Robust scenario for the generation of non-equilibrium topological fluctuation states
Kathinka Gerlinger, Rein Liefferink, Michael Schneider +12
The recently discovered topological fluctuation state provides a fascinating new perspective on the ultrafast emergence of topology in condensed matter systems. However, rather lit…
Extreme ultraviolet transient gratings: A tool for nanoscale photoacoustics
L. Foglia, R. Mincigrucci, A. A. Maznev +23
Collective lattice dynamics determine essential aspects of condensed matter, such as elastic and thermal properties. These exhibit strong dependence on the length-scale, reflecting…
High energy-resolution transient ghost absorption spectroscopy
Alok Kumar Tripathi, Yishai Klein, Edward Strizhevsky +10
We demonstrate the measurement of ultrafast dynamics using ghost spectroscopy and a pump-probe approach with an optical pump and a short-wavelength radiation probe. The ghost spect…
Ultrafast amplification and non-linear magneto-elastic coupling of coherent magnon modes in an antiferromagnet
D. Bossini, M. Pancaldi, L. Soumah +6
We investigate the role of domain walls in the ultrafast magnon dynamics of an antiferromagnetic NiO single crystal in a pump-probe experiment with variable pump photon energy. Ana…
Chiral switching and dynamic barrier reductions in artificial square ice
Naëmi Leo, Matteo Pancaldi, Sabri Koraltan +10
Collective dynamics in lithographically-defined artificial spin ices offer profound insights into emergent correlations and phase transitions of geometrically-frustrated Ising spin…
Dependence of energy barrier reduction on collective excitations in square artificial spin ice: A comprehensive comparison of simulation techniques
Sabri Koraltan, Matteo Pancaldi, Naëmi Leo +9
We perform micromagnetic simulations to study the switching barriers in square artificial spin ice systems consisting of elongated single domain magnetic islands arranged on a squa…
