Efficient Parallel Scheduling for Sparse Triangular Solvers
We develop and analyze new scheduling algorithms for solving sparse triangular linear systems (SpTRSV) in parallel. Our approach produces highly efficient synchronous schedules for the forward- and backward-substitution algorithm. Compared to state-of-the-art baselines HDagg and SpMP, we achieve a $3.32 \times$ and $1.42 \times$ geometric-mean speed-up, respectively. We achieve this by obtaining an up to $12.07 \times$ geometric-mean reduction in the number of synchronization barriers over HDag…

Spinless and spinful charge excitations in moiré Fractional Chern Insulators
Fractionally charged elementary excitations, the quasi-electron and quasi-hole, are one of the hallmarks of the fractional Chern insulator (FCI). In this work, we observe that spontaneous spin polarization in twisted MoTe$_2$ leads to multiple species of low-energy quasi-particles distinguished by their spin quantum numbers. We perform large-scale exact diagonalization (ED) calculations to investigate the nature of these excitations and develop a method to extract their fundamental energetic pr…

Manchmal gelingt es frühmorgens den #Tau im #Sonnenlicht im Bild einzufangen, aber meist geht etwas Brillianz verloren. Außerdem habe ich meist auch einen Filter auf dem #Objektiv.

I'm excited to learn more about the Mexican league. I want to watch more of their games and I hope this docu-series helps!

What the ...? Ich wundere mich jedes Mal, weil ich wie ein Depp husten muss, wenn ich durch den Stuttgarter Schlossgarten fahre, und jetzt postet @… was von "Platanenhusten".
Es ergibt alles einen Sinn!

Density of states correlations in Lévy Rosenzweig-Porter model via supersymmetry approach
We studied global density-of-states correlation function $R(ω)$ for Lévy-Rosenzveig-Porter random matrix ensemble~\cite{BirTar_Levy-RP} in the non-ergodic extended phase. Using extension of Efetov's supersymmetry approach ~\cite{MirFyod_non_Gauss} we calculated $R(ω)$ exactly in all relevant ranges of $ω$. At relatively low $ω\leq Γ$\, (with $Γ\gg Δ$ being effective mini-band width) we found GUE-type oscillations with period of level spacing $Δ$, decaying exponentially at the Thouless …
