| 中文摘要 | The thermodynamics and transport properties of strong-rail ladder systems are investigated by means of Greens function theory. It is shown that the magnetic behavior clearly Manifests a typical antiferromagnetism with gapped or gapless low lying excitations, which is in agreement with the experimental results. In addition, the temperature-field-induced phase diagram is explored, and we demonstrate a Luttinger liquid behavior in the window h(c) (marking the ending of the M=0 plateau) < h < h(s) (saturation magnetic field) within a narrow range of temperature. The spin liquid phase is uncovered for h < h, upon cooling down to zero temperature. It is also shown that the rung entanglement entropy is a good indicator for detecting the field-driven quantum criticality. Meanwhile, the magnetic sus, ceptibility, the specific heat, and the thermal (spin) Drude weights are calculated to characterize the plentiful quantum phases, in which the thermal insulating and conducting behaviors can be controlled by magnetic fields. |
