Experimental study of multi-photon contamination on the measurement offluorescent decay time
time correlation-single photon counting fluorescent lifetime multi-photon contamination
2009/8/17
In the measurement of fluorescent lifetime based on time correlation-single photon counting technique by means of TAC, due to the contamination of multi-photons a deviation of fluorescent lifetime mea...
Strong Limits on the Possible Decay of the Vacuum Energy into CDM or CMB Photons
the Vacuum Energy CDM CMB Photons
2010/10/18
We investigate models that suggest that the vacuum energy could decay into cold dark matter (CDM) or into a homogeneous distribution of thermalized cosmic microwave background (CMB) photons. We show t...
Spectral Derivation of the Ornstein-Zernike Decay for Four-Point Functions
Spectral Derivation the Ornstein-Zernike Decay Four-Point Functions
2010/10/14
In this note we discuss the relation between the Ornstein-Zernike decay of certain four-point functions (“energyenergy correlations”) in lattice spin systems and spectral properties of the transfer ma...
