The laser field is described as a constant field \({{\bf{E}}}(t)=-\hat{{{\bf{x}}}{E}_{0}\), referring to the adiabatic regime. According to the Dyson equation, the solution of the Schrödinger equation can be expressed via the exact time-evolution operator (TEO)33: $$U(t,...
However, new drug discovery is a tremendously challenging, time-consuming and expensive task. The main challenges are to explore drug target proteins (receptors) responsible for the diseases and drug agents (small molecules) that can reduce the diseases by the interaction with the target proteins. ...
This corresponds to the factorisation of internal level correlations, \(\langle {\hat{\sigma }}_{i}^{\alpha }{\hat{\sigma }}_{j}^{\beta }\rangle \approx \langle {\hat{\sigma }}_{i}^{\alpha }\rangle \langle {\hat{\sigma }}_{j}^{\beta }\rangle\) (α≠ β), since we...
