Special Geometry and Space-time Signature [PDF]

open access: yes, 2017
We construct N=2 four and five-dimensional supergravity theories coupled to vector multiplets in various space-time signatures (t,s), where t and s refer, respectively, to the number of time and spatial dimensions. The five-dimensional supergravity theories, t+s=5, are constructed by investigating the integrability conditions arising from Killing ...

Physicochemical vs Electrochemical Technologies for Metal Recovery – Main Insights, Comparison, Complementarity and Challenges

open access: yesChemistry–Methods, Volume 5, Issue 3, March 2025.
Different electrochemical and physicochemical methods employed for metal recovery and removal from various sources are presented herein, along with their key performance indicators. The main strengths and weaknesses of each technology are discussed in a comparative manner, when possible.

Off-shell $N=2\to N=1$ reduction in 4D conformal supergravity [PDF]

open access: yes, 2019
We discuss $N=2\to N=1$ reduction in four dimensional conformal supergravity. In particular, we keep the off-shell structure of supermultiplets (except hypermultiplets). As we will show, starting with (almost) off-shell conformal supergravity makes the procedure simpler than that from $N=2$ Poincar\'e supergravity, which makes it easier to show the ...

Survey of Supergravities

open access: yes, 2023
A large class of supergravities in diverse dimensions are surveyed. This includes maximal supergravities, their general gaugings in the framework of embedding tensor formalism, supergravities with less than maximal supersymmetry, their matter couplings and general gaugings.

Double Copy From Tensor Products of Metric BV■‐Algebras

open access: yesFortschritte 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.

On N = 2 Truncations of IIB on T^{1,1} [PDF]

open access: yes, 2012
We study the N=4 gauged supergravity theory which arises from the consistent truncation of IIB supergravity on the coset T^{1,1}. We analyze three N=2 subsectors and in particular we clarify the relationship between true superpotentials for gauged ...

An Unconventional Supergravity [PDF]

open access: yes, 2001
We introduce and completely describe the analogues of the Riemann curvature tensor for the curved supergrassmannian of the passing through the origin (0|2)-dimensional subsupermanifolds in the (0|4)-dimensional supermanifold with the preserved volume form.

Geometric Relational Framework for General‐Relativistic Gauge Field Theories

open access: yesFortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract It is recalled how relationality arises as the core insight of general‐relativistic gauge field theories from the articulation of the generalized hole and point‐coincidence arguments. Hence, a compelling case for a manifestly relational framework ensues naturally.

New Advancements in AdS/CFT in Lower Dimensions

open access: yesUniverse, 2021
We review recent developments in the study of the AdS/CFT correspondence in lower dimensions. We start by summarising the classification of AdS3×S2 solutions in massive type IIA supergravity with (0, 4) supersymmetries and the construction of their 2D ...
