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 ...

Relic density of neutralino dark matter in supergravity models [PDF]
, 1997 We calculate the relic density $({\ensuremath{\Omega}}_{{\ensuremath{\chi}}_{1}^{0}}{h}^{2})$ of neutralino dark matter in supergravity models with radiative electroweak symmetry breaking, for values of the Higgs sector parameter $\mathrm{tan}\ensuremath{

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 ...

The two-loop five-particle amplitude in N $$ \mathcal{N} $$ = 8 supergravity
Journal of High Energy Physics, 2019 We compute for the first time the two-loop five-particle amplitude in N $$ \mathcal{N} $$ = 8 supergravity. Starting from the known integrand, we perform an integration-by-parts reduction and express the answer in terms of uniform weight master integrals.

Supersymmetric action for 6D (4, 0) supergravity
Journal of High Energy Physics, 2022 We give a linearized but otherwise complete supersymmetric action for N $$ \mathcal{N} $$ = (4, 0) supergravity in six dimensions, using a Kaluza-Klein-type 5 + 1 split of coordinates and fields.

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 .

Double Copy From Tensor Products of Metric BV■‐Algebras
Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.
