Magnetic domains

- D. Harland, S. Palmer, C. Sämann
- Physics, Mathematics
- 30 April 2012

A bstractRecently a Nahm transform has been discovered for magnetic bags, which are conjectured to arise in the large n limit of magnetic monopoles of charge n. We interpret these ideas using string… Expand

Extended Riemannian Geometry I: Local Double Field Theory

- Andreas Deser, C. Sämann
- Physics, Mathematics
- 8 November 2016

We present an extended version of Riemannian geometry suitable for the description of current formulations of double field theory (DFT). This framework is based on graded manifolds, and it yields… Expand

Multiple M2-branes and generalized 3-Lie algebras

- S. Cherkis, C. Sämann
- Physics
- 4 July 2008

We propose a generalization of the Bagger-Lambert-Gustavsson action as a candidate for the description of an arbitrary number of M2-branes. The action is formulated in terms of N=2 superfields in… Expand

Fuzzy scalar field theory as a multitrace matrix model

- D. O'connor, C. Sämann
- Physics
- 17 June 2007

We develop an analytical approach to scalar field theory on the fuzzy sphere based on considering a perturbative expansion of the kinetic term. This expansion allows us to integrate out the angular… Expand

L∞‐Algebras of Classical Field Theories and the Batalin–Vilkovisky Formalism

- B. Jurčo, Lorenzo Raspollini, C. Sämann, M. Wolf
- Physics, Mathematics
- 26 September 2018

We review in detail the Batalin–Vilkovisky formalism for Lagrangian field theories and its mathematical foundations with an emphasis on higher algebraic structures and classical field theories. In… Expand

The Multitrace Matrix Model of Scalar Field Theory on Fuzzy CP^n

- C. Sämann
- Physics, Mathematics
- 24 March 2010

We perform a high-temperature expansion of scalar quantum field theory on fuzzy CP^n to third order in the inverse temperature. Using group theoretical methods, we rewrite the result as a multitrace… Expand

Quantized Nambu–Poisson manifolds and n-Lie algebras

- Joshua DeBellis, C. Sämann, R. Szabó
- Physics, Mathematics
- 19 January 2010

We investigate the geometric interpretation of quantized Nambu–Poisson structures in terms of noncommutative geometries. We describe an extension of the usual axioms of quantization in which… Expand

The topological B-model on fattened complex manifolds and subsectors of Script N = 4 self-dual Yang-Mills theory

- C. Sämann
- Physics
- 29 October 2004

In this paper, we propose so-called fattened complex manifolds as target spaces for the topological B-model. We naturally obtain these manifolds by restricting the structure sheaf of the = 4… Expand

The topological B-model on a mini-supertwistor space and supersymmetric Bogomolny monopole equations

In the recent paper [1], it was argued that the open topological B-model whose target space is a complex (2|4)-dimensional mini-supertwistor space with D3- and D1-branes added corresponds to a super… Expand

Quantization of flag manifolds and their supersymmetric extensions

We first review the description of flag manifolds in terms of Plucker coordinates and coherent states. Using this description, we construct fuzzy versions of the algebra of functions on these spaces… Expand
