I was enrolled in a PhD program within an experimental topic (experimental physics), but 6 months in the project I had a talk with my supervisor: I was not satisfied with the lack of theoretical work (at my interview we had decided that there should/would be some).
A few meetings followed, where we concluded that it would not be realistic to do any major theoretical work at all. Together with my supervisor we decided that it was best for me to stop my PhD-program and he encouraged me to enroll for a new one in theoretical physics, such that I didn't waste 3 years of my life doing something I would regret. He wrote a recommendation letter for me and I got accepted into a theoretical program.
Here is my problem: I now have to write a short statement now on why I have discontinued my former topic and started a new one. However, I am worried that it might sound as if I stopped due to conflicts/disagreements with my supervisor, which was not the case at all. Quite the contrary, he was very helpful through the whole process.
Can it be interpreted as such if I write something along the lines of "former project could not accomodate my theoretical ambitions"? How should I tackle this?
