Chevalley formulae for the motivic Chern classes of Schubert cells and for the stable envelopes

arXiv, 2023
We prove a Chevalley formula to multiply the motivic Chern classes of Schubert cells in a generalized flag manifold $G/P$ by the class of any line bundle $\mathcal{L}_λ$. Our formula is given in terms of the $λ$-chains of Lenart and Postnikov. Its ...

Coherent Quantum Speed Limits

arXiv, 2024
We establish a comprehensive theoretical framework for coherent quantum speed limits (QSLs), deriving fundamental bounds on the rate of quantum evolution that explicitly isolate the contribution of quantum coherence. By applying Hölder's inequa...

Limits on the Primordial Black Holes Dark Matter with future MeV detectors

arXiv, 2024
Primordial black holes (PBHs) are a compelling candidate for Dark Matter (DM). There remain significant parameter spaces to be explored despite current astrophysical observations have set strong limits. Utilizing advanced MeV observation instruments,...

On the Frobenius fields of abelian varieties over number fields

arXiv, 2024
Let $A$ be a non-CM simple abelian variety over a number field $K$. For a place $v$ of $K$ such that $A$ has good reduction at $v$, let $F(A,v)$ denote the Frobenius field generated by the corresponding Frobenius eigenvalues. Assuming $A$ has connect...

Lower bounds on fibered Yang-Mills functionals: generic nefness and semistability of direct images

arXiv, 2024
The main goal of this paper is to generalize a part of the relationship between mean curvature and Harder-Narasimhan filtrations of holomorphic vector bundles to arbitrary polarized fibrations. More precisely, for a polarized family of complex projec...

The $\bar\partial$-problem on $Z(q)$-domains

arXiv, 2024
Given a complex manifold containing a relatively compact $Z(q)$ domain, we give sufficient geometric conditions on the domain so that its $L^2$-cohomology in degree $(p,q)$ (known to be finite dimensional) vanishes. The condition consists of the exis...

Cabello's nonlocality argument for multisetting high-dimensional systems and its experimental test

arXiv, 2024
Recent advancements have expanded Hardy's nonlocality arguments into multisetting and multidimensional systems to enhance quantum correlations. In comparison with Hardy's nonlocal argument, Cabello's nonlocal argument (CNA) emerges as ...

Exact upper bounds for the minimum sizes of strong and weak separating path systems of cliques

arXiv, 2024
We prove an upper bound of $n+9$ for the strong separation number of the complete graph $K_n$, and an upper bound of $n+1$ for its weak separation number. This improves on the previous best known bound of $(1+o(1))n$ for both cases.

Systematic errors in searches for nanohertz gravitational waves

arXiv, 2024
A number of pulsar timing arrays have recently reported preliminary evidence for the existence of a nanohertz frequency gravitational-wave background. These analyses rely on detailed noise analyses, which are inherently complex due to the many astrop...

Arena: Efficiently Training Large Models via Dynamic Scheduling and Adaptive Parallelism Co-Design

arXiv, 2024
Efficiently training large-scale models (LMs) in GPU clusters involves two separate avenues: inter-job dynamic scheduling and intra-job adaptive parallelism (AP). However, existing dynamic schedulers struggle with large-model scheduling due to the mi...

New and old Saito-Kurokawa lifts classically via $L^2$ norms and bounds on their supnorms: level aspect

arXiv, 2024
In the first half of the paper, we lay down a classical approach to the study of Saito-Kurokawa (SK) lifts of (Hecke congruence) square-free level, including the allied new-oldform theory. Our treatment of this relies on a novel idea of computing ran...

Mekler's Construction and Murphy's Law for 2-Nilpotent Groups

arXiv, 2024
Mekler's construction is a powerful technique for building purely algebraic structures from combinatorial ones. Its power lies in the fact that it allows various model-theoretic tameness properties of the combinatorial structure to transfer to t...

Raman resonances mediated by excitonic polarons in BiVO$_4$

arXiv, 2024
Excitonic polarons are quasiparticles formed by a Coulomb-bound electron-hole pair with strong coupling to lattice vibrations. Despite high fundamental interest in excitonic polarons, the experimental investigation of these particles remains challeng...
