New higher-derivative invariants in N = 2 supergravity and the Gauss-Bonnet term
A bstractA new class of N = 2 locally supersymmetric higher-derivative invariants is constructed based on logarithms of conformal primary chiral superfields. They characteristically involve a
Rigid 4D N=2$$ \mathcal{N}=2 $$ supersymmetric backgrounds and actions
A bstractWe classify all N=2$$ \mathcal{N}=2 $$ rigid supersymmetric backgrounds in four dimensions with both Lorentzian and Euclidean signature that preserve eight real supercharges, up to discrete
Extended supersymmetric BMS3 algebras and their free field realisations
A bstractWe study N = (2, 4, 8) supersymmetric extensions of the three dimensional BMS algebra (BMS3) with most generic possible central extensions. We find that N - extended supersymmetric BMS3
Non-renormalization theorems and N = 2 supersymmetric backgrounds
A bstractThe conditions for fully supersymmetric backgrounds of general N = 2 locally supersymmetric theories are derived based on the off-shell superconformal multiplet calculus. This enables the
The resolution of an entropy puzzle for 4D non-BPS black holes
A bstractWe show the equality between macroscopic and microscopic (statistical) black hole entropy for a class of four dimensional non-supersymmetric black holes in N$$ \mathcal{N} $$ = 2
N=4 supersymmetric BMS3 algebras from asymptotic symmetry analysis
We consider three dimensional $N=4$ flat supergravity, with an abelian R-symmetry enhancing the gravitational phase space. We obtain the field configuration whose asymptotic symmetries at null
Super-BMS3 algebras from N=2$$ \mathcal{N}=2 $$ flat supergravities
A bstractWe consider two possible flat space limits of three dimensional N=1,1$$ \mathcal{N}=\left(1,\ 1\right) $$ AdS supergravity. They differ by how the supercharges are scaled with the AdS radius
N = 2 dilaton Weyl multiplet in 4D supergravity
A bstractWe construct the dilaton Weyl multiplet for N = 2 conformal supergravity in four dimensions. Beginning from an on-shell vector multiplet coupled to the standard Weyl multiplet, the equations
Higher derivative corrections to BPS black hole attractors in 4d gauged supergravity
A bstractWe analyze BPS black hole attractors in 4d gauged supergravity in the presence of higher derivative supersymmetric terms, including a Weyl-squared-type action, and determine the resulting
Synchronization properties of network motifs
An analytic method is proposed to measure the stability of the synchronous state (SSS) the subgraph displays and it is shown that, for undirected graphs, the SSS is correlated with the relative abundance, while in directed graphs the correlation exists only for some specific motifs.
