利用最近的估计，由我们中的一个，各向同性铁电体转变的临界温度的高密度偶极硬球，我们进行了新的Monte Carlo模拟在这些估计的附近，并应用直方图重新加权方法，以获得细化值的临界温度从交叉的四阶累积量为不同的系统尺寸。铁电线被确定在密度范围rho*=0.80-0.95，和柱状有序的发病被定位。
Taking advantage of recent estimates, by one of us, of the critical temperature of the isotropic-ferroelectric transition of high density dipolar hard spheres, we performed new Monte Carlo simulations in the close vicinity of these estimates and applied histogram reweighting methods to obtain refined values of the critical temperatures from the crossing of the fourth-order cumulant for different system sizes. The ferroelectric line is determined in the density range rho*=0.80-0.95, and the onset of columnar ordering is located.
