Sample interview questions: Describe a time when you had to modify or adapt an existing theoretical model to fit experimental data.
Sample answer:
As a theoretical physicist, I have encountered numerous situations where I needed to modify or adapt an existing theoretical model to fit experimental data. One such instance was when I was working on a project related to quantum mechanics and the behavior of particles in a specific system.
In this particular experiment, we were investigating the behavior of electrons in a confined system under the influence of an external magnetic field. The existing theoretical model we had relied on certain assumptions that were not fully applicable to our experimental setup. As a result, the predictions made by the model did not match the experimental data we obtained.
To address this issue, I began by carefully analyzing the experimental data and identifying any patterns or inconsistencies. This allowed me to pinpoint the aspects of the existing theoretical model that needed modification. One crucial aspect was the neglect of certain interactions between the electrons and the external magnetic field.
To adapt the existing theoretical model, I incorporated additional terms into the equations that accounted for these previously overlooked interactions. This modification allowed for a more accurate representation of the experimental data. However, it was not a simple task, as it required a deep understanding of the underlying physical principles and mathematical techniques.
To verify the modified model, I performed furt… Read full answer
