The almost frictionless transport of the very-high temperature amorphous matter which resembles the color glass condensate (possibly having much of their origin in the RHIC heavy ion collisions) in a confined annular tube with transversely corrugations is investigated by using the verified transition-rate model and boundary perturbation method. We found that for certain activation volume and energy there exist possible frictionless states which might be associated with the perfect fluid formation during the early expansion stage in RHIC Au+Au collisions. We also address the possible similar scenario in LHC Pb+Pb collisions considering the possible perfect fluid formation in ultra-high temperature transport of amorphous matter.

We investigate the possible frictionless transport of many composite (condensed) fermions at room temperature regime along an annular tube with transversely wavy-corrugations by using the verified transition-rate model and boundary perturbation appro ach. We found that for certain activation volume and energy there exist possible frictionless states at room temperature regime.

The gravity-driven flow along an annular topological defect (string) with transversely corrugations is investigated by using the verified transition-rate model and boundary perturbation method. We found that for certain activation volume and energy t here exists possible frictionless states which might be associated with the missing momentum of inertia or dark matter.
We have mooted a new charged scalar field theory using a doublet of the Galileon scalar field instead of the usual Klein Gordon real scalar fields. Our model for the charged scalar field have a few remarkable properties like Poincare invariance , Abe lian gauge symmetry and shift symmetries. The existence of two independent gauge symmetries is a welcome news for fracton physics.Whereas phase rotation in $phi$ space leads to the conservation of electric charge , the additional symmetries correspond to the conservation of a scalar charge and a vector charge. The system is shown to resemble matter in the fracton phase. Consequently, the results in this letter have immense possibilities in fracton physics.
Magnetization M(T,H) measurements performed on thoroughly characterized commercial amorphous carbon powder doped with sulfur (AC-S), revealed the occurrence of an inhomogeneous superconductivity (SC) below T_c = 38 K. The constructed magnetic field-t emperature (H-T) phase diagram resembles that of type-II superconductors. However, AC-S demonstrates a number of anomalies. In particular, we observed (1) a non-monotonic behavior of the lower critical field H_c1(T); (2) a pronounced positive curvature of the upper critical field boundary that we associated with the flux lattice melting line Hm(T); (3) a spontaneous ferromagnetic-like magnetization M0 coexisting with SC. Based on the analysis of experimental results we propose a nonstandard SC state in AC-S.
Neutrino Physics is now entering precision era and neutrino-nucleon cross sections are an im- portant ingredient in all neutrino oscillation experiments. Specially, precise knowledge of neutrino- nucleon cross sections in Ultra High Energy (UHE) regi me (TeV-PeV) is becoming more important now, as several experiments worldwide are going to observe processes involving such UHE neutrinos. In this work, we present new results on neutrino-nucleon cross-sections in this UHE regime, using QCD.
