Quantifying non-Markovianity in magnetization dynamics via entropy production rates
Felix Hartmann, Finja Tietjen, R. Matthias Geilhufe +1
Magnetization dynamics is commonly described by the stochastic Landau-Lifshitz-Gilbert (LLG) equation. On picosecond timescales, inertial and open-system extensions of the LLG equa…
Intrinsic non-Markovian magnetisation dynamics
Felix Hartmann, Vivek Unikandanunni, Matias Bargheer +3
Memory effects arise in many complex systems, from protein folding, to the spreading of epidemics and financial decisions. While so-called non-Markovian dynamics is common in large…
Atomistic spin dynamics with quantum colored noise
Fried-Conrad Weber, Felix Hartmann, Matias Bargheer +2
The accurate prediction of temperature-dependent magnetization dynamics is a fundamental challenge in computational magnetism. While Atomistic Spin Dynamics (ASD) simulations have…
Pb transport on Si(111)-(7x7) following tip induced imbalance
Paul Philip Schmidt, Felix Hartmann, Lea Faber +3
Pb on Si(111)-(7x7) shows surprising nucleation and mass transport dynamics at odds with standard theories. To create local imbalances on stable Pb islands we use the tip of a scan…
Anisotropic signatures in the spin-boson model
Felix Hartmann, Stefano Scali, Janet Anders
Thermal equilibrium properties of nanoscale systems deviate from standard macroscopic predictions due to a non-negligible coupling to the environment. For anisotropic three-dimensi…
