On the Nature of Kink MHD Waves, Vorticity and Compressibility Versus Restoring Forces by Karam Bahari

“…In order to study the nature of kink MHD waves, zero beta plasma in a thin twisted magnetic-flux tube is considered. We use two parameters, the ratio of restoring forces and the ratio of the parallel vorticity to the compressibility to study the effect of magnetic twist on the nature of kink waves. …”

A Study of Confinement for QQ- Potentials on D3, M2, and M5 Branes by Edward Quijada, Henrique Boschi-Filho

“…This is in agreement with the behaviour of strings in flat space where the string mimics the expected flux tube of QCD. A study of the transition between the confining/nonconfining regimes in the three different scenarios (D3, M2, and M5) is also performed.…”

Collisionality scaling of the electron heat flux in ETG turbulence by Colyer, G, Schekochihin, A, Parra, F, Roach, C, Barnes, M, Ghim, Y, Dorland, W

“…In electrostatic simulations of MAST plasma at electron-gyroradius scales, using the local flux-tube gyrokinetic code GS2 with adiabatic ions, we find that the long-time saturated electron heat flux (the level most relevant to energy transport) decreases as the electron collisionality decreases. …”

Scalar-gauge dynamics in (2+1) dimensions at small and large scalar couplings by Philipsen, O, Teper, M, Wittig, H

“…We study the crossover region at large scalar coupling and present a scenario how the confining properties of the model in the symmetric phase are lost inside the crossover by means of flux tube decay. We conclude that the underlying dynamics responsible for the observed dense spectrum of states in the Higgs region at large couplings must be different from that in the symmetric phase. © 1998 Elsevier Science B.V.…”

An operator product expansion for polygonal null Wilson loops by Alday, L, Gaiotto, D, Maldacena, J, Sever, A, Vieira, P

“…These subleading corrections are governed by excitations of high spin operators, or excitations of a flux tube that goes between two Wilson lines. The discussion is valid for any conformal gauge theory, for any coupling and in any dimension. …”

On the mass of the world-sheet `axion' in SU(N) gauge theories in 3+1 dimensions by Athenodorou, A, Teper, M

“…There is numerical evidence that the world sheet action of the confining flux tube in D =3 +1SU(N)gauge theories contains a massive excitation with 0−quantum numbers whose mass shows some decrease as one goes from SU(3)to SU(5). …”

Effects of toroidally-distributed-divertor biasing on scrape-off-layer (SOL) current drive, divertor particle flux and fast electron confinement in the QUEST spherical tokamak by Kazuo Toi, Takumi Onchi, Hideki Zushi, Kengoh Kuroda, Hiroshi Idei, Kazuaki Hanada, Makoto Hasegawa, Shinichiro Kojima, Ryuya Ikezoe, Takeshi Ido, Shoji Kawasaki, Aki Higashijima, QUEST Experiment Group

“…In the ST plasmas of line averaged electron density < ${n_e}$ > ∼0.7–1 × 10 ^18 m ^−3 , about 20%–40% of the current ${I_{{\text{bias}}}}$ driven by ∼85 V sawtooth bias voltage reaches the lower divertor plate along the biased scrape-off-layer (SOL) flux tube as the SOL current ${I_{{\text{SOL}}}}$ . …”

Study of fast-ion-driven toroidal Alfvén eigenmodes impacting on the global confinement in TCV L-mode plasmas by S. Mazzi, S. Mazzi, M. Vallar, U. Kumar, O. Krutkin, J. Poley-Sanjuan, L. Simons, J. Ball, S. Brunner, S. Coda, J. Garcia, A. Iantchenko, Ye. O. Kazakov, W. H. Lin, J. Ongena, B. Rofman, L. Villard, the TCV team

“…Attempts to simulate the simultaneous presence of fast-ion driven TAEs and TEM turbulence show that elongated streamers develop up to the full radial extent of the flux-tube domain, thereby invalidating the local assumption and indicating that a global approach is mandatory in these TCV plasmas.…”

Generation of Alfvén waves in magnetized plasma by laser plasma bunches at Mach numbers much less than unity by Tishchenko V. N., Berezutsky A. G., Dmitrieva L. R., Miroshnichenko I. B., Shaikhislamov I. F.

“…In this paper, we examine a torsional Alfvén wave produced by periodic plasma bunches in a magnetized plasma flux tube. A new effect has been revealed: the wave is generated not only during the action of bunches, but also for a long time after the termination, which makes it possible to increase the wavelength by several times. …”

Persistence of Ion Cyclotron Waves and Stochasticity of Kinetic Alfvén Waves in the Solar Wind by Daniele Telloni

“…Specifically, while the stochastic character of KAWs may be reminiscent of the random convection-driven jostling of the flux-tube foot-points that generates the Alfvén waves in the lower solar atmosphere, the correlations among the ICW events can be effectively explained on the basis of the persistent nature of the mechanism underlying the local origin of ICWs, namely the proton cyclotron instability. …”

QED Mesons, the QED Neutron, and the Dark Matter by Wong Cheuk-Yin

“…Just as the open-string QCD excitations in 1+1D can be the idealization of QCD mesons with a flux tube in 3+1D, so the open-string QED excitations in 1+1D may likewise be the idealization of QED mesons with masses in the tens of MeV region, corresponding possibly to the anomalous X17 and E38 particles observed recently. …”

Gauge Theories of Josephson Junction Arrays: Why Disorder Is Irrelevant for the Electric Response of Disordered Superconducting Films by Carlo A. Trugenberger

Observations and Simulations of a Double‐Core Hot Flow Anomaly by Xi Lu, Antonius Otto, Hui Zhang, Terry Liu, Xingran Chen

“…The observation via the Acceleration, Reconnection, Turbulence and Electrodynamics of the Moon's Interaction with the Sun (ARTEMIS) mission suggests this MHD HFA is associated with a foreshock density hole‐like structure. The trailing flux tube in simulation may propagate with a TD in the foreshock. …”

Tubular Initial Conditions and Ridge Formation by M. S. Borysova, O. D. Borysov, Iu. A. Karpenko, V. M. Shapoval, Yu. M. Sinyukov

“…This study's objective is to analyze whether multiform initial tubular structures, undergoing the subsequent hydrodynamic evolution and gradual decoupling, can form the soft ridges. Motivated by the flux-tube scenarios, the initial energy density distribution contains the different numbers of high density tube-like boost-invariant inclusions that form a bumpy structure in the transverse plane. …”

A phase-shift-periodic parallel boundary condition for low-magnetic-shear scenarios by St-Onge, DA, Barnes, M, Parra, FI

“…While this phase shift can be set to zero without loss of generality in the local flux-tube limit when employing the twist-and-shift boundary condition, we show that this is not the most general case when employing periodic parallel boundaries, and may not even be the most desirable. …”
