Fig. 1. A 2D sketch of the simulation model. Two spherical cavities, a small one with radius R s and a large one with radius R l, are connected by a small hole with diameter D h. The polymer is confined in the two cavities.
Fig. 2. The SCO probability P SCO as a function of R for different N . The radius where P SCO = 0.5 is defined as the critical radius R C. The inset shows the phase diagram for the symmetric twin-cavity system. The red line shows the radius of gyration (R g0) of polymer in free space as a function of N .
Fig. 3. The SCO probability P SCO as a function of the radius of the small cavity R s for different R l (< R C), where N = 60. The radius where P SCO = 0.5 is defined as the critical radius R sC.
Fig. 4. Phase diagram for the asymmetric system, where N = 60. The inset shows the dependence of R sC on R l 9 / 4 N − 3 / 4 N = 40, 60, 80, 100, and 120. The solid black line is guide for eyes.
Fig. 5. The relative probabilities of the whole polymer in the small cavity (P s/P SCO) and in the large cavity (P l/P SCO) in the SCO phase as functions of the radius of the small cavity R s for different R l, where N = 60.
Fig. 6. The equilibrium number (m s) of monomers in the small cavity as a function of R s for different R l (< R C), where N = 60. The inset shows m s/N as a function of (R l/R s)3 for different R l and N . The solid red line is given by Eq. (12 ).
