Winter internship for Indian students (computational physics) I am 3 year BS MS dual degree student (at Indian Institute of Science Education and Research) in Physics and I want to learn computational skills for my future career needs because we don't have computational physics course till the 8th semester.

Do we have any provision of winter internship in India?
Yes!

Keep in mind though that most such internships at places like IIT, IISc, ISI, TIFR etc. are likely to be unpaid and you will most probably have to bear costs on your own.

The way to getting them is to email appropriate professors that you like and then ask them if you could, given their availability, work with them over winter.

I do not know if there are industrial research internships in India over winter. Most of them seem to be restricted to summer.
