Dark Dimension With (Little) Strings Attached

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Modular forms and SL(2, ℤ)-covariance of type IIB superstring theory

Journal of High Energy Physics, 2019
The local higher-derivative interactions that enter into the low-energy expansion of the effective action of type IIB superstring theory with constant complex modulus generally violate the U(1) R-symmetry of IIB supergravity by q U units.

Foundations of Ghost Stability

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

Hyperelliptic families and 4d N = 2 $$ \mathcal{N}=2 $$ SCFT

Journal of High Energy Physics
We classify four dimensional N = 2 $$ \mathcal{N}=2 $$ SCFTs whose Seiberg-Witten (SW) geometries can be written as hyperelliptic families. By using special Kähler condition of SW geometry, we reduce the problem to one parameter quasi-homogeneous ...

Exploring the geometry of supersymmetric double field theory

Journal of High Energy Physics, 2022
The geometry of N $$ \mathcal{N} $$ = 1 supersymmetric double field theory is revisited in superspace. In order to maintain the constraints on the torsion tensor, the local tangent space group of O(D) × O(D) must be expanded to include a tower of higher ...

Double Copy From Tensor Products of Metric BV■‐Algebras

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.

SUSY breaking in monopole quivers

Journal of High Energy Physics, 2019
We study 3d monopole quivers, theories with product gauge groups interacting through monopole superpotentials and we observe that they are a natural setup for the study of the spontaneous breaking of 3d N $$ \mathcal{N} $$ = 2 supersymmetry.

Notes on Characterizations of 2d Rational SCFTs: Algebraicity, Mirror Symmetry, and Complex Multiplication

Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract S. Gukov and C. Vafa proposed a characterization of rational N=(1,1)$N=(1,1)$ superconformal field theories (SCFTs) in 1+1$1+1$ dimensions with Ricci‐flat Kähler target spaces in terms of the Hodge structure of the target space, extending an earlier observation by G. Moore.

On T-Duality and Supersymmetry

, 1995
The interplay between T-duality and supersymmetry in string theory is explored. It is shown that T-duality is always compatible with supersymmetry and simply changes a local realization to a non-local one and vice versa. Non-local realizations become natural using classical parafermions of the underlying conformal field theory.

Infinite-dimensional algebraic Spin $$ \mathfrak{Spin} $$ (N) structure in extended/higher dimensional SUSY holoraumy for valise and on shell supermultiplet representations

Journal of High Energy Physics, 2022
We explore the relationship between holoraumy and Hodge duality beyond four dimensions. We find this relationship to be ephemeral beyond six dimensions: it is not demanded by the structure of such supersymmetrical theories.
