First Order Phase

The Mössbauer investigations of V1-xFexO2 with x = 0.024 indicate that Fe enters two cation positions of M2 and M3. At the phase transition the two quadrupole splittings show a discontinuous behavior whereas the isomer shift changes continuously with a crossingover at the M2, M3 transition (Tt′ = 275 K). Generally a first order phase transition is accompanied by a change of the cell volume V and a change of the isomer shift. The observed continuous behavior of the isomer shift points to a first order transition with δV ≠ 0.

Abstract We explore and contrast the capabilities of future colliders to probe the nature of the electro-weak phase transition. We focus on the real singlet scalar field extension of the Standard Model, representing the most minimal, yet most elusive, framework that can enable a strong first-order electro-weak phase transition. By taking into account the theoretical uncertainties and employing the powerful complementarity between gauge and Higgs boson pair channels in the searches for new scalar particles, we find that a 100 TeV proton collider has the potential to confirm or falsify a strong first-order transition. Our results hint towards this occurring relatively early in its lifetime. Furthermore, by extrapolating down to 27 TeV, we find that a lower-energy collider may also probe a large fraction of the parameter space, if not all. Such early discoveries would allow for precise measurements of the new phenomena to be obtained at future colliders and would pave the way to definitively verify whether this is indeed the physical remnant of a scalar field that catalyses a strong first-order transition.

Temperature Susceptibility

The high temperature susceptibility series of the model proposed by Haus and Tanaka (1977) to account for the transition of the orientationally disordered ice VII phase to the orientationally ordered ice VIII phase does not provide evidence for the possible occurrence of a first-order transition, as predicted by the mean field approximation, but gives a second-order transition instead.
