Small Structures, Volume 6, Issue 7, July 2025.A new type of artificial spin ice (ASI) lattices, i.e., in the ASI system embedded in the perpendicular magnetic anisotropy (PMA) matrix, is proposed. The numerical simulations reveal a strong magnon–magnon coupling between the bulk second‐order mode of the ASI and the fundamental mode of the PMA matrix, supported by a pronounced anticrossing frequency

Geometry of orientifold vacua and supersymmetry breaking
Journal of High Energy Physics, 2021 Starting from a peculiar orientifold projection proposed long ago by Angelantonj and Cardella, we elaborate on a novel perturbative scenario that involves only D-branes, together with the two types of orientifold planes O ± and anti-orientifold planes O ¯

Supersymmetry Breaking and Dilaton Stabilization in String Gas Cosmology
, 2011 In this Note we study supersymmetry breaking via gaugino condensation in string gas cosmology. We show that the same gaugino condensate which is introduced to stabilize the dilaton breaks supersymmetry.

Preheating, Supersymmetry Breaking, and Baryogenesis [PDF]
Physical Review Letters, 1996 Fluctuations of scalar fields produced at the stage of preheating after inflation are so large that they can break supersymmetry much stronger than inflation itself. These fluctuations may lead to symmetry restoration along flat directions of the effective potential even in the theories where the usual high temperature corrections are exponentially ...

Dark Dimension With (Little) Strings Attached
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

Quadratic contributions of softly broken supersymmetry in the light of loop regularization
European Physical Journal C: Particles and Fields, 2017 Loop regularization (LORE) is a novel regularization scheme in modern quantum field theories. It makes no change to the spacetime structure and respects both gauge symmetries and supersymmetry.

Fermions and supersymmetry breaking in the interval
Physics Letters B, 2004 We study fermions, such as gravitinos and gauginos in supersymmetric theories, propagating in a five-dimensional bulk where the fifth dimensional component is assumed to be an interval. We show that the most general boundary condition at each endpoint of the interval is encoded in a single complex parameter representing a point in the Riemann sphere ...

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.

Heterotic − type I dual pairs, rigid branes and broken SUSY
Nuclear Physics B, 2020 The moduli space of toroidal type I vacua, which are consistent at the non-perturbative level, is composed of independent branches characterized by the number (0, 16 or 32) of rigid branes sitting on top of orientifold planes.
