Topological edge and corner states in coupled wave lattices in nonlinear polariton condensates
Tobias Schneider, Wenlong Gao, Thomas Zentgraf +2
Topological states have been widely investigated in different types of systems and lattices. In the present work, we report on topological edge states in double-wave (DW) chains, w…
Dimensional crossover in spin Hall oscillators
Andrew Smith, Kemal Sobotkiewich, Amanatullah Khan +9
Auto-oscillations of magnetization driven by direct spin current have been previously observed in multiple quasi-zero-dimensional (0D) ferromagnetic systems such as nanomagnets and…
Low damping and microstructural perfection of sub-40nm-thin yttrium iron garnet films grown by liquid phase epitaxy
Carsten Dubs, Oleksii Surzhenko, Ronny Thomas +6
The field of magnon spintronics is experiencing an increasing interest in the development of solutions for spin-wave-based data transport and processing technologies that are compl…
Thermally driven two-magnet nano-oscillator with large spin-charge conversion
Bassim Arkook, Christopher Safranski, Rodolfo Rodriguez +8
Next-generation spintronic applications require material properties that can be hardly met by one material candidate. Here we demonstrate that by combining insulating and metallic…
Symmetry and localization properties of defect modes in magnonic superlattices
Rodolfo A. Gallardo, Tobias Schneider, Alejandro Roldán-Molina +5
Symmetry and localization properties of defect modes of a one-dimensional bi-component magnonic superlattice are theoretically studied. The magnonic superlattice can be seen as a p…
Self-stabilizing exchange-mediated spin transport
T. Schneider, D. Hill, A. Kákay +9
Long-range spin transport in magnetic systems can be achieved by means of exchange-mediated spin textures with robust topological winding -- a phenomenon referred to as spin superf…
Flat Bands, Indirect Gaps, and Unconventional Spin-Wave Behavior Induced by a Periodic Dzyaloshinskii-Moriya Interaction
R. A. Gallardo, D. Cortés-Ortuño, T. Schneider +7
Periodically patterned metamaterials are known for exhibiting wave properties similar to the ones observed in electronic band structures in crystal lattices. In particular, periodi…
Spin caloritronic nano-oscillator
Chris Safranski, Igor Barsukov, Han Kyu Lee +9
Energy loss due to ohmic heating is a major bottleneck limiting down-scaling and speed of nano-electronic devices, and harvesting ohmic heat for signal processing is a major challe…
The role of the internal demagnetizing field in a surface-modulated magnonic crystal
Manuel Langer, Falk Röder, Rodolfo A. Gallardo +9
Magnonic crystals with locally alternating properties and specific periodicities exhibit interesting effects, such as a multitude of different spin-wave states and large band gaps.…
Spin-wave spectra in periodically surface-modulated ferromagnetic thin films
R. A. Gallardo, M. Langer, A. Roldán-Molina +4
This article presents theoretical results for the dynamic response of periodically surface-modulated ferromagnetic thin films. For such system, the role of the periodic dipolar fie…
Enhanced and reduced atom number fluctuations in a BEC splitter
Kenneth Maussang, G. Edward Marti, Tobias Schneider +6
We measure atom number statistics after splitting a gas of ultracold 87Rb atoms in a purely magnetic double-well potential created on an atom chip. Well below the critical temperat…
On the role of shake-off in single-photon double ionization
T. Pattard, T. Schneider, J. M. Rost
The role of shake-off for double ionization of atoms by a single photon with finite energy has become the subject of debate. In this letter, we attempt to clarify the meaning of sh…
Quasiclassical double photoionization from the 2^{1,3}S excited states of helium including shakeoff
A. Emmanouilidou, T. Schneider, J. -M. Rost
We account for the different symmetries of the 2^{1,3}S helium excited states in a quasiclassical description of the knockout mechanism augmented by a quantum shakeoff contribution…
Separation and identification of dominant mechanisms in double photoionization
Tobias Schneider, Peter Leszek Chocian, Jan-Michael Rost
Double photoionization by a single photon is often discussed in terms of two contributing mechanisms, {\it knock-out} (two-step-one) and {\it shake-off} with the latter being a pur…
Intermanifold similarities in partial photoionization cross sections of helium
Tobias Schneider, Chien-Nan Liu, Jan-Michael Rost
Using the eigenchannel R-matrix method we calculate partial photoionization cross sections from the ground state of the helium atom for incident photon energies up to the N=9 manif…
