Nonreciprocal Magnon Hanle Effect in Antiferromagnetic -FeO
Janine Gückelhorn, Sebastián de-la-Peña, Monika Scheufele +8
The precession of the magnon pseudospin about the equilibrium pseudofield, the latter capturing the nature of magnonic eigenexcitations in an antiferromagnet, gives rise to the mag…
Role of photonic interference in exciton-mediated magneto-optic responses
Güven Budak, Christian Riedel, Akashdeep Kamra +4
Coupled optical and magnetic excitations can give rise to remarkably strong magneto-optic responses. This is particularly evident in van der Waals magnets, such as the antiferromag…
Excitons in van der Waals magnetic materials
Pratap Chandra Adak, Florian Dirnberger, Swagata Acharya +3
Two-dimensional magnetic semiconductors provide a unique materials platform in which long-range magnetic order coexists with strongly bound excitons. Because excitonic states and m…
Boltzmann transport theory of magnon-exciton drag
Zakhar A. Iakovlev, Akashdeep Kamra, Mikhail M. Glazov
We develop a microscopic theory of magnon-exciton drag effect in a bilayer van der Waals antiferromagnetic semiconductor CrSBr. Effective exciton-magnon coupling arises from an orb…
Twist-tuned exchange and hysteresis in a bilayer van der Waals magnet
Priyanka Mondal, Sonu Verma, Wenze Lan +9
Moiré superlattices in twisted bilayers enable profound reconstructions of the electronic bandstructure, giving rise to correlated states with remarkable tunability. Extending this…
Exciton transport driven by spin excitations in an antiferromagnet
Florian Dirnberger, Sophia Terres, Zakhar A. Iakovlev +5
A new class of optical quasiparticles called magnetic excitons recently emerged in magnetic van der Waals materials. Akin to the highly effective strategies developed for electrons…
Squeezing and quantum control of antiferromagnetic magnon pseudospin
Anna-Luisa E. Römling, Johannes Feist, Francisco J. García-Vidal +1
Antiferromagnets have been shown to harbor strong magnon squeezing in equilibrium, making them a potential resource for quantum correlations and entanglement. Recent experiments ha…
Non-reciprocity in magnon mediated charge-spin-orbital current interconversion
José Omar Ledesma-Martin, Edgar Galindez-Ruales, Sachin Krishnia +9
In magnetic systems, angular momentum is carried by spin and orbital degrees of freedom. Nonlocal devices, comprising heavy-metal nanowires on magnetic insulators like yttrium iron…
Magnon-mediated exciton-exciton interaction in a van der Waals antiferromagnet
Biswajit Datta, Pratap Chandra Adak, Sichao Yu +17
Excitons are fundamental excitations that govern the optical properties of semiconductors. Interacting excitons can lead to various emergent phases of matter and large nonlinear op…
Unconventional magnetism mediated by spin-phonon-photon coupling
Petros Andreas Pantazopoulos, Johannes Feist, Francisco J. García-Vidal +1
Magnetic order typically emerges due to the short-range exchange interaction between the constituent electronic spins. Recent discoveries have found a crucial role for spin-phonon…
Nonreciprocity of supercurrent along applied magnetic field
Filippo Gaggioli, Yasen Hou, Jagadeesh S. Moodera +1
Nonreciprocal current responses arise in a broad range of systems, from magnons and phonons to supercurrents, due to an interplay between spatial and temporal symmetry breakings. T…
Standing spin waves in Permalloy-NiO bilayers as a probe of the interfacial exchange coupling
Diego Caso, Ana García-Prieto, Eugenia Sebastiani-Tofano +4
Ferromagnetic/Antiferromagnetic (FM/AFM) bilayers dynamics have been a recent topic of interest due to the interaction occurring at the interface, where the magnetic moments of the…
Quantum Sensing of Antiferromagnetic Magnon Two-Mode Squeezed Vacuum
Anna-Luisa E. Römling, Akashdeep Kamra
Néel ordered antiferromagnets exhibit two-mode squeezing such that their ground state is a nonclassical superposition of magnon Fock states. Here we theoretically demonstrate that…
Superconducting spin valves based on antiferromagnet/superconductor/antiferromagnet heterostructures
G. A. Bobkov, V. M. Gordeeva, Lina Johnsen Kamra +4
Proximity effect at superconductor/antiferromagnet (S/AF) interfaces, which manifests itself as generation of Neel-type triplet correlations, leads to sensitivity of the supercondu…
Electrostatic nature of cavity-mediated interactions between low-energy matter excitations
Petros-Andreas Pantazopoulos, Johannes Feist, Akashdeep Kamra +1
The use of cavity quantum electrodynamical effects, i.e., of vacuum electromagnetic fields, to modify material properties in cavities has rapidly gained popularity and interest in…
Using superconductivity to control magnetism: a facet of superconducting spintronics
Lina Johnsen Kamra, Akashdeep Kamra
Magnets are used in electronics to store and read information. A magnetic moment is rotated to a desired direction, so that information can later be retrieved by reading this orien…
The role of electron-electron scattering in spin transport
Akashdeep Kamra, Bahniman Ghosh
We investigate spin transport in quasi 2DEG formed by III-V semiconductor heterojunctions using the Monte Carlo method. The results obtained with and without electron-electron scat…
