Analysis of the buildup of spatiotemporal correlations and their bounds outside of the light cone
Nils O. Abeling, Lorenzo Cevolani, Stefan Kehrein
In non-relativistic quantum theories the Lieb-Robinson bound defines an effective light cone with exponentially small tails outside of it. In this work we use it to derive a bound…
Anomalous dynamical phase in quantum spin chains with long-range interactions
Ingo Homrighausen, Nils O. Abeling, Valentin Zauner-Stauber +1
The existence or absence of non-analytic cusps in the Loschmidt-echo return rate is traditionally employed to distinguish between a regular dynamical phase (regular cusps) and a tr…
Quantum Quench Dynamics in the Transverse Field Ising Model at Non-zero Temperatures
Nils O. Abeling, Stefan Kehrein
The recently discovered dynamical phase transition denotes non-analytic behavior in the real time evolution of quantum systems in the thermodynamic limit and has been shown to occu…
Photo-magnonics
Benjamin Lenk, Fabian Garbs, Henning Ulrichs +2
In the framework of magnonics all-optical femtosecond laser experiments are used to study spin waves and their relaxation paths. Magnonic crystal structures based on antidots allow…
Spin-wave modes and band structure of rectangular CoFeB antidot lattices
Benjamin Lenk, Nils Abeling, Jelena Panke +1
We present an investigation of rectangular antidot lattices in a CoFeB film. Magnonic band structures are numerically calculated, and band gaps are predicted which shift in frequen…
