The physical meaning of the "boost-rotation symmetric" solutions within the general interpretation of Einstein's theory of gravitation

S. Antoci, D. -E. Liebscher, L. Mihich

The answer to the question, what physical meaning should be attributed to the so-called boost-rotation symmetric exact solutions to the field equations of general relativity, is pr…

The density of very massive evolved galaxies to z~1.7

P. Saracco, M. Longhetti, P. Severgnini +8

We spectroscopically identified 7 massive evolved galaxies with magnitudes 17.8<K<18.4 at 1.3<z<1.7 over an area of ~160 arcmin^2 of the MUNICS survey. Their rest-frame K-band abso…

Upper Critical Fields up to 60T in Dirty Magnesium Diboride Thin Films

C. Ferdeghini, V. Ferrando, C. Tarantini +11

Upper critical fields of several magnesium diboride thin films were measured up to 28 T at the Grenoble High Magnetic Field Laboratory (GHMFL) in Grenoble and up to 60 T at the Lab…

Small Fermi energy, zero point fluctuations and nonadiabaticity in MgB

L. Boeri, E. Cappelluti, L. Pietronero

Small Fermi energy effects are induced in MgB by the low hole doping in the bands which are characterized by a Fermi energy eV. We show that, due to t…

Vacuum field correlations and three-body Casimir-Polder potential with one excited atom

R. Passante, F. Persico, L. Rizzuto

The three-body Casimir-Polder potential between one excited and two ground-state atoms is evaluated. A physical model based on the dressed field correlations of vacuum fluctuations…

Dynamics of relativistic solitons

Daniela Farina, Sergei V. Bulanov

Relativistic solitons are self-trapped, finite size, electromagnetic waves of relativistic intensity that propagate without diffraction spreading. They have been predicted theoreti…
