Superspace or One Thousand and One Lessons in Supersymmetry

- S. Gates, M. Grisaru, M. Roček, W. Siegel
- Physics
- 1 May 1983

The 1983 book, free at last, with corrections and bookmarks. From the original troff, but now with CM (TeX) fonts.

Twisted multiplets and new supersymmetric non-linear σ-models☆☆☆★

Abstract A new D = 2 supersymmetric representation, the twisted chiral multiplet, is derived. Describing spins zero and one-half, the twisted multiplet is used to formulate supersymmetric nonlinear… Expand

Hyperkähler metrics and supersymmetry

- N. Hitchin, A. Karlhede, U. Lindström, M. Roček
- Mathematics
- 1 December 1987

We describe two constructions of hyperkähler manifolds, one based on a Legendre transform, and one on a sympletic quotient. These constructions arose in the context of supersymmetric nonlinear… Expand

Duality, quotients, and currents

- M. Roček, E. Verlinde
- Physics
- 18 October 1991

We study the generalization of R → 1/R duality to arbitrary conformally invariant sigma models with an isometry. We show that any pair of dual sigma models can be represented as quotients of a… Expand

Partial breaking of global D = 4 supersymmetry, constrained superfields, and three-brane actions

- M. Roček, A. Tseytlin
- Physics
- 27 November 1998

We show that the connection between partial breaking of supersymmetry and nonlinear actions is not accidental and has to do with constraints that lead directly to nonlinear actions of the Born-Infeld… Expand

Self-interacting tensor multiplets in N = 2 superspace

- A. Karlhede, U. Lindström, M. Roček
- Physics
- 8 November 1984

Abstract We give the N = 2 superspace action for self-interacting tensor multiplets in four dimensions and discuss the relation to the harmonic superspace recently proposed by Galperin et al.

Scalar tensor duality and N = 1,2 non-linear σ-models

- U. Lindström, M. Roček
- Physics
- 1 August 1983

Using N = 1 superfields, we investigate the duality between chiral multiplets and tensor multiplets. We find that the relation can be expressed in terms of a Legendre transform. We use this relation… Expand

Hypermultiplets, hyperKähler cones and quaternion-Kähler geometry

- B. D. Wit, M. Roček, S. Vandoren
- Physics, Mathematics
- 24 January 2001

We study hyperkahler cones and their corresponding quaternion-Kahler spaces. We present a classification of 4(n − 1)-dimensional quaternion- Kahler spaces with n abelian quaternionic isometries,… Expand

Linearizing the Volkov-Akulov model

- M. Roček
- Physics
- 14 August 1978

The nonlinear realization of supersymmetry of Volkov and Akulov is related to a constrained linear realization in two and four dimensions.

Improved Methods for Supergraphs

- M. Grisaru, W. Siegel, M. Roček
- Physics
- 19 November 1979

We introduce some new techniques into superfield perturbation theory which allow considerable simplifications in calculations. As a result, we show that all contributions to the effective action can… Expand
