The fine structure of the dynamics of seismicity before earthquakes in the area of Reggio Emilia (Northern Italy)
seismicity earthquakes prognostic parameter seismic quiescence foreshock activation
2015/9/30
We present the results of studies of seismicity in the Reggio Emilia area (Northern Italy). The Istituto Nazionale di Geofisica instrumental earthquake catalogue (1975-1996) reported about three moder...
Optical transitions in highly-charged californium ions with high sensitivity to variation of the fine-structure constant
Optical transitions highly-charged californium ions variation of the fine-structure constant Atomic Physics
2012/4/19
We study electronic transitions in highly-charged Cf ions that are within the frequency range of optical lasers and have very high sensitivity to potential variations in the fine-structure constant, a...
Future constraints on variations of the fine structure constant from combined CMB and weak lensing measurements
Future constraints variations fine structure constant combined CMB weak lensing measurements
2012/2/21
We forecast the ability of future CMB and galaxy lensing surveys to constrain variations of the fine structure constant. We found that lensing data, as those expected from satellite experiments as Euc...
Synchrotron based Transmission x-ray microscopy reveals smectite fine structure in an aqueous environment
Synchrotron Transmission x-ray microscopy reveals smectite fine structure aqueous environment
2012/3/30
The unusual behaviour of smectites, the ability to change volume when wetted (swelling) or dried (shrinking), make soil containing smectites very unstable and hazardous for the building industry due t...
Spin Scissors Mode and the Fine Structure of M1 States in Nuclei
Spin Scissors Mode M1 States Fine Structure
2011/7/20
The coupled dynamics of low lying modes, including the scissors mode, and various giant quadrupole resonances are studied with the help of the Wigner Function Moments method generalized to take into a...
A view of the narrow-line region in the infrared: active galactic nuclei with resolved fine-structure lines in the Spitzer archive
narrow-line region infrared: active galactic nuclei resolved fine-structure lines
2011/10/10
We queried the Spitzer archive for high-resolution observations with the Infrared Spectrograph of optically selected active galactic nuclei (AGN) for the purpose of identifying sources with resolved f...
Intensity Mapping of the [CII] Fine Structure Line during the Epoch of Reionization
Intensity Mapping Fine Structure Line during Epoch Reionization
2011/10/11
The atomic CII fine-structure line is one of the brightest lines in a typical star-forming galaxy spectrum with a luminosity ~ 0.1% to 1% of the bolometric luminosity. It is potentially a reliable tra...
Domain wall solution in $F(R)$ gravity and variation of the fine structure constant

2011/10/18
We construct a domain wall solution in $F(R)$ gravity. We first compare a scalar field theory having a runaway type potential with a corresponding scalar field theory obtained through a conformal tran...

Fine structure；HgTe/HgCdTe quantum wells
2010/11/25
HgTe/HgCdTe quantum wells with the inverted band structure have been probed using far infrared
magneto-spectroscopy. Realistic calculations of Landau level diagrams have been performed to
identify t...
The effective fine structure constant of freestanding graphene measured in graphite
