Temperature driven spin incoherence and criticality in the Luttinger liquid phase of an ideal spin ladder material

Abstract: We propose an experiment on the low energy spectrometer LET to study temperature effects on the Luttinger liquid (LL) phase on the spin ladder geometry. The spin ladder material (HPIP)2CuCl4 (BPCC), is a near ideal realisation of the a spin ladder, with exchanges which enable all excitations in the entire phase diagram to be studied. Firstly we will use the exceptional resolution of LET with the 9T magnet and dilution to finish studying the field dependence of the excitations of the LL phase. Recent theoretical developments have highlighted the effect of temperature on spin/charge coherence in the LL phase. Full measurements of this phase have never been performed and can lead to a greater understanding of its universality class. Finally we propose to study critical scaling laws at both quantum critical points of the spin ladder phase diagram, which has never before been attempted.
