Conformal invariance, supersymmetry and string theory

- D. Friedan, E. Martinec, S. Shenker
- Physics
- 1986

Covariant quantization of string theories is developed in the context of conformal field theory and the BRST quantization procedure. The BRST method is used to covariantly quantize superstrings, and… Expand

A New Hat For The c=1 Matrix Model

- M. Douglas, I. Klebanov, D. Kutasov, J. Maldacena, E. Martinec, N. Seiberg
- Physics
- 21 July 2003

We consider two dimensional supergravity coupled to $\hat c=1$ matter. This system can also be interpreted as noncritical type 0 string theory in a two dimensional target space. After reviewing and… Expand

The Conformal Field Theory of Orbifolds

- L. Dixon, D. Friedan, E. Martinec, S. Shenker
- Physics
- 1987

A prescription for the calculation of any correlation function in orbifold conformal field theory is given. The method is applied to the scattering of four twisted string states, which allows the… Expand

The Annular Report on Non-Critical String Theory

- E. Martinec
- Physics
- 18 May 2003

Recent results on the annulus partition function in Liouville field theory are applied to non-critical string theory, both below and above the critical dimension. Liouville gravity coupled to $c\le… Expand

Localized Tachyons and RG Flows

- J. Harvey, D. Kutasov, E. Martinec, G. Moore
- Physics
- 16 November 2001

We study condensation of closed string tachyons living on defects, such as orbifold fixed planes and Neveu-Schwarz fivebranes. We argue that the high energy density of localized states decreases in… Expand

On the relevance of tachyons

- J. Harvey, D. Kutasov, E. Martinec
- Physics
- 13 March 2000

We study condensation of open string tachyons using renormalization group flow in the worldsheet field theory. This approach leads to a simple picture of the physics of the nontrivial condensate.

AdS Dynamics from Conformal Field Theory

- T. Banks, M. Douglas, G. Horowitz, E. Martinec
- Physics
- 4 August 1998

We explore the extent to which a local string theory dynamics in anti-de Sitter space can be determined from its proposed Conformal Field Theory (CFT) description. Free fields in the bulk are… Expand

INTEGRABLE SYSTEMS AND SUPERSYMMETRIC GAUGE THEORY

- E. Martinec, N. Warner
- Physics
- 27 September 1995

Abstract After the work of Seiberg and Witten, it has been seen that the dynamics of N = 2 Yang-Mills theory is governed by a Riemann surface ϵ In particular, the integral of a special differential… Expand

D-branes and strings as non-commutative solitons

- J. Harvey, Per Kraus, F. Larsen, E. Martinec
- Physics
- 3 May 2000

The non-commutative geometry of a large auxiliary B-field simplifies the construction of D-branes as solitons in open string field theory. Similarly, fundamental strings are constructed as localized… Expand

Phenomenology and conformal field theory or can string theory predict the weak mixing angle

- T. Banks, L. Dixon, D. Friedan, E. Martinec
- Physics
- 11 April 1988

Abstract We show that the weak mixing angle θ w is the same for continuously connected classical vacua of the heterotic string which have chiral fermions in their massless spectra. We also show that… Expand
