论文摘要
对于横向场中的反平方远程铁磁ising链，对于横向场的几个值，可获得浮动kosterlitz的热相边界，从而获得量子临界点。经典模型中的尖锐域壁越来越多地被横向场涂抹，这证明了特定热量中非普遍颠簸的明显拓宽。讨论了有限大小模拟中KT临界缩放的可辨认性。
For the inverse square long-range ferromagnetic Ising chain in a transverse field, the thermal phase boundary of the floating Kosterlitz-Thouless phase is obtained for several values of the transverse field down to the quantum critical point. The sharp domain walls in the classical model are increasingly smeared out by the transverse field, which is evidenced by a pronounced broadening of the non-universal bump in the specific heat. The discernability of KT critical scaling in finite-size simulations is discussed.
