SpinDynamica 3.3.2

SpinDynamica 3.3.2 has been released. Eigenbasis now takes TargetBasis as an optional argument. The calculated Eigenbasis and TargetBasis are aligned as closely as possible. This is useful for controlling the ordering of the basis kets in the Eigenbasis and also for adiabatic calculations. Some bug fixes and speed improvements to the basis construction of spins with …

SpinDynamica 3.3.1

SpinDynamica 3.3.1 has been released. –The recent SpinDynamica update introduced some problems with WignerD. This bug has been fixed now. –The functionality of CorrelatedEigensystems has been extended. CorrelatedEigensystems now supports Liouvillians and arbitrary sets of matrices. –The usage messages for CorrelatedEigensystems and Adiabatic routines were not informative enough. The usage messages have been expanded and explicit examples are now given. …

SpinDynamica 3.2.1

SpinDynamica 3.2.1 has been released. -SpinDynamica now allows for a user specified level of error-trapping via UserLevel. A high degeree of error trapping tends to slow down execution speed. UserLevel may be used to reduce the amount of error trapping leading to improved execution speed for some routines. -SpinDynamica now contains the new routine MaximizeTransformationAmplitude. MaximizeTransformationAmplitude may be …

SpinDynamica 3.1.0 with a couple of new features!

SpinDynamica 3.1.0 has been released. A couple of new features have been added to the new version of SpinDynamica. -SpinDynamica now supports dedicated routines for the analysis of adiabatic transformations: 1. CorrelatedEigensystems – This new routine allows the analysis of the correlation between spin-states and the corresponding change in eigenvalues as a function of the adiabatic …

SpinDynamica administration

Welcome to Christian Bengs who has taken over administration over this site. Christian has already done a lot of excellent coding as part of our new release of SpinDynamica (v3.0.1) and our first SpinDynamica publication. It’s great to have his help! So many thanks to Christian, and enjoy the new version of SpinDynamica! Malcolm
