Interacting bloch hamiltonian

Nettetnon-relativistic quadratic Hamiltonian. In Supplemental Ma-terial, we show an equivalent derivation for a general Bloch Hamiltonian Hˆ(k). We focus on external driving fields with few nonzero Fourier components and write A(t) = ω A(ω)ei(ω −iη)t with A(ω) = A∗(−ω). The limit as η → 0 denotes an adiabatic turning on of the ... NettetAbstract. Simulating NMR experiments may appear mysterious and even daunting for those who are new to the field. Yet, broken down into pieces, the process may turn out to be easier than expected. Quite the opposite, it is in fact a powerful and playful means to get insights into the spin dynamics of NMR experiments. In this tutorial paper, we show …
