More on the Spectrum of Perturbations in String Gas Cosmology
Robert H. Brandenberger, Sugumi Kanno, Jiro Soda +5
String gas cosmology is rewritten in the Einstein frame. In an effective theory in which a gas of closed strings is coupled to a dilaton gravity background without any potential fo…
String Gas Cosmology and Structure Formation
Robert H. Brandenberger, Ali Nayeri, Subodh P. Patil +1
It has recently been shown that a Hagedorn phase of string gas cosmology may provide a causal mechanism for generating a nearly scale-invariant spectrum of scalar metric fluctuatio…
Inflation Free, Stringy Generation of Scale-Invariant Cosmological Fluctuations in D = 3 + 1 Dimensions
Ali Nayeri
We propose an alternative scenario to cosmic inflation for producing the initial seeds of cosmic structures. The cosmological fluctuations are generated by thermal fluctuation of t…
Tensor Modes from a Primordial Hagedorn Phase of String Cosmology
Robert H. Brandenberger, Ali Nayeri, Subodh P. Patil +1
It has recently been shown that a Hagedorn phase of string gas cosmology can provide a causal mechanism for generating a nearly scale-invariant spectrum of scalar metric fluctuatio…
