我们认为，fe的长程库仑能将孤立的（N，N）扶手碳纳米管转化为强重整化的卢廷格液体。在高温下，我们发现了束缚相互作用和杂质对电阻率的异常温度依赖，以及类似的幂律依赖于态的局部隧道密度。在低温下，纳米管表现出自旋电荷；分离，在状态的离散隧道密度（我们给出了解析形式）中作为额外的能量尺度可见，标志着与正统的库仑封锁理论的背离。
We argue that long-range Coulomb for fes convert an isolated (N,N) armchair carbon nanotube into a strongly renormalized Luttinger liquid. At high temperatures, we find anomalous temperature dependences for tie interaction and impurity contributions to the resistivity, and similar power-law dependences for the local tunneling density of states. At low temperatures, the nanotube exhibits spin-charge; separation, visible as an extra energy scale in the discrete tunneling density of states (for which we give an analytic form), signaling a departure from the orthodox theory of Coulomb blockade.
