Ricci-flat metrics from gauged linear -models without RG flow
Dmitri Bykov, Ondrej Hulik, Ulf Lindström +2
We investigate a class of Ricci-flat Kähler metrics on generalized conifolds constructed via gauged linear sigma models (GLSMs) with indefinite signature. By introducing shadow coo…
Gauss law constraint in A-theory branes
Machiko Hatsuda, Ondrej Hulık, William D. Linch +2
A-theory realizes U-duality symmetry by extending the string worldsheet to a higher dimensional brane worldvolume, in which the worldvolume and the spacetime belong to different re…
BCOV on the Large Hilbert Space
Eugenia Boffo, Ondřej Hulík, Ivo Sachs
We formulate the BCOV theory of deformations of complex structures as a pull-back to the super moduli space of the worldline of a spinning particle. In this approach the appearance…
BV Formalism and Partition Functions
Pietro Antonio Grassi, Ondrej Hulik
The BV formalism is a well-established method for analyzing symmetries and quantization of field theories. In this paper we use the BV formalism to derive partition functions of ga…
Non-Invertible T-duality at Any Radius via Non-Compact SymTFT
Riccardo Argurio, Andrés Collinucci, Giovanni Galati +2
We extend the construction of the T-duality symmetry for the 2d compact boson to arbitrary values of the radius by including topological manipulations such as gauging continuous sy…
Current Algebra and Generalised Cartan Geometry
Falk Hassler, Ondrej Hulik, David Osten
This article shows that the approach to generalised curvature and torsion pioneered by Polacek and Siegel [1] is a generalisation of Cartan Geometry -- rendering latter natural fro…
On Superparticles and their Partition Functions
Eugenia Boffo, Pietro Antonio Grassi, Ondrej Hulik +1
We describe a family of twisted partition functions for the relativistic spinning particle models. For suitable choices of fugacities this computes a refined Euler characteristics…
Scale and Conformal Invariance on (A)dS
Kara Farnsworth, Kurt Hinterbichler, Ondrej Hulik
We examine the question of scale versus conformal invariance on maximally symmetric curved backgrounds and study general 2-derivative conformally invariant free theories of vectors…
Exploring duality symmetries, multicriticality and RG flows at
Jeremias Aguilera Damia, Giovanni Galati, Ondrej Hulik +1
In this work, we study the realization of non-invertible duality symmetries along the toroidal branch of the conformal manifold. A systematic procedure to construct symmetry…
Y-algebroids and -generalised geometry
Ondrej Hulik, Emanuel Malek, Fridrich Valach +1
We define the notion of Y-algebroids, generalising the Lie, Courant, and exceptional algebroids that have been used to capture the local symmetry structure of type II string theory…
Unifying Approaches to Chiral Bosons
Alex S. Arvanitakis, Lewis T. Cole, Ondrej Hulik +2
Chiral bosons, or self-dual p-form fields, are ubiquitous in string theoretic contexts but are challenging to treat. Lagrangian constructions invariably introduce a complexity be i…
Super AKSZ construction, integral forms, and the 2-dimensional sigma model
Ondrej Hulik, Josef Svoboda, Fridrich Valach
We discuss a natural extension of the AKSZ construction to the case where the source is given by a supermanifold with a chosen integral form. We then focus on the special case with…
Doubled space and extended supersymmetry
Chris D. A. Blair, Ondrej Hulik, Alexander Sevrin +1
The doubled formulation of the worldsheet provides a description of string theory in which T-duality is promoted to a manifest symmetry. Here we extend this approach to $\mathcal{N…
Exceptional algebroids and type IIA superstrings
Ondrej Hulik, Fridrich Valach
We study exceptional algebroids in the context of warped compactifications of type IIA string theory down to dimensions, with . In contrast to the M-theory and type IIB…
Scale vs. Conformal Invariance at the IR Fixed Point of Quantum Gravity
Kara Farnsworth, Kurt Hinterbichler, Ondrej Hulik
We examine the question of scale vs. conformal invariance for the linearized Einstein-Hilbert action, which describes the IR fixed point of quantum gravity. In , although th…
On the Conformal Symmetry of Exceptional Scalar Theories
Kara Farnsworth, Kurt Hinterbichler, Ondrej Hulik
The DBI and special galileon theories exhibit a conformal symmetry at unphysical values of the spacetime dimension. We find the Lagrangian form of this symmetry. The special confor…
Information recovery from pure state geometries in 3D
Ondrej Hulik, Joris Raeymaekers, Orestis Vasilakis
It is a well-studied phenomenon in AdS/CFT that pure states often appear 'too thermal' in the classical gravity limit, leading to a version of the information puzzle. One e…
Multi-centered higher spin solutions from conformal blocks
Ondrej Hulik, Joris Raeymaekers, Orestis Vasilakis
Motivated by the question of bulk localization in holography, we study the problem of constructing multi-centered solutions in higher spin gravity which describe point particles in…
Multi-centered AdS solutions from Virasoro conformal blocks
Ondřej Hulík, Tomáš Procházka, Joris Raeymaekers
We revisit the construction of multi-centered solutions in three-dimensional anti-de Sitter gravity in the light of the recently discovered connection between particle worldlines a…
Non-minimal scalar multiplets, supersymmetry breaking and dualities
Fotis Farakos, Ondřej Hulík, Pavel Kočí +1
We study supersymmetry breaking in theories with non-minimal multiplets (such as the complex linear or CNM multiplets), by using superspace higher derivative terms which give rise…
