Failure of the semi log canonical Abundance for compact K\"{a}hler threefolds

Swapnajit Das · 2026

In this article we show that the semi log canonical abundance for compact K\"ahler varieties fails in dimension $3$. More specifically we construct a counterexample of a compact K\"ahler (irreducible)…

Chiral Symmetry and Its Restoration in QCD

Teiji Kunihiro · 2026

Starting with describing the Dirac equation in an unconventional manner, we introduce the notion of chirality and show how chiralities are mixed in the massive Dirac particles.Then we discuss the appr…

The existence criterion of holomorphic discs for higher $A_\infty$ operations via minimal discs

Qiang Tan, Zuyi Zhang · 2026

The main theorem of the paper provides an existence criterion of holomorphic discs for higher $A_\infty$ operations. The key step is to show that if a minimal disc in a K\"ahler manifold with boundary…

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 …

Digital Simulation of Non-Hermitian Knotted Bands on Quantum Hardware

Truman Yu Ng, Yuzhu Wang, Wei Jie Chan, Ruizhe Shen, Tianqi Chen, Ching Hua Lee · 2026

Knots and links represent a fundamental motif of non-local connectivity that permeates the physical sciences from string theory to protein folds. While spectral braiding has been explored in two-band …

Scale-separated vacua with extended supersymmetry

Niccolo Cribiori, Fotis Farakos, Alexandros Zarafonitis · 2026

We propose the first examples of scale-separated vacua with extended supersymmetry. They arise as circle compactifications of four-dimensional vacua of massive type IIA supergravity with scale separat…

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 …

Microsecond-resolved electro-optic dual-comb spectroscopy in the 10~12.5 $\mu$m fingerprint region for radical kinetics

Pei-Ling Luo, I-Yun Chen · 2026

Dual-comb spectroscopy enables broadband, high-resolution measurements with microsecond temporal resolution, but extending this capability to the 10~12.5 $\mu$m molecular fingerprint region remains te…

Estimating the tail index of Pareto-type distributions from geometric records

Martin Alcalde, Raul Gouet, Miguel Lafuente, F. Javier Lopez, Gerardo Sanz · 2026

In this paper we develop a novel inferential approach based on geometric records for estimating the tail index of heavy-tailed distributions. We construct a maximum likelihood estimator for the Pareto…

A Volume-Price-Adjusted MACD Trading Strategy with Sensitivity Calibration for U.S. Equity Indices

Luyun Lin, Lixing Lin, Zhen Zhang, Moxuan Zheng, Yiqing Wang · 2026

Traditional moving average convergence divergence (MACD) trading rules are often constrained by signal lag and susceptibility to false signals. To address these limitations, this study develops a volu…

On Quantum Obstructions in Type IIA Orientifolds

Lukas Kaufmann, Timo Weigand, Max Wiesner · 2026

Quantum corrections can severely modify or even remove classical infinite distance limits in four-dimensional gravity theories with minimal N=1 supersymmetry. In this note we study this effect for inf…
