Advanced Kelvin Probe Operational Methodology for Space Applications
G. Chiritoi, E. M. Popescu, A. A. Radu +7
We present a novel methodology for the operation of macroscopic Kelvin Probe instruments. The methodology is based on the use of a harmonic backing potential signal to drive the ti…
Analysis of Kelvin Probe Operational Models
Eugeniu M. Popescu
We present a study of several models on which Kelvin Probe instruments with flat and spherical tips rely for operation and for the determination of the contact potential difference…
Weak Equivalence Principle Test on a Sounding Rocket
James D. Phillips, Bijunath R. Patla, Eugeniu M. Popescu +4
SR-POEM, our principle of equivalence measurement on a sounding rocket, will compare the free fall rate of two substances yielding an uncertainty of E-16 in the estimate of η. Duri…
Topological Higher Gauge Theory - from BF to BFCG theory
F. Girelli, H. Pfeiffer, E. M. Popescu
We study generalizations of 3- and 4-dimensional BF-theory in the context of higher gauge theory. First, we construct topological higher gauge theories as discrete state sum models…
Higher Gauge Theory and Gravity in (2+1) Dimensions
R. B. Mann, Eugeniu M. Popescu
Non-abelian higher gauge theory has recently emerged as a generalization of standard gauge theory to higher dimensional (2-dimensional in the present context) connection forms, and…
Scalar and tensorial topological matter coupled to (2+1)-dimensional gravity:A.Classical theory and global charges
R. B. Mann, E. M. Popescu
We consider the coupling of scalar topological matter to (2+1)-dimensional gravity. The matter fields consist of a 0-form scalar field and a 2-form tensor field. We carry out a can…
