Momentum/Complexity Duality and the Black Hole Interior
José L. F. Barbón, Javier Martín-García, Martin Sasieta
We establish a version of the Momentum/Complexity (PC) duality between the rate of operator complexity growth and a radial component of bulk momentum for a test system falling into…
Holographic Bulk Reconstruction And Cosmological Singularities
José L. F. Barbón, Martin Sasieta
We study the structure of entanglement wedges in the Kasner-AdS geometry, which provides an example of AdS/CFT engineered cosmological singularity. We investigate the specific limi…
Complex World-Sheets from N=2 Strings
J. L. F. Barbon, M. A. Vazquez-Mozo
We study some properties of target space strings constructed from (2,1) heterotic strings. We argue that world-sheet complexification is a general property of the bosonic sector of…
T-duality for open strings
E. Alvarez, J. L. F. Barbon, J. Borlaf
The T-duality transformations between open and closed superstrings in different D-manifolds are generalized to curved backgrounds with commuting isometries. We address some global…
D-brane form factors at high energy
J. L. F. Barbon
We study the high energy, fixed angle, asymptotics of D-brane form factors to all orders in string perturbation theory, using the Gross-Mende saddle point techniques. The effective…
Generalized Abelian S-duality and coset constructions
J. L. F. Barbon
Electric-magnetic duality and higher dimensional analogues are obtained as symmetries in generalized coset constructions, similar to the axial-vector duality of two dimensional cos…
Quantum black hole entropy and Newton constant renormalization
J. L. F. Barbon, R. Emparan
We discuss the status of the black hole entropy formula in low energy effective field theory. The low energy expansion of the black hole entropy is studied i…
Correlation Functions in Matrix Models Modified by Wormhole Terms
J. L. F. Barbón, K. Demeterfi, I. ~R. Klebanov +1
We calculate correlation functions in matrix models modified by trace-squared terms. First we study scaling operators in modified one-matrix models and find that their correlation…
Remarks on Thermal Strings outside Black Holes
J. L. F. Barbon
We discuss the semiclassical approximation to the level density of (super) strings propagating in non-compact coset manifolds . We show that the WKB ansatz agrees with heurist…
Effective hamiltonians for 1/N expansion in two-dimensional QCD
J. L. F. Barbón, Krešimir Demeterfi
We discuss the general structure of effective hamiltonians for systematic 1/N expansion in QCD using the light-cone quantization. These are second-quantized hamiltonians acting on…
