Abstract The superheating field H s mathvariant="normal">h of the Meissner state is thought to determine theoretical field-limit superconducting accelerator cavities. We inv...

We present infrared absorption studies of solid hydrogen deuteride to pressures as high as 340 GPa (100  GPa=1  Mbar) in a diamond anvil cell and temperatures in the range 5-295 K. Above 198 GPa the HD sample transforms to a mixture of HD, H_{2}, and D_{2}, interpreted as a process of dissociation and recombination. Three new phase lines are observed, two of which differ remarkably from those o...

we study a new class of $h_v$-structures called fundamentally very thin. this is an extension of the well known class of the very thin hyperstructures. we present applications of these hyperstructures.

We study stability of the Dynamical Fixed Points (DFPs) cascading gauge theory at strong coupling in de Sitter space-time. compute spectra perturbative fluctuations and identify stable/unstable DFPs, characterized by ratio scale $\Lambda$ Hubble constant $H$ background discover a new phenomenon spectrum gravitational non-conformal holographic model: distinct branches for $H\gg \Lambda$ coalesce...

We consider $$(1+8)$$ - and $$(1+10)$$ -dimensional Einstein–Gauss–Bonnet models with a cosmological constant. Some new examples of exact solutions are obtained, governed by three non-coinciding constant Hubble-like parameters $$H\neq 0$$ , $$h_{1}$$ $$h_{2}$$ obeying the condition $$mH+k_{1}h_{1}+k_{2}h_{2}\neq corresponding to factor spaces dimensions $$m\geqslant 3$$ $$k_{1}>1$$ $$k_{2}\geqs...

We investigate the coronal magnetic energy and helicity budgets of ten solar ARs, around times large flares. In particular, we are interested in a possible relation derived quantities to particular type flares that AR produces, i.e., whether they associated with CME or confined. Using an optimization approach, employ time series 3D nonlinear force-free field models covering span several hours o...
