(a) Logarithm of the density of states (DOS) g(E) of the protein inside the confining potential V1(r) and for different values of Rc (15 Å, 20 Å, 25 Å) as well as for the bulk case. One notices the remarkable decrease of the DOS for decreasing Rc. (b) Specific heat for the bulk case and for confining potentials with radii 15 Å, 20 Å, and 25 Å. Tf = 321 K is the transition temperature in the bulk case. Tf increases as the radius Rc decreases. The confining potential in panels a and b is purely repulsive.
