The simulations are obtained by introducing a 3 m Hz harmonic vertical perturbation at the axis of a magneto-static ﬂux tube.
Magnetic fingerprints of solar and stellar oscillations
The generally accepted interpretation is that a chromoelectric ﬂux tube (or open string ) forms between the two static charges, and the slope of the potential in the asymptotic regime is the string tension.
k-String tensions and the 1/N expansion
One may also consider ﬂux tubes wrapping around a spatial compact direction (closed strings ), which are not attached to any static charge.
k-String tensions and the 1/N expansion
The performance of this general relativistic Roe solver was tested in a number of one-dimensional problems for which exact solutions are known, including nonrelativistic shock tubes, special relativistic shock tubes and spherical accretion of dust and a perfect ﬂuid onto a (static) Schwarzschild black hole.
Numerical hydrodynamics in general relativity
One consisting of the frontal region continuously covering new tubes, and the other consisting of the more static structure behind the front.
A Numerical Study of Capillary and Viscous Drainage in Porous Media
Fig. 1: The gluonic ﬂux tube between static quark sources (Bali et al. ).
QCD Spectroscopy at Gsi: Exotica and Charmonia
The gluonic ﬂux tube and its translation into a static conﬁning potential between (inﬁnitely heavy) color sources has become ”reality” on the lattice.
Baryons 2002: Outlook
These include ﬁrst calculations of the strangeness magnetic moment of the nucleon, three new studies of the gluon propagator, ﬂux tube attraction in U (1) gauge theory, and the static-quark potential and its gluonic excitations.
News from the lattice
It is remarkable that the vertex function is actually a step function and it establishes a distance independent force between static world-tubes in suﬃciently long time.
Quantum-classical crossover in electrodynamics
The steady state in a vacuum tube requires that the static potential energy at a given point between the electrodes does not exceed that of the cathode.
