Main interest: To understand the description of open QM systems. To use the Stochastic Liouville Equation in Theoretical and Physical Chemistry describing relaxation in NMR-spectroscopy.
Per-Olof Westlund: Analysis of disentanglement in open QM systems and the use of SLE in chemistry.
The Stochastic Liouville Equation SLE: the starting point of choice for analysis of open QM systems in the semi-classical approach.
SLE treats the impact of a classical system on a QM subsystem when studied by different spectroscopic methods such as NMR ,EPR or fluorescence.
Below three ongoing projects 2020
1.The interpretation of the famous Stern-Gerlach experiment and its use in the Einstein-Podolsky-Rosen(EPR) paradox reformulated by D. Bohm.
My understanding and conclusion about this thought experiment is based on our four papers[2012,2013,2017,2019] together with H. Wennerström).
The spin states of particle A or B in the EPR-B thought experiment cannot be measured by a Stern-Gerlach device as long as the two spin particles is forming a singlet state. Both A and B will go straight through the S-G device [2019]. On the other hand if we assume that for instance particle A is passing through a S-G device in either a spin up or spin down path, the singlet state must have been destroyed. A single spin particle passing through a S-G magnet is taking spin "up" path or spin "down" path due to the effect of other degrees of freedom(electron spin-translational)[2012,2017], and these coupling cause relaxation and that a spin particle ends up in either "up" or "down" position (no collapse of the wavefunction but spin relaxation)[2012]The disentanglement (killing the singlet state) we think can be due to the field gradients outside the magnet which connect to the translational degrees of freedom of particle A or B. Thus "no spooky force at long distance exists" and Bells theorem is not violated in this EPR-B thought experiment [2013,2019].
2.The motion of water( or biomolecules) in micro-heterogenous systems and its influence on their NMR line-shape and T1 relaxation.
3. A meta-theory of Natural Science and the Ethics of Natural Science.
A. What is natural science and what is not depends on a decision by the scientific community and the editors of scientifc journals. Consequently therie is no "objective" criterion (however, still not subjective) what is science and what is not.
B. One should formulate an ethical guide which is helpful in evaluating scientist productivity. The publishing norms so far published ignore to evaluate the individual contributions in multi author papers. This leads to unethical publishing practices .
