated electron-hole physics, an…
Floquet-induced anisotropic magnetoresistance and anomalous Hall effect in 2D -wave altermagnets with Rashba spin-orbit coupling
Mohsen Yarmohammadi, Pieter M. Gunnink, Jairo Sinova +1
Altermagnets (AMs) combine momentum-dependent spin splitting with zero net magnetization, making them promising for spintronics. Periodic driving enables dynamic symmetry engineeri…
Topological Magnon-Plasmon Hybrids
Tomoki Hirosawa, Pieter M. Gunnink, Alexander Mook
We study magnon-plasmon coupling in effectively two-dimensional stacks of van der Waals layers in the context of the band structure topology. Invoking the quasiparticle approximati…
Spin demons in d-wave altermagnets
Pieter M. Gunnink, Jairo Sinova, Alexander Mook
Demons are a type of plasmons, which consist of out-of-phase oscillations of electrons in different bands. Here, we show that -wave altermagnets, a recently discovered class of…
Surface acoustic wave driven acoustic spin splitter in d-wave altermagnetic thin films
Pieter M. Gunnink, Jairo Sinova, Alexander Mook
The generation of spin currents is a key challenge in the field of spintronics. We propose using surface acoustic waves (SAWs) to generate spin currents in altermagnetic thin films…
Nonequilibrium effects in spin-torque oscillators
Pieter M. Gunnink, Tim Ludwig, Alexander Shnirman +1
One of the cornerstones of spintronics is the application of a spin-transfer torque to a nanomagnet, driving the magnetization of the nanomagnet into a steady-state precession and…
Coupling of plasmons to the two-magnon continuum in antiferromagnets
Pieter M. Gunnink, Alexander Mook
The coupling of magnons and plasmons offers a promising avenue for hybrid quantum systems, facilitating coherent energy and information transfer between magnetic and charge excitat…
Electrical Non-Hermitian Control of Topological Magnon Spin Transport
Pieter M. Gunnink, Rembert A. Duine, Alexander Mook
Magnonic topological phases realize chiral edge spin waves that are protected against backscattering, potentially enabling highly efficient spin transport. Here we show that the sp…
Detection of Geometric Phases in Spin Waves using Nitrogen-Vacancy Centers
Tomas T. Osterholt, Pieter M. Gunnink, Rembert A. Duine
Due to their robustness, the implementation of geometric phases provides a reliable and controllable way to manipulate the phase of a spin wave, thereby paving the way towards func…
Magnon spin capacitor
Pieter M. Gunnink, Tim Ludwig, Rembert A. Duine
In this work we show that a magnon spin capacitor can be realized at a junction between two exchange coupled ferromagnets. In this junction, the buildup of magnon spin over the jun…
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…
Zero-frequency chiral magnonic edge states protected by non-equilibrium topology
Pieter M. Gunnink, Joren S. Harms, Rembert A. Duine +1
Topological bosonic excitations must, in contrast to their fermionic counterparts, appear at finite energies. This is a key challenge for magnons, as it prevents straightforward ex…
Non-linear dynamics of the non-Hermitian Su-Schrieffer-Heeger model
Pieter M. Gunnink, Benedetta Flebus, Hilary M. Hurst +1
We numerically determine the robustness of the lasing edge modes in a spin-torque oscillator array that realizes the non-Hermitian Su-Schrieffer-Heeger model. Previous studies foun…
Theory for electrical detection of the magnon Hall effect induced by dipolar interactions
Pieter M. Gunnink, Rembert A. Duine, Andreas Rückriegel
We derive the anomalous Hall contributions arising from dipolar interactions to diffusive spin transport in magnetic insulators. Magnons, the carriers of angular momentum in these…
Artificial oxide heterostructures with non-trivial topology
Pieter M. Gunnink, Rosa Luca Bouwmeester, Alexander Brinkman
In the quest for topological insulators with large band gaps, heterostructures with Rashba spin-orbit interactions come into play. Transition metal oxides with heavy ions are espec…
Electrical detection of unconventional transverse spin-currents in obliquely magnetized thin films
Pieter M. Gunnink, Rembert A. Duine, Andreas Rückriegel
In a typical experiment in magnonics, thin films are magnetized in-plane and spin waves only carry angular momentum along their spatial propagation direction. Motivated by the expe…
