Observables of String Field Theory
Akikazu Hashimoto, N. Itzhaki
We study gauge invariant operators of open string field theory and find a precise correspondence with on-shell closed strings. We provide a detailed proof of the gauge invariance o…
Black Hole Horizon Fluctuations
A. Casher, F. Englert, N. Itzhaki +2
It is generally admitted that gravitational interactions become large at an invariant distance of order from the black hole horizon. We show that due to the ``atmosphere'' of h…
Black Hole Information vs. Locality
N. Itzhaki
We discuss the limitations on space time measurement in the Schwarzchild metric. We find that near the horizon the limitations on space time measurement are of the order of the bla…
Some Interesting Properties of Field theories with an Infinite Number of Fields
N. Itzhaki
We give an indication that gravity coupled to an infinite number of fields might be a renormalizable theory. A toy model with an infinite number of interacting fermions in four-dim…
