Instant Cosmology
Nissan Itzhaki, Uri Peleg
Instant Folded Strings (IFSs) are unconventional light strings that emerge when the string coupling increases with time. A particularly intriguing property of IFSs, especially rele…
When Strings Surprise
N. Itzhaki, U. Peleg
We argue that on-shell excitations with large negative energies are created rapidly when the string coupling increases with time. This does not indicate an inconsistency in string…
A Worldsheet Description of Instant Folded Strings
Akikazu Hashimoto, Nissan Itzhaki, Uri Peleg
Time-like linear dilaton backgrounds admit a classical solution that describes a closed folded string that is created at an instant. We refer to such strings as Instant Folded Stri…
Instant Folded Strings and Black Fivebranes
Amit Giveon, Nissan Itzhaki, Uri Peleg
We study the recent claim that black NS5-branes are filled with folded strings. We calculate, in the near-extremal case, the number of folded strings at the black fivebranes interi…
