Generalized s-d model for Wannier-Mott excitons in layered magnetic semiconductors
Sonu Verma, Bashab Dey, Akashdeep Kamra
The recent discovery of excitons coupled to the magnetic order, and the consequent strong magneto-optic responses, in some van der Waals magnetic semiconductors has triggered inten…
Quantum sensing composite excitations in an anisotropic ferromagnet via a qubit
Amey S. Rodge, Tarek Moussa, Akashdeep Kamra +1
Ordered magnets harbor intrinsically squeezed ground states and magnonic excitations characterized by entanglement between spins and nonclassical magnon number composition. A pathw…
Microwave-to-optical transduction using magnon-exciton coupling in a layered antiferromagnet
Pratap Chandra Adak, Iris McDaniel, Suvodeep Paul +12
Coherent interfaces between microwave-frequency quantum systems and low-loss optical links are essential for quantum networks. However, existing microwave-optical transducers often…
Unquenched orbital angular momentum as the origin of spin inertia
Tarek Moussa, Darpa Narayan Basu, Ritwik Mondal +1
The recent proposal and observation of spin inertia, and the consequent high-frequency spin nutation mode, have raised key questions for our understanding of magnetization dynamics…
Quantum sensing magnonic number states using a bosonic mode as the probe
Bashab Dey, Sonu Verma, Mathias Weiler +1
Sensing number states of a magnonic mode has been accomplished using a superconducting qubit by realizing an effective dispersive interaction between the two systems. Here, we theo…
Magnon-polaron control in a surface magnetoacoustic wave resonator
Kevin Künstle, Yannik Kunz, Tarek Moussa +6
Strong coupling between distinct quasiparticles in condensed matter systems gives rise to hybrid states with emergent properties. We demonstrate the hybridization of confined phono…
Misfit layer superconductors, tuneable bulk heterostructures with strong 2D effects
Tomas Samuely, Martin Gmitra, Tristan Cren +2
Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are determined by two-dimensionality and strongly affected by interfa…
Inductive magnon noise spectroscopy
Luise Siegl, Richard Schlitz, Jamal Ben Youssef +6
State tomography allows to characterize quantum states, and was recently applied to reveal the dynamic magnetization state of a parametrically driven magnet. The identification of…
Thermodynamic properties of a superconductor interfaced with an altermagnet
Simran Chourasia, Aleksandr Svetogorov, Akashdeep Kamra +1
Recently introduced magnetic materials called altermagnets (AM) feature zero net magnetization but a momentum dependent magnetic exchange field, which can have intriguing implicati…
Electrically induced angular momentum flow between separated ferromagnets
Richard Schlitz, Matthias Grammer, Tobias Wimmer +7
Converting angular momentum between different degrees of freedom within a magnetic material results from a dynamic interplay between electrons, magnons and phonons. This interplay…
Temperature-dependent spin-transport and current-induced torques in superconductor/ferromagnet heterostructures
Manuel Müller, Lukas Liensberger, Luis Flacke +6
We investigate the injection of quasiparticle spin currents into a superconductor via spin pumping from an adjacent FM layer.To this end, we use NbN/\ch{Ni80Fe20}(Py)-heterostr…
Angle resolved relaxation of spin currents by antiferromagnets in spin valves
Dmytro M. Polishchuk, Akashdeep Kamra, Taras I. Polek +2
We observe and analyze tunable relaxation of a pure spin current by an antiferromagnet in spin-valves. This is achieved by carefully controlling the angle between a resonantly exci…
Spin-flip Enhanced Thermoelectricity in Superconductor-Ferromagnet Bilayers
A. Rezaei, A. Kamra, P. Machon +1
We study the effects of spin-splitting and spin-flip scattering in a superconductor (S) on the thermoelectric properties of a tunneling contact to a metallic ferromagnet (F) using…
