Should I include visiting students in my CV I am currently a Post-Doc in the field of physics. During the last years, a number of students from different universities (from across the world) were visiting me for short (1 week) or long (3 months) periods. 

Since they came to specifically work with me, I was supervising them during that time and now I am wondering if I should include them somehow in my CV (e.g. in the section Teaching, listed as visiting students or something similar) ?
Just to make it transparent for future readers that your question got a (preliminary) answer suggestion: 
If you directly collaborated with them, I would put them in the cv and mention what you did (together). This helps the visiting student, because his/her name is mentioned in relation to you. It also helps you to keep track of your collaboration project and to show others (in future applications) what you did in the last years. As you said, being in contact and supervising students for a certain time can also be seen as a form of teaching. Perhaps, later you will publish with some of them papers and then, it is interesting to know that your co-author(s) might have been a former visiting student Otherwise, if you just mention their names in the CV, it might not be clear for a reader of your CV what this 'visiting student list' exactly means.
