Gravity of a static massless scalar field and a limiting Schwarzschild-like geometry
M. Gaudin, V. Gorini, A. Kamenshchik +2
We study a set of static solutions of the Einstein equations in presence of a massless scalar field and establish their connection to the Kantowski-Sachs cosmological solutions bas…
The spectral approximation of multiplication operators via asymptotic (structured) linear algebra
Stefano Serra Capizzano
multiplication operator on a Hilbert space may be approximated with finite sections by choosing an orthonormal basis of the Hilbert space. Nonzero multiplication operators on …
The host galaxies of low luminosity quasars at high redshift
J. K. Kotilainen, R. Falomo, A. Treves +1
We present VLT/ISAAC near-infrared imaging of the host galaxies of 15 low luminosity quasars at 1 < z < 2. This work complements our studies to trace the cosmological evolution of…
The evolution of Radio Loud Quasar host galaxies: AO observations at z = 3
R. Falomo, J. K. Kotilainen, R. Scarpa +2
We report on ESO--VLT adaptive optics imaging of one radio-loud quasar at z 3. In spite of the large distance of the object we are able to detect its surrounding extended ne…
Arnol'd Tongues and Quantum Accelerator Modes
Italo Guarneri, Laura Rebuzzini, Shmuel Fishman
The stable periodic orbits of an area-preserving map on the 2-torus, which is formally a variant of the Standard Map, have been shown to explain the quantum accelerator modes that…
Double Transverse-Spin Asymmetries in Drell-Yan Processes with Antiprotons
Vincenzo Barone, Alessandro Cafarella, Claudio Coriano' +2
We present next-to-leading order predictions for double transverse-spin asymmetries in Drell--Yan dilepton production initiated by proton--antiproton scattering. The kinematic regi…
