Elementary excitations for right and left handed electrical systems: Thermal-fluctuations comparison

Excitation modes of left handed and right handed electrical circuits are thermodynamically compared. Thermal fluctuations ratio of the internal energy as function of the temperature, number of cells and spatial dimension, are explicitly calculated. Analytically, in the high temperature limit both systems have similar thermal fluctuations. In the regime of low temperatures left handed systems support less thermal noise than right handed. These results are confirmed numerically. By comparison, left handed systems are more efficient as devices of information transmission.
