Beyond the Random Phase Approximation for the Electron Correlation Energy: The Importance of Single Excitations
Beyond the Random Phase Approximation Electron Correlation Importance of Single Excitations
2010/11/22
The random phase approximation (RPA) for the electron correlation energy, combined with
the exact-exchange energy, represents the state-of-the-art exchange-correlation functional within density-funct...
Superconducting nanowire single photon detectors for quantum information and communications
Superconducting nanowire single photon detectors quantum key distribution Gifford-McMahon
2010/3/10
Superconducting nanowire single photon detectors (SNSPD or SSPD) are highly promising devices in the growing field of quantum information and communications technology. We have developed a practical S...
NNLL resummation for s-channel single top quark production

2010/3/15
I present the next-to-next-to-leading-logarithm (NNLL) resummation of soft and collinear gluon corrections to single top quark production in the s channel. Attaining NNLL accuracy involves the calcula...

2010/3/15
We report a search for single top quark production with the CDF II detector using 2.1 fb-1 of integrated luminosity of pbar p collisions at sqrt{s}=1.96 TeV. The data selected consist of events charac...
Experimental study on the performance of a single-THGEM gas detector
gas electron multipliers hole multiplier effective gain energy resolution
2009/12/24
A kind of thick GEM-like gaseous electron multiplier (THGEM), which is mechanically an expansion of the GEM with its various dimensions being enlarged, is studied. The leak current of THGEM plates is...
Since the first lasers appeared nearly 50 years ago, scientists and engineers have dreamt about creating all-optical circuits in which electrons are replaced by photons. While information is easily tr...
Universal quantum limits on single channel information, entropy and heat flow
Universal quantum limits single channel information , entropy heat flow
2010/10/13
We show that the recently discovered universal upper bound on the thermal conductance of a single channel comprising particles obeying arbitrary fractional statistics is in fact a consequence of a mor...

Electrical resistance transition metal dichalcogenides single crystal structural phase transition
2010/4/8
Single crystals of Mo0.5W0.5S2 were grown by chemical vapour transport and direct vapour transport techniques. The crystals have been characterized by X-ray energy dispersive analysis and X-ray powder...
Single Mode Optical Radiation Distribution and Reflectivity Calculations in Novel-Hot Electron Light Emission and Lasing In Semiconductor Heterostructures VCSELs
Optical Radiation Distribution Electron Light Emission Reflectivity Calculations
2010/4/12
In this work, we calculate the power reflectivity in vertical cavity surface emitting lasers (VCSELs) using a new method. In VCSELs, the stop band of the reflectivity spectrum should exhibit a dip at ...
