Typed Component Algebras for Simulated Annealing and Markov-Chain Monte Carlo
Rohit Goswami, Ruhila Goswami, Amrita Goswami +3
Simulated annealing (SA) and fixed-temperature Markov-chain Monte Carlo (MCMC) run the same Metropolis-Hastings kernel over a tempered objective, but the variants appear as separat…
ChemFit: A framework for automated high-dimensional model parameter optimization
Moritz Sallermann, Amrita Goswami, Rosana Collepardo-Guevara +4
The parameterization of simulation-based models is a central yet laborious task in computational chemistry and physics, often driven by human intuition and manual iteration. Automa…
Linked skyrmions in shifted magnetic bilayer
Sumit Ghosh, Hiroshi Katsumoto, Gustav Bihlmayer +6
Magnetic solitons have recently attracted significant attention due to their intricate physical properties and potential applications in information processing. The majority of the…
Time Reversible Integration of the Landau-Lifshitz-Gilbert Equation
Moritz Sallermann, Thorsteinn Freygardsson, Sergei Egorov +3
A method for time-reversible numerical integration of the deterministic Landau-Lifshitz Gilbert equation by means of a second order Suzuki-Trotter decomposition is presented and te…
Flowy: High performance probabilistic lava emplacement prediction
Moritz Sallermann, Amrita Goswami, Alejandro Peña-Torres +1
Lava emplacement is a complex physical phenomenon, affected by several factors. These include, but are not limited to features of the terrain, the lava settling process, the effusi…
Identification of mechanisms of magnetic transitions using an efficient method for converging on first order saddle points
Hendrik Schrautzer, Moritz Sallermann, Pavel F. Bessarab +1
A method for locating first order saddle points on the energy surface of a magnetic system is described and several applications presented where the mechanism of various magnetic t…
