We perform an analysis of the behaviour of the electroweak phase transition in the Minimal Supersymmetric Standard Model, in the presence of light stops. We show that, in previously unexplored regions of parameter space, the order parameter v(T c)/T c can become significantly larger than one, for values of the Higgs and supersymmetric particle masses consistent with the present experimental bou...

We suggest that the current acceleration of the universe may be explained by the vacuum energy of a hidden sector which is stuck in a state of equilibrium between phases. The phases are associated to a late-time first-order phase transition, where phase coexistence originates at a temperature Tc ∼ 10−3eV and lasts indefinitely. During phase coexistence, the energy density has an effective cosmo...

We experimentally show that the magnetocaloric properties of molecule-based Prussian blue analogues can be adjusted by controlling during the synthesis the amount of intrinsic vacancies. For CsxNi II 4 [Cr (CN)6](8+x)/3, we find indeed that the ferromagnetic phase transition induces significantly large magnetic entropy changes, whose maxima shift from∼ 68 K to∼ 95 K by varying the number of [Cr...

We discuss for tetrahedratic phases a number of cross-coupling terms not considered before and we analyse their macroscopic physical consequences. In particular we show that if a tetrahedratic phase is acted on by an electric field that is perpendicular to a temperature gradient, an electric current perpendicular to both forces results. We also demonstrate that spatial variations of the tetrahe...

A combination of static and dynamic laser light scattering has revealed that at temperatures higher than ,33 ±C a linear poly(N-isopropylacrylamide) chain grafted with poly(ethylene oxide) (PNIPAMg-PEO) in water can undergo a “coil-to-globule” transition to form a stable single chain core-shell nanostructure with the collapsed PNIPAM chain backbone as the hydrophobic core and the grafted PEO br...

In this study, the nanostructures and thermophysical properties (thermal conductivity, viscosity, and specific heat) of one new type of nanostructured heat transfer fluid, water/polyalphaolefin nanoemulsion fluid, are investigated. The water/ polyalphaolefin nanoemulsion fluids are thermodynamically stable containing dispersed water nanodroplets formed by self-assembly. It has been found that t...

Time crystals are an eagerly sought phase of matter with broken time-translation symmetry. Quantum time discretely symmetry have been demonstrated in trapped ions, atoms and spins while continuously has observed atomic condensate inside optical cavity. Here we report that a classical metamaterial nanostructure, two-dimensional array plasmonic metamolecules supported on flexible nanowires, can b...

The anomalous scaling in the Ginzburg-Landau model for the superconducting phase transition is studied. It is argued that the negative sign of the η exponent is a consequence of a special singular behavior in momentum space. The negative sign of η comes from the divergence of the critical correlation function at finite distances. This behavior is related to the existence of a firstorder transit...
