Multi-entropy and the Dihedral Measures at Quantum Critical Points
The multi-entropy and dihedral measures are a class of tractable measures for multi-partite entanglement, which are labeled by the Rényi index (or replica number) $n$ as in the Rényi entanglement entropy. The purpose of this article is to demonstrate that these quantities are new useful probes of quantum critical points by examining concrete examples. In particular, we compute the multi-entropy and dihedral measures in the $1+1$ dimensional massless free scalar field theory on a lattice and i…

I dotarliśmy pod samo czoło lodowca svartisen. Szlak był trudny, głównie przez mokre kamienie, które szybko wyschły jak przestało padać. Wrażenia nie do opisania - szum i hałas całości, zapach, barwa lodu - niesamowite.

Na powrocie zaczęło świecić słońce i buty złapały przyczepność na skałach. Nad jeziorem jeszcze była herbata z termosu i powrót promem do busa.

Deza Cayley graphs from difference sets
In this note, we provide several constructions of Deza Cayley graphs over groups having a generalized dihedral subgroup. These constructions are based on a usage of (relative) difference sets.

Excellent papier.

Cell-Scale Dynamic Modeling of Membrane Interactions with Arbitrarily Shaped Particles
Modeling membrane interactions with arbitrarily shaped colloidal particles, such as environmental micro- and nanoplastics, at the cell scale remains particularly challenging, owing to the complexity of particle geometries and the need to resolve fully coupled translational and rotational dynamics. Here, we present a force-based computational framework capable of capturing dynamic interactions between deformable lipid vesicles and rigid particles of irregular shapes. Both vesicle and particle su…

Commuting Conjugacy Class Graphs of Finite Groups and the Hansen-Vukičević Conjecture
In this work, we compute the first and second Zagreb indices for the commuting conjugacy class graphs associated with finite groups. We identify multiple classes of finite groups whose commuting conjugacy class graphs are shown to satisfy the Hansen-Vuki{č}evi{ć} conjecture. Specifically, we prove that the conjecture holds for the commuting conjugacy class graphs of dihedral groups ($D_{2m}$), dicyclic groups, semidihedral groups, and various other two-generator groups. Moreover, we examine t…

Perfect codes in quartic Cayley graphs of generalized dihedral groups
For a graph $Γ=(VΓ,EΓ)$, a subset $D$ of $VΓ$ is a perfect code in $Γ$ if every vertex of $Γ$ is dominated by exactly one vertex in $D$. In this paper, we classify all connected quartic Cayley graphs on generalized dihedral groups admitting a perfect code, and determine all perfect codes in such graphs.
