Different permissions on item creation

Within SP 2013, is it possible to do the following in terms of permissions :

Two different AD groups : Admins & Users. With only one list.

• When Users access this list, they can add/modify only item that are related to themselves (depending on a people field).


• When Admins access this list, they can add/modify every items they wish in the list.

I think this has already been asked, but I can't find it.

TIA
