2.0.0
2018-04-27
- The app has been rewritten to simulate spin dynamics based on the full density matrix formalism. This makes it possible to simulate not only ideal pulses but also the effects of resonance offsets and couplings during pulses. In addition, strong coupling effects can be taken into account, both during delays and pulses.
- The density operator, as well as additional operators such as the Hamiltonian, effective Hamiltonian, and the effective propagator of a pulse sequence can be displayed
(a) graphically using the DROPS representation, (b) in terms of linear combinations of Cartesian product operators or other useful basis operators, and (c) in matrix form.
- In addition to the simplified and intuitive pulse sequences from SpinDrops 1.0, an alternative sequence language for advanced users is supported in SpinDrops 2.0, which makes it possible to copy and paste pulse sequences from the spectrometer, to define experiments directly in terms of Hamiltonians or propagators and to implement shaped pulses.
- Multiple workspaces let the user easily switch between multiple projects, e.g. for learning, teaching or research.
- Multiple concurrent phase cycle view demonstrates the mechanism of phase cycling.
The SpinDrops project has migrated to the Glaser Group at Technical University of Munich (TUM).
1.2.2
