I am an undergrad physics major at a US university. I plan on attending grad school for condensed matter physics, so I've been looking for research opportunities here. There is limited condensed matter research, however, and most of it is done through the materials science/engineering department. Would it be looked down on by physics grad programs if I did my undergrad research with a lab in that department? Or would I be better off doing undergrad research in a different field within the physics department? I'd appreciate any advice.
