Five-loop four-point integrand of N=8 supergravity as a generalized double copy [PDF]

, 2017
We use the recently developed generalized double-copy procedure to construct an integrand for the fiveloop four-point amplitude of N = 8 supergravity.

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.

Supergravity from a Massive Superparticle and the Simplest Super Black Hole [PDF]

, 1997
We describe in superspace a theory of a massive superparticle coupled to a version of two dimensional N=1 dilaton supergravity. The (1+1) dimensional supergravity is generated by the stress-energy of the superparticle, and the evolution of the ...

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.

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.

Multi-Field versus Single-Field in the Supergravity Models of Inflation and Primordial Black Holes

Universe, 2021
We review the models unifying inflation and Primordial Black Hole (PBH) formation, which are based on the modified (Starobinsky-type) supergravity. We begin with the basic (Starobinsky) inflationary model of modified gravity and its alpha-attractor-type ...

Supergravity Solutions for BI Dyons [PDF]

, 1999
We construct partially localized supergravity counterpart solutions to the 1/2 supersymmetric non-threshold and the 1/4 supersymmetric threshold bound state BI dyons in the D3-brane Dirac-Born-Infeld theory.

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.
