The Integral Decimation Method for Quantum Dynamics and Statistical Mechanics
We present a method to numerically evaluate functional integrals called integral decimation (ID). It constructs a separable decomposition of the integrand as a spectral tensor train (STT), a continuous generalization of the matrix product state. ID builds the STT by mapping the integrand to an auxiliary many-body wavefunction that evolves in time from an initially unentangled state. Each body-ordered term of the action corresponds to a quantum gate, applied to the state during its evolution. Th…

Feuerwerk vertreibt Störche im Landkreis Leipzig – der Nachwuchs verendet
Trauer in Thräna bei Borna: Ein illegales Feuerwerk hat zwei Weißstörche flüchten lassen. Ihr Nachwuchs ging zugrunde, kurz bevor er schlüpfen konnte. Kein Einzelfall im Landkreis. Dabei drohen hohe Strafen.

A novel test of gravity: Does spacetime geometry track matter density?
We propose a novel test of gravity that combines galaxy clustering with gravitational lensing. In general relativity, the evolution of matter density fluctuations and of the Weyl potential -- the sum of spatial and temporal distortions of the geometry -- are governed by the same growth function. In contrast, alternative theories of gravity that modify the relation between geometry and matter content can lead to differences in these two growths. Exploiting a recent method to directly measure the…

On the largest prime factor of quadratic polynomials
Let $x$ denote a sufficiently large integer. We show that the recent result of Grimmelt and Merikoski actually yields the largest prime factor of $n^2 +1$ is greater than $x^{1.317}$ infinitely often. As an application, we give a new upper bound for the number of integers $n \leqslant x$ which $n^2 +1$ has a primitive divisor.

Electron and gas temperature-driven chemistry during microdischarges formed in water vapour bubbles
Microdischarges formed in bubbles immersed in liquids are of interest for materials synthesis and chemical conversion applications in the frame of plasma-driven electrochemistry. A key challenge associated with controlling such processes is the limited understanding of the gas-phase chemical kinetics in these microdischarges. Due to their large electron densities, and high gas temperatures, both electron and gas temperature driven chemistry are likely to be important. Here, a 0-D modelling appr…
