An HPC Approach to Accelerate Tensor Decompositions
Markus Hellgren, Erna Begovic Kovac, Hans O. Karlsson +1
Quantum systems grow in complexity so rapidly that even modest models become difficult to simulate, creating a strong need for methods that can handle high-dimensional data, also k…
How Do Methyl Groups Enhance the Triplet Chemiexcitation Yield of Dioxetane?
Morgane Vacher, Pooria Farahani, Alessio Valentini +4
Chemiluminescence is the emission of light as a result of a nonadiabatic chemical reaction. The present work is concerned with understanding the yield of chemiluminescence, in part…
Dynamical Insights into the Decomposition of 1,2-Dioxetane
Morgane Vacher, Anders Brakestad, Hans O. Karlsson +2
Chemiluminescence in 1,2-dioxetane occurs through a thermally activated decomposition reaction into two formaldehyde molecules. Both ground-state and nonadiabatic dynamics (includi…
Wave Packet Simulations of Antiproton Scattering on Molecular Hydrogen
Henrik Stegeby, Markus Kowalewski, Konrad Piszczatowski +1
The problem of antiproton scattering on the molecular Hydrogen is investigated by means of wave packet dynamics. The electronically potential energy surfaces of the antiproton H2 s…
Variational calculations for the hydrogen-antihydrogen system with a mass-scaled Born-Oppenheimer potential
Henrik Stegeby, Konrad Piszczatowski, Hans O Karlsson +2
The problem of proton-antiproton motion in the -- system is investigated by means of the variational method. We introduce a modified nuclear interaction thr…
Quantum interference structures in trapped ion dynamics beyond the Lamb-Dicke and rotating wave approximations
Dong Wang, Tony Hansson, Asa Larson +2
We apply wave packet methods to study an ion-trap system in the strong excitation regime imposing neither the rotating wave nor the Lamb-Dicke approximations. By this approach we s…
