      abstract     = {Disklike molecules with aromatic cores spontaneously stack
                      up in linear columns with high, one-dimensional charge
                      carrier mobilities along the columnar axes, making them
                      prominent model systems for functional, self-organized
                      matter. We show by high-resolution optical birefringence and
                      synchrotron-based x-ray diffraction that confining a
                      thermotropic discotic liquid crystal in cylindrical
                      nanopores induces a quantized formation of annular layers
                      consisting of concentric circular bent columns, unknown in
                      the bulk state. Starting from the walls this ring
                      self-assembly propagates layer by layer towards the pore
                      center in the supercooled domain of the bulk
                      isotropic-columnar transition and thus allows one to switch
                      on and off reversibly single, nanosized rings through small
                      temperature variations. By establishing a Gibbs free energy
                      phase diagram we trace the phase transition quantization to
                      the discreteness of the layers’ excess bend deformation
                      energies in comparison to the thermal energy, even for this
                      near room-temperature system. Monte Carlo simulations
                      yielding spatially resolved nematic order parameters,
                      density maps, and bond-orientational order parameters
                      corroborate the universality and robustness of the
                      confinement-induced columnar ring formation as well as its
                      quantized nature.},
