    "abstract": "The shape of semiflexible polymer rings is studied over their whole range of\nflexibility. Investigating the joint distribution of asphericity and nature of\nasphericity as well as their respective averages we find two distinct shape\nregimes depending on the flexibility of the polymer. For small perimeter to\npersistence length the fluctuating rings exhibit only planar, elliptical\nconfigurations. At higher flexibilities three dimensional, crumpled structures\narise. Analytic calculations for tight polymer rings confirm an elliptical\nshape in the stiff regime.",
