Double-Scaling Limit in Principal Chiral Model: a New Non-Critical String?
Vladimir Kazakov, Evgeny Sobko, Konstantin Zarembo
We initiate a systematic, non-perturbative study of the large- expansion in the two-dimensional Principal Chiral Model (PCM). Starting with the…
Integrability in Sigma-Models
K. Zarembo
This is a write-up of lectures on integrable sigma-models, which covers the following topics: (1) Homogeneous spaces, (2) Classical integrability of sigma-models in two dimensions,…
Fine Structure of String Spectrum in AdS(5)xS(5)
K. Zarembo, S. Zieme
The spectrum of an infinite spinning string in AdS(5) does not precisely match the spectrum of dual gauge theory operators, interpolated to the strong coupling regime with the help…
Quantum Giant Magnons
K. Zarembo
The giant magnons are classical solitons of the O(N) sigma-model, which play an important role in the AdS/CFT correspondence. We study quantum giant magnons first at large N and th…
World-sheet scattering in AdS_5 x S^5 at two loops
T. Klose, T. McLoughlin, J. A. Minahan +1
We study the AdS_5 x S^5 sigma-model truncated to the near-flat-space limit to two-loops in perturbation theory. In addition to extending previously known one-loop results to the f…
Matching quantum strings to quantum spins: one-loop vs. finite-size corrections
N. Beisert, A. A. Tseytlin, K. Zarembo
We compare quantum corrections to semiclassical spinning strings in AdS(5)xS(5) to one-loop anomalous dimensions in N=4 supersymmetric gauge theory. The latter are computed using t…
Complete Spectrum of Long Operators in N=4 SYM at One Loop
N. Beisert, V. A. Kazakov, K. Sakai +1
We construct the complete spectral curve for an arbitrary local operator, including fermions and covariant derivatives, of one-loop N=4 gauge theory in the thermodynamic limit. Thi…
The Algebraic Curve of Classical Superstrings on AdS_5xS^5
N. Beisert, V. A. Kazakov, K. Sakai +1
We investigate the monodromy of the Lax connection for classical IIB superstrings on AdS_5xS^5. For any solution of the equations of motion we derive a spectral curve of degree 4+4…
Semiclassical Bethe Ansatz and AdS/CFT
K. Zarembo
The Bethe ansatz can be used to compute anomalous dimensions in N=4 SYM theory. The classical solutions of the sigma-model on AdS(5)xS(5) can also be parameterized by an integral e…
Yang-Mills Duals for Semiclassical Strings
J. Engquist, J. A. Minahan, K. Zarembo
We consider a semiclassical multiwrapped circular string pulsating on S_5, whose center of mass has angular momentum J on an S_3 subspace. Using the AdS/CFT correspondence we argue…
Wilson loops in N=4 SYM theory: rotation in S5
A. A. Tseytlin, K. Zarembo
We study Wilson loops in N=4 SYM theory which are non-constant in the scalar (S5) directions and open string solutions associated with them in the context of AdS/CFT correspondence…
