We present results from the first simulations of networks of Type I Abelian Higgs cosmic strings to include both matter and radiation eras and Cosmic Microwave Background (CMB) constraints. In Type I strings, the string tension is a slowly decreasing function of the ratio of the scalar and gauge mass-squared,β. We find that the mean string separation shows no dependence on β, and that the energy-momentum tensor correlators decrease approximately in proportion to the square of the string tension… 
Cosmic string in Abelian-Higgs model with enhanced symmetry — Implication to the axion domain-wall problem
Simulation in the 3+1 dimensional spacetime of the Abelian-Higgs model with an enhanced U(1) global symmetry finds that the number of the uncompensated strings which could cause can be highly suppressed at late times, suggesting that the present setup can be applied to the axions model without suffering from the axion domain-wall problem.
New type of string solutions with long range forces
We explore the formation and the evolution of the string network in the Abelian Higgs model with two complex scalar fields. A special feature of the model is that it possesses a global U(1) symmetry
Electroweak strings with dark scalar condensates and their stability
The stability of "visible" electroweak-type cosmic strings is investigated in an extension of the Standard Model (SM) by a minimal dark sector, consisting of a U(1) gauge field, broken spontaneously
Massive black holes at high redshifts from superconducting cosmic strings
The observation of quasars at high redshifts presents a mystery in the theory of black hole formation. In order to source such objects, one often relies on the presence of heavy seeds (M ≈ 10 M⊙) in
Stable Z-strings with topological polarization in two Higgs doublet model
Abstract We find that a Z-string is stable in a wide range of parameter space of the two Higgs doublet model due to a split into a pair of two topological Z-strings with fractional Z fluxes. This
Global 21cm absorption signal from superconducting cosmic strings
Superconducting cosmic strings emit electromagnetic waves between the times of recombination and reionization. Hence, they have an effect on the global 21cm signal. We compute the resulting
Gravitational waves from global cosmic strings and cosmic archaeology
Abstract Global cosmic strings are predicted in many motivated extensions to the Standard Model of particle physics, with close connections to axion dark matter physics. Recent studies suggest that,
Signal of Cosmic Strings in Cross-Correlation of 21-cm Redshift and CMB Polarization Maps
We study the signal of cosmic string wakes present before the time of reionization in the cross-correlation signal of 21-cm redshift and B-mode CMB polarization maps. The specific non-Gaussian signal

We present a comprehensive discussion on lattice techniques for the simulation of scalar and gauge field dynamics in an expanding universe. After reviewing the continuum formulation of scalar and


New CMB constraints for Abelian Higgs cosmic strings
We present cosmic microwave background (CMB) power spectra from recent numerical simulations of cosmic strings in the Abelian Higgs model and compare them to CMB power spectra measured by Planck. We

We report on the energy-momentum correlators obtained with recent numerical simulations of the Abelian Higgs model, essential for the computation of cosmic microwave background and matter
Cosmic Strings from Supersymmetric Flat Directions
Flat directions are a generic feature of the scalar potential in supersymmetric gauge field theories. They can arise, for example, from D-terms associated with an extra Abelian gauge symmetry. Even
Strictly anomaly mediated supersymmetry breaking
We consider an MSSM extension with anomaly mediation as the source of supersymmetry-breaking, and a U(1) symmetry which solves the tachyonic slepton problem, and introduces both the see-saw mechanism
CMB power spectrum contribution from cosmic strings using field-evolution simulations of the Abelian Higgs model
We present the first field-theoretic calculations of the contribution made by cosmic strings to the temperature power spectrum of the cosmic microwave background (CMB). Unlike previous work, in which
Big-Bang Nucleosynthesis and Gamma-Ray Constraints on Cosmic Strings with a large Higgs condensate
We consider constraints on cosmic strings from their emission of Higgs particles, in the case that the strings have a Higgs condensate with amplitude of order the string mass scale, assuming that a

We investigate cosmic string networks in the Abelian Higgs model using data from a campaign of large-scale numerical simulations on lattices of up to $4096^3$ grid points. We observe scaling or
Fitting cosmic microwave background data with cosmic strings and inflation.
A multiparameter likelihood analysis is performed to compare measurements of the cosmic microwave background (CMB) power spectra with predictions from models involving cosmic strings, finding a 2sigma detection of strings in the standard case of a primordial spectrum with power-law tilt ns.

We study the network of Type-I cosmic strings using the field-theoretic numerical simulations in the Abelian-Higgs model. For Type-I strings, the gauge field plays an important role, and thus we find
