Correlation functions in the CFT(d) / AdS(d+1) correspondence

- D. Freedman, S. Mathur, A. Matusis, L. Rastelli
- Physics
- 7 April 1998

Abstract Conformal techniques are applied to the calculation of integrals on AdS d +1 space which define correlators of composite operators in the superconformal field theory on the d -dimensional… Expand

Infinite Chiral Symmetry in Four Dimensions

- C. Beem, Madalena Lemos, P. Liendo, Wolfger Peelaers, L. Rastelli, B. V. Rees
- Mathematics, Physics
- 18 December 2013

We describe a new correspondence between four-dimensional conformal field theories with extended supersymmetry and two-dimensional chiral algebras. The meromorphic correlators of the chiral algebra… Expand

Tachyon potentials, star products and universality

- L. Rastelli, B. Zwiebach
- Physics
- 30 June 2000

We develop an efficient recursive method to evaluate the tachyon potential using the relevant universal subalgebra of the open string star algebra. This method, using off-shell versions of Virasoro… Expand

Classical solutions in string field theory around the tachyon vacuum

- L. Rastelli, A. Sen, B. Zwiebach
- Physics
- 19 February 2001

In a previous paper [hep-th/0012251] we proposed a simple class of actions for string field theory around the tachyon vacuum. In this paper we search for classical solutions describing D-branes of… Expand

Gauge Theories and Macdonald Polynomials

- Abhijit Gadde, L. Rastelli, S. S. Razamat, W. Yan
- Physics, Mathematics
- 17 October 2011

We study the $${\mathcal{N}=2}$$ four-dimensional superconformal index in various interesting limits, such that only states annihilated by more than one supercharge contribute. Extrapolating from the… Expand

The bootstrap program for boundary CFTd

- P. Liendo, L. Rastelli, B. V. Rees
- Physics
- 16 October 2012

A bstractWe study the constraints of crossing symmetry and unitarity for conformal field theories in the presence of a boundary, with a focus on the Ising model in various dimensions. We show that an… Expand

The 4d Superconformal Index from q-deformed 2d Yang-Mills

- Abhijit Gadde, L. Rastelli, S. S. Razamat, W. Yan
- Physics
- 19 April 2011

In this letter we describe a new powerful duality, relating physics in four and in two dimensions. We will argue that for a large class of four-dimensional superconformal gauge theories, non-trivial… Expand

Bootstrapping the superconformal index with surface defects

- D. Gaiotto, L. Rastelli, S. S. Razamat
- Physics
- 16 July 2012

A bstractThe analytic properties of the $ \mathcal{N}=2 $ superconformal index are given a physical interpretation in terms of certain BPS surface defects, which arise as the IR limit of… Expand

Ghost Structure and Closed Strings in Vacuum String Field Theory

- D. Gaiotto, L. Rastelli, A. Sen, B. Zwiebach
- Physics
- 14 November 2001

We complete the construction of vacuum string field theory by proposing a canonical choice of ghost kinetic term – a local insertion of the ghost field at the string midpoint with an infinite… Expand

Star algebra spectroscopy

- L. Rastelli, A. Sen, B. Zwiebach
- Physics
- 29 November 2001

The spectrum of the infinite dimensional Neumann matrices M11, M12 and M21 in the oscillator construction of the three-string vertex determines key properties of the star product and of wedge and… Expand
