The cosmological constant in supergravity [PDF]
The European Physical Journal C, 2018 We propose a supersymmetrisation of the cosmological constant in ordinary $$N=1$$N=1 supergravity that breaks supersymmetry spontaneously by a constant Fayet-Iliopoulos (FI) term associated to a U(1) symmetry.

On the Geometric Approach to the Boundary Problem in Supergravity
Universe, 2021 We review the geometric superspace approach to the boundary problem in supergravity, retracing the geometric construction of four-dimensional supergravity Lagrangians in the presence of a non-trivial boundary of spacetime.

Simplicity of AdS supergravity at one loop [PDF]
Journal of High Energy Physics, 2019 We demonstrate the simplicity of AdS5× S5 IIB supergravity at one loop level, by studying non-planar holographic four-point correlators in Mellin space.

Modified Supergravity Phenomenology in Gravitational Waves Era
Universe, 2022 We discuss phenomenological aspects of modified supergravity (MSG) in gravitational wave (GW) physics. MSG naturally provides double inflation and primordial black holes (PBHs) as cold dark matter.

Loop Corrections to Supergravity on AdS_{5}×S^{5}. [PDF]
Physical Review Letters, 2017 We consider the four-point correlator of the stress-energy tensor multiplet in N=4 super Yang-Mills theory. In the planar limit and at large 't Hooft coupling, such a correlator is given by the corresponding holographic correlation function in IIB ...

Enhanced Separation Behavior of Metals from Simulated Printed Circuit Boards by Supergravity
Metals, 2022 Printed circuit boards (PCBs) contain valuable metals, epoxy resin, and glass fiber, resulting in them being considered as attractive secondary sources of metals.

Supersymmetric AdS Solitons, Ground States, and Phase Transitions in Maximal Gauged Supergravity
Particles, 2023 We review some recent soliton solutions in a class of four-dimensional supergravity theories. The latter can be obtained from black hole solutions by means of a double Wick rotation.

Supersymmetric domain walls in 7D maximal gauged supergravity
European Physical Journal C: Particles and Fields, 2019 We give a large class of supersymmetric domain walls in maximal seven-dimensional gauged supergravity with various types of gauge groups. Gaugings are described by components of the embedding tensor transforming in representations $$\mathbf {15}$$ 15 and

European Physical Journal C: Particles and Fields, 2021 We study supersymmetric $$AdS_4$$ A d S 4 black holes in matter-coupled $$N=3$$ N = 3 and $$N=4$$ N = 4 gauged supergravities in four dimensions. In $$N=3$$ N = 3 theory, we consider $$N=3$$ N = 3 gauged supergravity coupled to three vector multiplets ...
