    "abstract": "For Rayleigh-Benard convection in a square cell with a fluid of Prandtl\nnumber one, we report experimental results on the transition between a\nstationary pattern of ideal straight rolls (ISR) and the spatiotemporal chaotic\nstate of spiral defect chaos (SDC). In contrast to experiments in circular\ngeometries, we found ISR states below a particular value of the control\nparameter and SDC states above this value. By characterizing the pattern with a\nglobal measure, the pattern entropy, we found that the transition from SDC to\nISR showed similarities to phase transitions in equilibrium finite-size\nsystems.",
