The Horizon Order Parameter
N. Itzhaki
We construct a diffeormorphism invariant operator that is sensitive to how far we are from the black hole horizon. Its expectation value blows up on the horizon and it is small awa…
Observables of Non-Commutative Gauge Theories
David J. Gross, Akikazu Hashimoto, N. Itzhaki
We construct gauge invariant operators in non-commutative gauge theories which in the IR reduce to the usual operators of ordinary field theories (e.g. F^2). We show that in the de…
A Comment on the Entropy of Strongly Coupled N=4
N. Itzhaki
We propose a field theory argument, which rests on the non-renormalization of the two point function of the energy-momentum tensor, why the ratio between the entropies of strongly…
Is the Black Hole Complementarity principle really necessary?
N. Itzhaki
We show that the S-matrix ansatz implies a semi-classical metric such that a freely falling test particle will not cross the horizon in its proper time. Instead of reaching the sin…
