Vibration‐Induced Stabilization of Lithium Anodes: Synergistic Effects of Morphological and SEI Evolution

Advanced Science, Volume 12, Issue 26, July 10, 2025.
This study, for the first time, highlights the marvelous effect of mechanical vibration on the performance of lithium metal batteries. The authors demonstrate that vibration enhances the performance of lithium metal anodes through a synergistic effect: surface flattening at the macroscale and the formation of an interfacial layer that facilitates fast ...

N=2 supergravity models with stable de Sitter vacua [PDF]

, 2003
In the present talk I shall review the construction of N=2 supergravity models exhibiting stable de Sitter vacua. These solutions represent the first instance of stable backgrounds with positive cosmological constant in the framework of extended ...

Modeling General Asymptotic Calabi–Yau Periods

Fortschritte der Physik, Volume 73, Issue 7, July 2025.
Abstract In the quest to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures the authors initiate the general study of asymptotic period vectors of Calabi–Yau manifolds. The strategy is to exploit the constraints imposed by completeness, symmetry, and positivity, which are formalized in asymptotic Hodge ...

Superconformal Symmetry, NMSSM, and Inflation

, 2010
We identify a particularly simple class of supergravity models describing superconformal coupling of matter to supergravity. In these models, which we call the canonical superconformal supergravity (CSS) models, the kinetic terms in the Jordan frame are ...

Evidence for a family of SO(8) gauged supergravity theories [PDF]

, 2012
In this note we discuss the classification of duality orbits of N = 8 gauged supergravity models. Using tensor classifiers, we show that there is a one-parameter family of inequivalent SO(8) gauged supergravity theories.

Massive vector multiplet with Dirac-Born-Infeld and new Fayet-Iliopoulos terms in supergravity

Journal of High Energy Physics, 2018
We propose a four-dimensional N = 1 supergravity-based Starobinsky-type inflationary model in terms of a single massive vector multiplet, whose action includes the Dirac-Born-Infeld-type kinetic terms and a generalized (new) Fayet-Iliopoulos-type term ...

Electrodeposited Manganese Dioxides and Their Composites as Electrocatalysts for Energy Conversion Reactions

ChemSusChem, Volume 18, Issue 5, March 3, 2025.
This review focuses on the electrochemical synthesis of MnO2 materials and their composites and their application as electrocatalysts for OER and HER reactions for the conversion of renewable energy into chemical fuels. The electrocatalytic function of electrodeposited MnO2 for ORR and bifunctional ORR/OER for efficient operation of fuel cells and ...

New Precision Electroweak Tests in Supergravity Models [PDF]

, 1997
We update the analysis of the precision electroweak tests in terms of 4 epsilon parameters, $\epsilon_{1,2,3,b}$, to obtain more accurate experimental values of them by taking into account the new LEP data released at the 28th ICHEP (1996, Poland).

Updated constraints on the minimal supergravity model [PDF]

Journal of High Energy Physics, 2006
We provide an up-to-date analysis of the parameter space of the minimal supergravity model (mSUGRA). Novel features include the new central value of the top quark mass, an improved calculation of the masses of the supersymmetric particles and the neutral Higgs bosons, constraints from b to s \ell^+ \ell^- decays, and a careful treatment of the most ...
