Effective field theory for closed strings near the Hagedorn temperature
Journal of High Energy Physics, 2021 We discuss interacting, closed, bosonic and superstrings in thermal equilibrium at temperatures close to the Hagedorn temperature in flat space. We calculate S-matrix elements of the strings at the Hagedorn temperature and use them to construct a low ...

, 1994 Above the Hagedorn energy density closed fundamental strings form a long string phase. The dynamics of weakly interacting long strings is described by a simple Boltzmann equation which can be solved explicitly for equilibrium distributions.

Rotating Strings in Confining AdS/CFT Backgrounds [PDF]
, 2002 We study semiclassical rotating strings in AdS/CFT backgrounds that exhibit both confinement and finite-size effects. The energy versus spin dispersion relation for short strings is the expected Regge trajectory behaviour, with the same string tension as

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 ...

Black hole entropy and long strings
International Journal of Modern Physics D, 2022 In this paper, we discuss whether black hole entropy counts short or long-range microstates in quantum gravity. In brick wall and induced gravity models, the entropy arises due to short distance correlations across the event horizon cut off at the Planck length.

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 ...

Evolution of cosmic string networks [PDF]
, 1989 Results on cosmic strings are summarized including: (1) the application of non-equilibrium statistical mechanics to cosmic string evolution; (2) a simple one scale model for the long strings which has a great deal of predictive power; (3) results from ...

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.
