I am a fourth-year physics major. Although I have decided to pursue a PhD in experimental physics, I am still interested in using simulations to tackle theoretical problems with toy models (e.g., tight-binding , XY model for BKT ). So, is it possible to do amateur theoretical research in the age of AI? I am not aiming to publish papers—I just want to satisfy my curiosity about frontier issues in condensed matter physics and make sure my understanding and work are correct.
