Black string and velocity frame dragging [PDF]
Modern Physics Letters A, 2008 We investigate velocity frame dragging with the boosted Schwarzschild black string solution and the boosted Kaluza-Klein bubble solution, in which a translational symmetry along the boosted $z$-coordinate is implemented.

Effects of Cosmic String Velocities and the Origin of Globular Clusters [PDF]
Journal of Cosmology and Astroparticle Physics, 2015 With the hypothesis that cosmic string loops act as seeds for globular clusters in mind, we study the role that velocities of these strings will play in determining the mass distribution of globular clusters.

Langevin Diffusion in Holographic Backgrounds with Hyperscaling Violation
Advances in High Energy Physics, 2014 We consider a relativistic heavy quark which moves in the quark-gluon plasmas. By using the holographic methods, we analyze the Langevin diffusion process of this relativistic heavy quark.

Examples of discriminating the downward depth and downward timing of the velocity string in the water-producing gas well [PDF]
E3S Web of Conferences, 2021 The problem of bottom hole effusion is an important reason for the reduction and even shutdown of natural gas wells. Downward velocity string is an important drainage gas recovery process, which can improve the flow rate of gas and discharge more liquid ...

Cosmic string induced peculiar velocities [PDF]
The Astrophysical Journal, 1988 This paper considers the scenario of a flat universe with a network of heavy cosmic strings as the primordial fluctuation spectrum. The joint probability of finding streaming velocities of at least 600 km/s on large scales and local peculiar velocities of less than 800 km/s is calculated.

Evolution of semilocal string networks. II. Velocity estimators [PDF]
Physical Review D, 2017 We continue a comprehensive numerical study of semilocal string networks and their cosmological evolution. These can be thought of as hybrid networks comprised of (non-topological) string segments, whose core structure is similar to that of Abelian Higgs vortices, and whose ends have long--range interactions and behaviour similar to that of global ...

String breaking in a cold wind as seen by string models
Nuclear Physics B, 2022 Using the gauge/string duality, we model a heavy quark-antiquark pair in a color singlet state moving through a cold medium and explore the consequences of temperature and velocity on string breaking. In doing so, we restrict to the case of two dynamical

Superradiance and black resonator strings encounter helical black strings
Journal of High Energy Physics, 2023 We construct a cohomogeneity-1 helical black string in six-dimensional Einstein gravity. The helical solution branches from the onset of the gravitational superradiant instability of the equal-spinning Myers-Perry black string.
