CMB Injection Bounds on Moduli Fields
Naman Agarwal, Andrew R. Frey, Ratul Mahanta +3
Light scalar fields with gravitational strength interactions (moduli) are ubiquitous in string, supergravity, and extra-dimensional models. If produced in the early universe with l…
The gauge invariance of non-perturbative vertex prescriptions
M. E. Carrington, A. R. Frey, B. A. Meggison
We study the gauge invariance of different continuum methods to include non-perturbative effects in gauge theories. We work with three dimensional quantum electrodynamics and imple…
Dimensional Reduction and Kähler Metric for Metric Moduli in Imaginary Self-Dual Flux
Andrew R. Frey, Ratul Mahanta
Understanding which effective field theories are consistent with an ultraviolet completion in quantum gravity is an important theoretical question. Therefore, it is important to kn…
Gravitational Waves from High Temperature Strings
Andrew R. Frey, Ratul Mahanta, Anshuman Maharana +2
We study finite temperature effects in string cosmology and their potential gravitational wave signature. Expanding on our recent work arXiv:2310.11494 , we consider a general conf…
String Thermodynamics In and Out of Equilibrium: Boltzmann Equations and Random Walks
Andrew R. Frey, Ratul Mahanta, Anshuman Maharana +3
We revisit the study of string theory close to the Hagedorn temperature with the aim towards cosmological applications. We consider interactions of open and closed strings in a gas…
