B-type anomaly coefficients for the D3-D5 domain wall
Marius de Leeuw, Charlotte Kristjansen, Georgios Linardopoulos +1
We compute type-B Weyl anomaly coefficients for the domain wall version of N = 4 SYM that is holographically dual to the D3-D5 probe-brane system with flux. Our starting point is t…
Holographic correlators of semiclassical states in defect CFTs
George Georgiou, Georgios Linardopoulos, Dimitrios Zoakos
We set up the computation of correlation functions for operators that are dual to semiclassical string states in strongly coupled defect conformal field theories (dCFTs). In the dC…
Finite volume form factors in integrable theories
Zoltan Bajnok, Georgios Linardopoulos, István M. Szécsényi +1
We develop a new method to calculate finite size corrections for form factors in two-dimensional integrable quantum field theories. We extract these corrections from the excited st…
String integrability of the ABJM defect
Georgios Linardopoulos
ABJM theory in the presence of a half-BPS domain wall is dual to the D2-D4 probe brane system with nonzero worldvolume flux. The ABJM domain wall was recently shown to be integrabl…
Cascade of instabilities in the classical limit of the BMN matrix model
Minos Axenides, Emmanuel Floratos, Dimitrios Katsinis +1
We study the leading (LO) and the next-to-leading order (NLO) stability of multipole perturbations for a static dielectric M2-brane with spherical topology in the 11-dimensional ma…
String integrability of defect CFT and dynamical reflection matrices
Georgios Linardopoulos, Konstantin Zarembo
The D3-D5 probe-brane system is holographically dual to a defect CFT which is known to be integrable. The evidence comes mainly from the study of correlation functions at weak coup…
M-theory as a dynamical system generator
Minos Axenides, Emmanuel Floratos, Dimitrios Katsinis +1
We review our recent work on ellipsoidal M2-brane solutions in the large-N limit of the BMN matrix model. These bosonic finite-energy membranes live inside SO(3)xSO(6) symmetric pl…
Solving holographic defects
Georgios Linardopoulos
Defect conformal field theories (dCFTs) have been attracting increased attention recently, mainly because they enable us to bridge the gap between idealistic, highly symmetric mode…
Spin Chain Overlaps and the Twisted Yangian
Marius de Leeuw, Tamás Gombor, Charlotte Kristjansen +2
Using considerations based on the thermodynamical Bethe ansatz as well representation theory of twisted Yangians we derive an exact expression for the overlaps between the Bethe ei…
Scalar one-point functions and matrix product states of AdS/dCFT
Marius de Leeuw, Charlotte Kristjansen, Georgios Linardopoulos
We determine in a closed form all scalar one-point functions of the defect CFT dual to the D3-D5 probe brane system with k units of flux which amounts to calculating the overlap be…
Multipole Stability of Spinning M2-branes in the Classical Limit of the BMN Matrix Model
Minos Axenides, Emmanuel Floratos, Georgios Linardopoulos
We explore the stability of a recently found class of spinning dielectric M2-branes in the 11-dimensional maximally supersymmetric plane-wave background. We find two small windows…
M2-brane Dynamics in the Classical Limit of the BMN Matrix Model
Minos Axenides, Emmanuel Floratos, Georgios Linardopoulos
We investigate the large-N limit of the BMN matrix model by analyzing the dynamics of ellipsoidal M2-branes that spin in the 11-dimensional maximally supersymmetric SO(3)xSO(6) pla…
One-Point Functions of Non-protected Operators in the SO(5) symmetric D3-D7 dCFT
Marius de Leeuw, Charlotte Kristjansen, Georgios Linardopoulos
We study tree level one-point functions of non-protected scalar operators in the defect CFT, based on N=4 SYM, which is dual to the SO(5) symmetric D3-D7 probe brane system with no…
New Minimal Hypersurfaces in R(k+1)(2k+1) and S(2k+3)k
Jens Hoppe, Georgios Linardopoulos, O. Teoman Turgut
We find a class of minimal hypersurfaces H(k) as the zero level set of Pfaffians, resp. determinants of real 2k+2 dimensional antisymmetric matrices. While H(1) and H(2) are congru…
The Omega-Infinity Limit of Single Spikes
Minos Axenides, Emmanuel Floratos, Georgios Linardopoulos
A new infinite-size limit of strings in RxS2 is presented. The limit is obtained from single spike strings by letting by letting the angular velocity parameter omega become infinit…
Large-Spin Expansions of Giant Magnons
Georgios Linardopoulos
This is a talk delivered at the Workshop on Quantum Fields and Strings of the 2014 Corfu Summer Institute. We discuss how giant magnons emerge in the context of the AdS5/CFT4 corre…
Large-Spin and Large-Winding Expansions of Giant Magnons and Single Spikes
Emmanuel Floratos, Georgios Linardopoulos
We generalize the method of our recent paper on the large-spin expansions of Gubser-Klebanov-Polyakov (GKP) strings to the large-spin and large-winding expansions of finite-size gi…
Large-Spin Expansions of GKP Strings
Emmanuel Floratos, George Georgiou, Georgios Linardopoulos
We demonstrate that the large-spin expansion of the energy of Gubser-Klebanov-Polyakov (GKP) strings that rotate in RxS2 and AdS3 can be expressed in terms of Lambert's W-function.…
Stringy Membranes in AdS/CFT
Minos Axenides, Emmanuel Floratos, Georgios Linardopoulos
We study membrane configurations in AdS_{7/4}xS^{4/7}. The membranes are wrapped around the compact manifold S^{4/7} and are dynamically equivalent to bosonic strings in AdS_5. We…
