Long-range effects of cosmic string structure [PDF]

Physical Review D, 1996
We combine and further develop ideas and techniques of Allen \& Ottewill, Phys. Rev.D, {\bf 42}, 2669 (1990) and Kay \& Studer Commun. Math. Phys., {\bf 139}, 103 (1991) for calculating the long range effects of cosmic string cores on classical and quantum field quantities far from an (infinitely long, straight) cosmic string.

Instruction Sequences Expressing Multiplication Algorithms [PDF]

Scientific Annals of Computer Science, 2018
For each function on bit strings, its restriction to bit strings of any given length can be computed by a finite instruction sequence that contains only instructions to set and get the content of Boolean registers, forward jump instructions, and a ...

Testing Distributions of Huge Objects [PDF]

TheoretiCS, 2023
We initiate a study of a new model of property testing that is a hybrid of testing properties of distributions and testing properties of strings. Specifically, the new model refers to testing properties of distributions, but these are distributions over ...

Quantizing the rotating string with massive endpoints

Journal of High Energy Physics, 2018
We compute leading order quantum corrections to the Regge trajectory of a rotating string with massive endpoints using semiclassical methods. We expand the bosonic string action around a classical rotating solution to quadratic order in the fluctuations ...

Stability analysis of classical string solutions and the dressing method

Journal of High Energy Physics, 2019
The dressing method is a technique to construct new solutions in non-linear sigma models under the provision of a seed solution. This is analogous to the use of autoBäcklund transformations for systems of the sine-Gordon type.

On finite-size spiky strings in AdS 3 × S 3 × T 4 with mixed fluxes

Journal of High Energy Physics, 2020
We discuss finite-size corrections to the spiky strings in AdS space which is dual to the long 𝒩 = 4 SYM operators of the form Tr( Δ + J 1 ϕ 1 Δ + J 2 ϕ 2 … Δ + J n ϕ n $$ {\varDelta}_{+}^{J_1}{\phi}_1{\varDelta}_{+}^{J_2}{\phi}_2\dots {\varDelta}_ ...

Twisted strings in three-dimensional black holes

European Physical Journal C: Particles and Fields, 2022
We revisit the classical dynamics of fundamental strings in BTZ black holes with NSNS flux. We analyze probe strings in the black hole background and determine their classical energy using a Nambu–Goto action.

Transient chaos analysis of string scattering

Journal of High Energy Physics, 2022
It has long been thought that a highly excited string can be regarded as a black hole: the correspondence principle between strings and a black hole, while recent studies found that black holes are characterized by chaos.

Spectrum of the open QCD flux tube and its effective string description I: 3d static potential in SU(N = 2, 3)

Journal of High Energy Physics, 2017
We perform a high precision measurement of the static q q ¯ $$ q\overline{q} $$ potential in three-dimensional SU(N) gauge theory with N = 2, 3 and compare the results to the potential obtained from the effective string theory.
