  abstract = {We investigate a system consisting of two like-charged infinitely
	long rods and neutralizing counterions at low temperatures, using
	both analytic theory and simulations. With some reasonable approximations
	we can analytically solve for several ground-state structures of
	the model, starting with states where all counterions are lined up
	in the gap between the rods, over planar configurations, where the
	counterions are divided up into a fraction which resides between
	the rods, and counterions which are located on the outer surfaces,
	up to configurations which cover the full rod surfaces. Using parallel
	tempering simulations, we are able to study the system over a wide
	range of temperatures. At low temperatures we find good agreement
	with our T = 0 results. At higher temperatures, the strong coupling
	(SC) theory delivers qualitatively better results. We furthermore
	demonstrate that for the SC theory and our ground-state approximations
	to yield quantitative agreement, three parameters are required to
	be large, the strong-coupling parameter \Xi , the Rouzina-Bloomfield
	parameter, and the ratio of the average distance of the counterions
	to the radius of the rods. In the case of the latter ratio being
	small, our T = 0 results show better agreement with the simulation
	data at very low temperatures.},
