I am currently trying to find labs and groups that are exploring a certain topic. The background is that I'm trying to apply to grad school and looking for labs that are suitable for my interest. The problem is that since I'm fairly new to physics research, I'm having difficulty phrasing my questions specifically enough to find what I'm looking for. I was wondering if it's appropriate to enquire about this on physics stack exchange or if it's not? I'd be asking things akin to "how do I find labs that are approaching this question?", "what are better ways to phrase this [conceptual question] as a research question?", and "how to find labs who are researching [insert]?"?
