Painting Taylor vortices with cellulose nanocrystals: supercritical spectral dynamics
Reza Ghanbari, Sajjad Pashazadeh, Kesavan Sekar +5
We study the flow stability and spatio-temporal spectral dynamics of cellulose nanocrystal (CNC) suspensions in a custom Taylor-Couette flow cell using the intrinsic shear induced…
Heat-conserving three-temperature model for ultrafast demagnetization of 3d ferromagnets
M. Pankratova, I. P. Miranda, D. Thonig +6
We study the ultrafast magnetization dynamics of bcc Fe and fcc Co using the recently suggested heat-conserving three-temperature model (HC3TM), together with atomistic spin- and l…
Unraveling the connection between high-order magnetic interactions and local-to-global spin Hamiltonian in non-collinear magnetic dimers
Ramon Cardias, Jhonatan dos Santos Silva, Anders Bergman +7
A spin Hamiltonian, which characterizes interatomic interactions between spin moments, is highly valuable in predicting and comprehending the magnetic properties of materials. A de…
Metaheuristic conditional neural network for harvesting skyrmionic metastable states
Qichen Xu, I. P. Miranda, Manuel Pereiro +8
We present a metaheuristic conditional neural-network-based method aimed at identifying physically interesting metastable states in a potential energy surface of high rugosity. To…
