      abstract     = {We consider a long, semiflexible polymer with persistence
                      length P and contour length L fluctuating in a narrow
                      cylindrical channel of diameter D. In the regime D < P < L
                      the free energy of confinement Delta F and the length of the
                      channel R-parallel to occupied by the polymer are given by
                      Odijk's relations Delta F/R-parallel
                      to=A(o)k(B)TP(-1/3)D(-2/3) and R-parallel
                      to=L[1-alpha(o)(D/P)(2/3)], where A(o) and alpha(o) are
                      dimensionless amplitudes. Using a simulation algorithm
                      inspired by the pruned enriched Rosenbluth method, which
                      yields results for very long polymers, we determine A(o) and
                      alpha(o) and the analogous amplitudes for a channel with a
                      rectangular cross section. For a semiflexible polymer
                      confined to the surface of a cylinder, the corresponding
                      amplitudes are derived with an exact analytic approach. The
                      results are relevant for interpreting experiments on
                      biopolymers in microchannels or microfluidic devices.},
