Description de proposition

The first step to simulate the dynamics of spin systems is to construct the basic elements of Nuclear Magnetic Resonance (NMR) including the Liouvillian matrix, relaxation matrix, pulse matrix and equilibrium state. It is easy to deal with single spin systems, but there are more challenges to do coupled-spin systems. The computer algebra software provides the feasibility to build these elements for n-spin systems. Applying these elements, we can simulate and analyze the whole process of NMR experiments of more complex spin systems and pulse sequences in symbolic or numerical ways. In this talk, we will illustrate the computation of some experiments such as spin echo, steady state, INADEQUATE. We may also show how to efficiently compute the objective function, its first-order and second-order derivatives in the optimal pulse design.

Abstract:
The first step to simulate the dynamics of spin systems is to construct the basic elements of Nuclear Magnetic Resonance (NMR) including the Liouvillian matrix, relaxation matrix, pulse matrix and equilibrium state. It is easy to deal with single spin systems, but there are more challenges to do coupled-spin systems. The computer algebra software provides the feasibility to build these elements for n-spin systems. Applying these elements, we can simulate and analyze the whole process of NMR experiments of more complex spin systems and pulse sequences in symbolic or numerical ways. In this talk, we will illustrate the computation of some experiments such as spin echo, steady state, INADEQUATE. We may also show how to efficiently compute the objective function, its first-order and second-order derivatives in the optimal pulse design.
