Towards Systematics of Calabi-Yau Landscape for String Cosmology

George K. Leontaris, Pramod Shukla · 2026

In this review, we discuss the relevance and impact of studying Calabi-Yau threefolds in the context of global model building in string phenomenology. First, taking a phenomenologist-friendly approach…

Valuative independence for Calabi--Yau varieties

Harold Blum, Yuchen Liu · 2026

We construct valuatively independent bases for the space of sections of an ample line bundle on a log Calabi--Yau pair over a discretely valued field and the space of regular functions on an affine CY…

Spin-Induced Nonlinear Scalarization of Kerr Black Holes in Einstein-scalar-Gauss-Bonnet Gravity

Meng-Yun Lai, Hyat Huang, Jutta Kunz, Yun Soo Myung, De-Cheng Zou · 2026

We investigate spin-induced scalarization of Kerr black holes in an Einstein-scalar-Gauss-Bonnet (EsGB) model that does not admit a linear tachyonic instability of the scalar-free solution. The scalar…

Quantum Scalar Spin Chirality in Coplanar Kagome Antiferromagnets

Nanse Esaki, Gyungchoon Go, Se Kwon Kim · 2026

We theoretically demonstrate that quantum fluctuations inherent to antiferromagnets can generate scalar spin chirality at zero temperature even in coplanar ordered magnets. In a kagome antiferromagnet…

Monodromy action of mirror stops for toric Calabi-Yau surfaces

Michela Barbieri, Andrew Hanlon, Jeff Hicks · 2026

Mirror symmetry predicts an action by the fundamental group of a conjectural stringy K\"ahler moduli space on the derived category of an algebraic variety. For a toric variety, a model for this space …

Low mass scalars at $e^+e-$ colliders

Tania Robens · 2026

I briefly discuss the search for low mass scalars at Higgs factories as well as available models that render such scalars feasible, where I focus on new developments since the review presented in arXi…

Constraints on a Light Singlet Scalar from Combined Exotic Higgs Decays

F. Azari, M. Haghighat · 2026

We investigate the phenomenology of the Standard Model extended by a real gauge-singlet scalar field, focusing on exotic Higgs decay channels. For a light scalar mass in the range \(0 < m_{\phi} < 40\…

A Neural Network Method for Scalar Conservation Laws with Convergence Rates for Shock-Wave Solutions: extended version

Jiachuan Cao, Buyang Li, Hao Li · 2026

We introduce an entropy-compatible neural network method for scalar hyperbolic conservation laws based on a computable surrogate of the Kru\v{z}kov entropy residual. The proposed loss is designed to e…

Perfectoid splitting and global $+$-regularity for smooth hypersurfaces

Shou Yoshikawa · 2026

In this paper, we prove that smooth Calabi--Yau hypersurfaces of degree $d$ over complete unramified discrete valuation rings with residue characteristic $p$ are perfectoid split if $p$ is larger than…

Scalar-flat K\"ahler surfaces whose Weyl tensor annihilates the Ricci form

Andrzej Derdzinski, Sinhwi Kim, JeongHyeong Park · 2026

We conjecture that any scalar-flat K\"ahler surface in which the Weyl tensor acting on 2-forms annihilates the Ricci form must be either Ricci-flat or locally isometric to a Riemannian product of two …

On a group ring identity related to the Alon-Jaeger-Tarsi conjecture

Janos Nagy, Peter Pal Pach · 2026

In this note we formulate a conjecture about two group ring identities and prove that it would imply the Alon-Jaeger-Tarsi conjecture.…

Light sea-quark flavor asymmetry and angular momentum of the nucleon in a scalar-vector spectator model

Parashmani Thakuria, Madhurjya Lalung, Jayanta Kumar Sarma · 2026

We present a light-front spectator model that describes the proton as an active sea antiquark paired with a composite scalar-vector spectator. Using a spatial profile based on soft-wall AdS/QCD, we fi…

Exponentially improved quantum simulation of scalar QFT

Qing-Hong Cao, Ying-Ying Li, Xiaohui Liu, Liang-Qi Zhang, Ke Zhao · 2026

Quantum simulations of scalar quantum field theories (QFT) provide important benchmarks for demonstrating quantum advantage. We revisit digitization in the occupation basis, which is typically hindere…

A note on four dimensional Shrinking Gradient Ricci Solitons with Constant Scalar Curvature

Chen Wang, Guoqiang Wu · 2026

Let $(M^4, g, f)$ be a four-dimensional complete noncompact gradient shrinking Ricci soliton with the equation $Ric+\nabla^2f= \frac{1}{2}g$. If its scalar curvature is $1$, Cheng-Zhou \cite{Cheng-Zho…

Inflationary Scenarios in $f(Q,\phi)$ Gravity with Scalar Field Coupling

F. Mavoa, M.B. Barry, R. Ndioukane, M.G. Ganiou, F.K. Ahloui · 2026

In this work, we investigated several inflationary scenarios within the framework of modified $f(Q,\phi)$ gravity with a nonminimal coupling between the scalar field and the nonmetricity scalar. We fo…

Stable $2$-systoles, scalar curvature and spin$^c$ comass bounds

Simone Cecchini, Sven Hirsch, Rudolf Zeidler · 2026

We prove a sharp stable $2$-systolic inequality for complex projective space under the scalar curvature lower bound of the normalized Fubini-Study metric. If $M$ is diffeomorphic to $\mathbb{C}\mathrm…
