Paraelectric and spin liquid phases of H-Cat. a Temperature dependences of κ(H) for H-Cat at 0 and 10 T. b A combination of the temperature dependences of the dielectric constant \(\epsilon _{\mathrm{r}}\) (blue, left axis), the thermal conductivity divided by temperature κ/T (red, left axis) and the magnetic susceptibility χ (green, right axis) for H-Cat. The values of χ are taken from ref. 5. The dashed line is an eye guide. The shaded region represents the QPE and QSL phases. c Magnetic field dependence of the thermal conductivity κ(H) normalized by the zero field value [κ(H) − κ(0)]/κ(0) for H-Cat (filled symbols) and EtMe3Sb[Pd(dmit)2]2 (open circles)26
