DAMTP 2009–52 A Connection between Twistors and Superstring Sigma Models on Coset Superspaces [PDF]
, 2009 We consider superstring sigma models that are based on coset superspaces G/H in which H arises as the fixed point set of an order-4 automorphism of G. We show by means of twistor theory that the corresponding first-order system, consisting of the Maurer ...

Cohomological Reduction of Sigma Models [PDF]
, 2010 This article studies some features of quantum field theories with internal supersymmetry, focusing mainly on 2-dimensional non-linear sigma models which take values in a coset superspace.

Topological couplings in higher derivative extensions of supersymmetric three-form gauge theories
Journal of High Energy Physics, 2019 We consider a topological coupling between a pseudo-scalar field and a 3- form gauge field in N = 1 $$ \mathcal{N}=1 $$ supersymmetric higher derivative 3-form gauge theories in four spacetime dimensions. We show that ghost/tachyon-free higher derivative

What is the geometry of superspace? [PDF]
Physical Review D, 1995 We investigate certain properties of the Wheeler-DeWitt metric (for constant lapse) in canonical General Relativity associated with its non-definite nature. Contribution to the conference on Mach's principle: "From Newtons Bucket to Quantum Gravity", July 26-30 1993, Tuebingen ...

Journal of High Energy Physics, 2018 We consider a four dimensional generalized Wess-Zumino model formulated in terms of an arbitrary Kähler potential KΦΦ¯ $$ \mathcal{K}\left(\varPhi, \overline{\varPhi}\right) $$ and an arbitrary chiral superpotential WΦ $$ \mathcal{W}\left(\varPhi \right)

Aspects of T-dually extended Superspaces [PDF]
, 2017 This dissertation is divided into three main parts where we derive various properties of the T-dually extended superspaces. In the first part we reformulate the manifestly T-dual description of the massless sector of the closed bosonic string, directly ...

Noncommutative Supergeometry and Physics [PDF]
, 2013 We present the project inside the IAP network concerning Noncommutative Supergeometry and Physics. We have introduced basic notions of noncommutative supergeometry, Hilbert superspaces, C*-superalgebras, and obtained nice applications in harmonic ...

The dark side of double-tensor multiplets
Journal of High Energy PhysicsWe explore the properties of a set of free double-tensor multiplets in N $$ \mathcal{N} $$ = 2 supersymmetry, focusing on their behavior within rigid superspace.

Radiation field on superspace [PDF]
, 1995 We study the dynamics of multiwormhole configurations within the framework of the Euclidean Polyakov approach to string theory, incorporating a modification to the Hamiltonian which leads to a Planckian probability measure for the Coleman parameters $α$ that allows $\frac{1}{2}α^{2}$ to be interpreted as the energy of the quanta of a radiation field on
