An ultra-high vacuum scanning tunneling microscope operating at sub-Kelvin temperatures and high magnetic fields for spin-resolved measurements
We present the construction and performance of an ultra-low-temperature scanning tunneling microscope (STM), working in ultra-high vacuum (UHV) conditions and in high magnetic fields up to 9 T. The cryogenic environment ...
Effectiveness of intraoral suction systems and aspirating tips for evacuation of aluminum oxide particles during use of air-abrasion
(2010-04-01)
Aim: The purpose of this study was to compare the effectiveness of a high-volume evacuation and a conventional intraoral suction system and aspirating tips for capturing aluminum oxide particles during use of an air-abrasion ...

QCD vacuum topology and glueballs
(American Institute of Physics (AIP), 2004-01-01)
We outline a comprehensive study of spin-0 glueball properties which, in particular, keeps track of the topological gluon structure. Specifically, we implement (semi-hard) topological instanton physics as well as topological ...
Infrared finite solutions for the gluon propagator and the QCD vacuum energy
(1997-07-31)
Nonperturbative infrared finite solutions for the gluon polarization tensor have been found, and the possibility that gluons may have a dynamically generated mass is supported by recent Monte Carlo simulation on the lattice. ...
Vacuum stability and the dynamics of chiral symmetry breaking
(1985-10-24)
An effective potential for composite operators is computed at stationary points with different ansatze for the fermion self-energy in abelian and non-abelian theories. The vacuum shows a chiral asymmetric phase with larger ...

Design and Characterization of a High Vacuum Metals Deposition System based on Electron Beam Evaporation
(2010-08-03)
We describe a high vacuum metals deposition system based ona variation of a pendant-drop type electron beam evaporator.This system uses a Molybdenum crucible as an evaporantinstead of a rod or wire usually used in ultrathin ...
