Membranai, pagamintai iš medžiagos, kurios fizinės savybės aprašomos deformacijos energijos funkcija W tūrio vienetui, deformacijos energijos funkcija Φ membranos vidurinio paviršiaus ploto vienetui gaunama integruojant funkciją W pagal membranos storį. (Nagrinėjama deformacijos energijos funkcija W neturi nustatytų apribojimų ir yra leidžiamos bet kokio dydžio deformacijos.) Funkcijos Φ tiksli išraiška yra išvesta skersai izotropinei medžiagai, kai izotropijos ašis sutampa su membranos nedeformuoto vidurinio paviršiaus normale. Parodoma, kad skersai izotropinei medžiagai gauta dvimatė membranos darbą apibūdinanti funkcija yra izotropinė ir išsamiai ištirta gautų fizinių priklausomybių struktūra. Tokios fizinės priklausomybės yra išvestos keturiems kontinuumo mechanikoje dažnai nagrinėjamų medžiagų tipams.

We prove that a recently derived correlation equality between conserved charges and their associated conserved currents for quantum systems far from equilibrium [O.A. Castro-Alvaredo, B. Doyon, and T. Yoshimura, Phys. Rev. X 6, 041065 (2016)], is valid under more general conditions than assumed so far. Similar correlation identities, which in generalized Gibbs ensembles give rise to a current symmetry somewhat reminiscent of the Onsager relations, turn out to hold also in the absence of translation invariance, for lattice models, and in any space dimension, and to imply a symmetry of the non-equilibrium linear response functions.

AbstractThe equation of state of fluid hydrogen, helium, and their mixtures is determined within fluid variational theory. Reactions between the constituents such as dissociation and ionization are considered. Results are given for densities and temperatures relevant for the interior of giant planets. Furthermore, the electrical conductivity is determined within linear response theory. Comparison is performed with available experiments and other theoretical work.
