Is computational physics a PhD area of study?

Click For Summary

Discussion Overview

The discussion revolves around the classification of computational physics as a potential area of study for a PhD. Participants explore whether it is a distinct field or a subset of established areas such as high-energy physics (hep) or condensed matter physics, and debate its classification as theoretical or experimental.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants question if computational physics is a standalone PhD area or merely a branch of other physics disciplines.
  • There is a suggestion that the classification of computational physics as theoretical or experimental depends on the specific activities involved, such as running simulations versus developing numerical methods.
  • One participant notes that most computational work at universities is categorized under theoretical physics, emphasizing that computational physics serves as a tool across various branches rather than being a distinct field.
  • A PhD student mentions spending a significant portion of their time on numerical simulations within the realm of theoretical physics, specifically in condensed matter physics.
  • Another participant points out that some universities have dedicated computational physics research groups, indicating an institutional recognition of the field.

Areas of Agreement / Disagreement

Participants express differing views on whether computational physics is a separate area of study or a tool used within established fields. There is no consensus on its classification as theoretical or experimental, with opinions varying based on individual experiences and interpretations.

Contextual Notes

The discussion highlights the ambiguity surrounding the definition and classification of computational physics, with participants acknowledging the dependence on specific research activities and institutional structures.

If someone wanted to go into computational physics, would that be the PhD area of study, or is it just a branch of the better known areas, like hep, condensed matter, etc. Also is it considered theoretical or experimental? (I would assume experimental).

Thanks!

It is computational physics xD...

However, if you really want to classify it as either experimental or theoretical physics, I would say it depends on what you actually do...

If you are just running a code and focussing in the analysis of the results, than it is more experimental. But if you are developing numerical methods I would say it is more a theoretical branch.
 
Most of the computational work done by faculty at universities that I've seen is considered in the theoretical department.

But you don't just do "computational physics." Computational physics is a tool used for physics research just the same as conducting experiments or using pen & paper. It is a more practical way to simulate processes and reactions that would be expensive and/or impossible to do physically. It exists in every branch of physics, it doesn't really have it's own branch. So there is computational materials physics, computational astrophysics, computational plasma physics, etc.

My point is that computational physics isn't itself an actual thing, but a tool applied to the various branches of physics.
 
My two cents... I nominally am a PhD student in theoretical physics. In reality, I spend about 70% of my time and effort doing numerical simulations versus about 30% of the time doing traditional, pen and paper theory. I find this balance to be extremely satisfying, personally.

My field, on the other hand, is Condensed Matter Physics.
 
There are departments, and I think UCF or USF (in Florida) are one of them, where they have an explicitly-titled "computational physics" research group.
