Ergodic Properties of Quantum Markov Semigroups
In this paper, we study the ergodic theorem for infinite-dimensional quantum Markov semigroups, originally introduced by Frigerio and Verri in 1982, and its latest version developed by Carbone and Girotti in 2021. We provide a sufficient condition that ensures exponential convergence towards the positive recurrent subspace, a well-known result for irreducible quantum Markov semigroups in finite-dimensional Hilbert spaces. Several illustrative examples are presented to demonstrate the applicatio…

Measurement of the branching fraction of $\psip \to \omega \eta \eta$

Measurement of the branching fraction of $\psip \to ωηη$
Using a sample of (2.712 $\pm$ 0.014)$\times 10^{9}$ $\psip$ events collected with the BESIII detector at the BEPCII collider in 2009, 2012, and 2021, the decay $\psip \to ωηη$ is observed for the first time. The branching fraction of the $ψ(3686)\toωηη$ decay is measured to be (1.65 $\pm$ 0.02 $\pm$ 0.21)$\times 10^{-5}$, where the first uncertainty is statistical and the second systematic. Clear structures associated with the well-established $ω(1420)$ and $f_{0}(1710)$ resonances are…

Trying to figure out why Gemini AI in Gmail is so very bad. It seems to not have access to all of my email and whatever RAG-like thing they are doing is very stupid.
Here's Gemini saying my oldest email matching some keywords in 2021 is from March 2021. If I explicitly tell it to look in February 2021, it finds it. There's only 11 emails that match in all of 2021, it's not like I'm blowing up the context window.

Uspol, genocide
In case you're wondering whether "political violence" is escalating in the U.S.A. right now, of *course* it is as we move into an era of concentration campus and domestic military deployments. But both domestic genocides and purges as well as political violence targeted at individual prominent figures has been a *constant* throughout American history, from gun duels fought between political rivals to massacres of Native Americans in order to steal their land, to pogroms against Catholics, to literal wars on local Black success and political participation, all dating back before the American Revolution to the beginning of colonization. Thanks to Wikipedia, here's a *small sampling* where I attempted to whittle things down to about one event per decade before recent times.

The Perturbation Theory Approach to Stability in the Scattered Disk

The Perturbation Theory Approach to Stability in the Scattered Disk
Scattered disk objects (SDOs) are distant minor bodies that orbit the sun on highly eccentric orbits, frequently with perhelia near Neptune's orbit. Gravitational perturbations due to Neptune frequently lead to chaotic dynamics, with the degree of chaotic diffusion set by an object's perihelion distance. Batygin et al. (2021) developed a perturbative approach for scattered disk dynamics, finding that, to leading order in semi-major axis ratio, an infinite series of $2:j$ resonances drives the d…

APCs and citation impact of Gold OA articles authored by Ukrainian scholars before and during Russia's full-scale war against Ukraine (2020-2023)

APCs and citation impact of Gold OA articles authored by Ukrainian scholars before and during Russia's full-scale war against Ukraine (2020-2023)
This study examines how Russia's full-scale war against Ukraine affected APCs, publishing patterns, and citation impact of Gold OA articles authored by Ukrainian scholars between 2020 and 2023. Data from Scopus covers articles published before (2020-2021) and after (2022-2023) the war's onset. Statistical analysis revealed a small but significant correlation between APC amounts and citation impact, though the effect size was minimal, suggesting higher APCs did not substantially boost citations.…

The moduli spaces of left-invariant statistical structures on Lie groups
In the context of information geometry, the concept known as left-invariant statistical structure on Lie groups is defined by Furuhata--Inoguchi--Kobayashi [Inf. Geom. (2021)]. In this paper, we introduce the notion of the moduli space of left-invariant statistical structures on a Lie group. We study the moduli spaces for three particular Lie groups, each of which has a moduli space of left-invariant Riemannian metrics that is a singleton. As applications, we classify left-invariant conjugate s…
