On the Holographic S–Matrix
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by CERN Document Server On the Holographic S{matrix I.Ya.Aref’eva Steklov Mathematical Institute, Russian Academy of Sciences Gubkin St.8, GSP-1, 117966, Moscow, Russia Centro Vito Volterra, Universita di Roma Tor Vergata, Italy [email protected] Abstract The recent proposal by Polchinski and Susskind for the holographic flat space S– matrix is discussed. By using Feynman diagrams we argue that in principle all the information about the S–matrix in the interacting field theory in the bulk of the anti- de Sitter space is encoded into the data on the timelike boundary. The problem of locality of interpolating field is discussed and it is suggested that the interpolating field lives in a quantum Boltzmannian Hilbert space. 1 According to the holographic principle [1, 2] one should describe a field theory on a manifold M which includes gravity by a theory which lives on the boundary of M.Two prominent examples of the holography are the Matrix theory [3] and the AdS/CFT corre- spondence [4, 5, 6]. The relation between quantum gravity in the anti-de Sitter space and the gauge theory on the boundary could be useful for better understanding of both theories. In principle CFT might teach us about quantum gravity in the bulk of AdS. Correlation functions in the Euclidean formulation are the subject of intensive study (see for example [7]-[21]). The AdS/CFT correspondence in the Lorentz formulation is considered in [22]-[29]. -
6D Fractional Quantum Hall Effect

Heckmana and Luigi Tizzanob aDepartment of Physics and Astronomy, University of Pennsylvania, Philadelphia, PA 19104, U.S.A. bDepartment of Physics and Astronomy, Uppsala University, Box 516, SE-75120 Uppsala, Sweden E-mail: [email protected], [email protected] Abstract: We present a 6D generalization of the fractional quantum Hall effect involv- ing membranes coupled to a three-form potential in the presence of a large background four-form flux. The low energy physics is governed by a bulk 7D topological field theory of abelian three-form potentials with a single derivative Chern-Simons-like action coupled to a 6D anti-chiral theory of Euclidean effective strings. We derive the fractional conductivity, and explain how continued fractions which figure prominently in the classification of 6D su- perconformal field theories correspond to a hierarchy of excited states. Using methods from conformal field theory we also compute the analog of the Laughlin wavefunction. Com- pactification of the 7D theory provides a uniform perspective on various lower-dimensional gapped systems coupled to boundary degrees of freedom. We also show that a supersym- metric version of the 7D theory embeds in M-theory, and can be decoupled from gravity. Encouraged by this, we present a conjecture in which IIB string theory is an edge mode of a 10+2-dimensional bulk topological theory, thus placing all twelve dimensions of F-theory on a physical footing. -

Alessandro TOMASIELLO Rapporteur Abstract: The search for string theory vacuum solutions with non-trivial fluxes is of particular importance for the construction of models relevant for particle physics phenomenology. In the framework of the AdS/CFT correspondence, four-dimensional gauge theories which can be considered to descend from N = 4 SYM are dual to ten- dimensional field configurations with geometries having an asymptotically AdS5 factor. -
A Note on Six-Dimensional Gauge Theories
ILL-(TH)-97-09 hep-th/9712168 A Note on Six-Dimensional Gauge Theories Robert G. Leigh∗† and Moshe Rozali‡ Department of Physics University of Illinois at Urbana-Champaign Urbana, IL 61801 July 9, 2018 Abstract We study the new “gauge” theories in 5+1 dimensions, and their non- commutative generalizations. We argue that the θ-term and the non-commutative torus parameters appear on an equal footing in the non-critical string theories which define the gauge theories. The use of these theories as a Matrix descrip- tion of M-theory on T 5, as well as a closely related realization as 5-branes in type IIB string theory, proves useful in studying some of their properties. arXiv:hep-th/9712168v2 14 Apr 1998 ∗U.S. Department of Energy Outstanding Junior Investigator †e-mail: [email protected] ‡e-mail: [email protected] 0 1 Introduction Matrix theory[1] is an attempt at a non-perturbative formulation of M-theory in the lightcone frame. Compactifying it on a torus T d has been shown to be related to the large N limit of Super-Yang-Mills (SYM) theory in d + 1 dimensions[2]. This description is necessarily only partial for d > 3, since the SYM theory is then not renormalizable. The SYM theory is defined, for d = 4 by the (2,0) superconformal field theory in 5+1 dimensions [3, 4], and for d = 5 by a non-critical string theory in 5+1 dimensions [4, 5]. The situation of compactifications to lower dimensions is unclear for now (for recent reviews see [7, 8]). -

Review of Matrix Theory
SU-ITP 97/51 hep-th/9712072 Review of Matrix Theory D. Bigatti† and L. Susskind Stanford University Abstract In this article we present a self contained review of the principles of Matrix Theory including the basics of light cone quantization, the formulation of 11 dimensional M-Theory in terms of supersymmetric quantum mechanics, the origin of membranes and the rules of compactification on 1,2 and 3 tori. We emphasize the unusual origins of space time and gravitation which are very different than in conventional approaches to quantum gravity. Finally we discuss application of Matrix Theory to the quantum mechanics of Schwarzschild black holes. This work is based on lectures given by the second author at the Cargese ASI 1997 and at the Institute for Advanced Study in Princeton. September 1997 † On leave of absence from Universit`a di Genova, Italy Introduction (Lecture zero) Matrix theory [1] is a nonperturbative theory of fundamental processes which evolved out of the older perturbative string theory. There are two well-known formulations of string theory, one covariant and one in the so-called light cone frame [2]. Each has its advantages. In the covariant theory, relativistic invariance is manifest, a euclidean continuation exists and the analytic properties of the S matrix are apparent. This makes it relatively easy to derive properties like CPT and crossing symmetry. What is less clear is that the theory satisfies all the rules of conventional unitary quantum mechanics. In the light cone formulation [3], the theory is manifestly hamiltonian quantum mechanics, with a distinct non-relativistic flavor. -

D-Brane Actions and N = 2 Supergravity Solutions
D-Brane Actions and N =2Supergravity Solutions Thesis by Calin Ciocarlie In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy California Institute of Technology Pasadena, California 2004 (Submitted May 20 , 2004) ii c 2004 Calin Ciocarlie All Rights Reserved iii Acknowledgements I would like to express my gratitude to the people who have taught me Physics throughout my education. My thesis advisor John Schwarz has given me insightful guidance and invaluable advice. I benefited a lot by collaborating with outstanding colleagues: Iosif Bena, Iouri Chepelev, Peter Lee, Jongwon Park. I have also bene- fited from interesting discussions with Vadim Borokhov, Jaume Gomis, Prof. Anton Kapustin, Tristan McLoughlin, Yuji Okawa, and Arkadas Ozakin. I am also thankful to my Physics teacher Violeta Grigorie who’s enthusiasm for Physics is contagious and to my family for constant support and encouragement in my academic pursuits. iv Abstract Among the most remarkable recent developments in string theory are the AdS/CFT duality, as proposed by Maldacena, and the emergence of noncommutative geometry. It has been known for some time that for a system of almost coincident D-branes the transverse displacements that represent the collective coordinates of the system become matrix-valued transforming in the adjoint representation of U(N). From a geometrical point of view this is rather surprising but, as we will see in Chapter 2, it is closely related to the noncommutative descriptions of D-branes. A consequence of the collective coordinates becoming matrix-valued is the ap- pearance of a “dielectric” effect in which D-branes can become polarized into higher- dimensional fuzzy D-branes. -

This evolution in conception has followed the progressive discovery of a large web of dualities relating seemingly dissimilar string theories, such as theories of closed and oriented strings (type II theories), of closed and open unoriented strings (type I theory), and theories with built in gauge groups (heterotic theories). -
