Demonic constraints on supergravity models [PDF]

Physics Letters B, 1985
Abstract We consider renormalization group scaling of the CP -violating phases of softly broken supersymmetry. We show that unless A ( M X is real or close to zero, these phases are naturally large in conflict with the experimental bound on the dipole electric moment of the neutron (DEMON) d n .

Oxide Interface of Gallium‐Based Liquid Metals: Beneficial Bridge or Hidden Risk?

ChemistryEurope, EarlyView.
Discussion on oxide interfaces in gallium‐based liquid metals have concentrated on their properties, behaviors, and related applications. However, the molecular mechanisms underlying effects, as well as the differences between the presence and absence of the oxide layer, have been less thoroughly discussed.

Hyper-dilaton Weyl multiplet of 4D, N $$ \mathcal{N} $$ = 2 conformal supergravity

Journal of High Energy Physics, 2022
We define a new dilaton Weyl multiplet of N $$ \mathcal{N} $$ = 2 conformal supergravity in four dimensions. This is constructed by reinterpreting the equations of motion of an on-shell hypermultiplet as constraints that render some of the fields of the ...

Recent advances in boosting interfacial bubble dynamics with external fields

Droplet, EarlyView.
External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

On the Topology of the Inflaton Field in Minimal Supergravity Models [PDF]

, 2013
We consider global issues in minimal supergravity models where a single field inflaton potential emerges. In a particular case we reproduce the Starobinsky model and its description dual to a certain formulation of R+R^2 supergravity. For definiteness we

On AdS4 superspace and supergravity

Journal of High Energy Physics
In the N = 1 superspace, AdS4 supersymmetry is realized as the non-linear super coordinate transformations. The fermionic coordinates form a faithful non-linear representation of supersymmetry on their own.

The DNA of Calabi–Yau Hypersurfaces

Fortschritte der Physik, Volume 74, Issue 2, February 2026.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Supersymmetry and Supergravity: Phenomenology and Grand Unification

, 1993
A survey is given of supersymmetry and supergravity and their phenomenology. Some of the topics discussed are the basic ideas of global supersymmetry, the minimal supersymmetric Standard Model (MSSM) and its phenomenology, the basic ideas of local ...

On destabilizing divergences in supergravity models [PDF]

Physics Letters B, 1995
We show that, for standard N=1 supergravity coupled to chiral matter, if the Kahler potential has no terms linear in chiral superfields then none are generated through quad. div. one--loop corrections. If however =0 and susy is spontaneously broken, linear terms are present and new linear terms may be generated due to nonrenormalizable couplings in K ...

Global aspects of the space of 6D N = 1 supergravities [PDF]

, 2010
We perform a global analysis of the space of consistent 6D quantum gravity theories with N = 1 supersymmetry, including models with multiple tensor multiplets.
