Tachyon condensation and universality of DBI action
(Institute of Physics, 2001)
We show that a low-energy action for massless fluctuations around a tachyonic soliton
background representing a codimension one D-brane coincides with the Dirac-Born-Infeld
action. The scalar modes which describe transverse ...
Three-point Green function of the stress-energy tensor in the AdS/CFT correspondence
(Institute of Physics, 1999)
We compute the three-point function of the stress-energy tensor in d-dimensional conformal field theory
CFT from AdSd11 gravity. For d54 the coefficients of the three linearly independent conformally covariant
forms ...
Finite-size Effects from Giant Magnons.
(Elsevier, 2007)
In order to analyze finite-size effects for the gauge-fixed string sigma model on AdS5?S5, we construct one-soliton solutions carrying finite angular momentum J. In the infinite J limit the solutions reduce to the recently ...
The Zamolodchikov-Faddeev Algebra for AdS_5 x S^5 Superstring
(2007)
We discuss the Zamolodchikov-Faddeev algebra for the superstring sigmamodel
on AdS5 ? S5. We find the canonical su(2|2)2 invariant S-matrix satisfying the
standard Yang-Baxter and crossing symmetry equations. Its ...
On one-loop correction to energy of spinning strings in S(5)
(American Physical Society, 2005)
We revisit the computation of the 1-loop AdS5?S5 superstring sigma model correction to the energy of a closed circular string rotating in S5. The string is spinning around its center of mass with two equal angular momenta ...
Operator product expansion of the lowest weight CPOs in N = 4 SYM(4) at strong coupling
(2000)
We present a detailed analysis of the 4-point functions of the lowest weight chiral primary
operators OI ~ tr?(i?j) in N = 4 SYM4 at strong coupling and show that their structure
is compatible with the predictions of ...
Konishi operator at intermediate coupling.
(2011)
TBA equations for two-particle states from the sl(2) sector proposed by
Arutyunov, Suzuki and the author are solved numerically for the Konishi operator
descendent up to 't Hooft's coupling 2046. The data obtained ...
Removing fermion doublers in chiral gauge theories on the lattice
(Elsevier, 1994)
A method for removing fermion doublers in anomaly free chiral gauge
theories on the lattice is proposed. It is proven that the resulting continuum
theory is gauge invariant and does not require noninvariant counterterms ...
