Disordering a permutation symmetric system: revivals, thermalization and chaos
This study explores the effects of introducing a symmetry breaking disorder on the dynamics of a system invariant under particle permutation. The disorder forces quantum states, confined to the $N+1$ dimensional completely symmetric space to penetrate the exponentially large $2^N$ dimensional Hilbert space of $N$ particles. In particular, we focus on the quantum kicked top as a Floquet system of $N$ qubits, and use linear entropy, measuring single qubit entanglement, to investigate the changes …

Associated groups of symmetric quandles
In this paper, we investigate the structure of associated groups of symmetric quandles. We explore the relationship between the associated group of a symmetric quandle and that of its underlying quandle. A group-theoretic characterization of the associated groups of symmetric quandles is presented. Moreover, we prove that a symmetric quandle is embeddable if and only if its underlying quandle is embeddable. Finally, we determine the abelianizations of these associated groups.

Ukraine-Liveblog: ++ US-Senator Graham rechnet mit scharfen Sanktionen ++
Der republikanische US-Senator Graham zeigt sich in den tagesthemen zuversichtlich, dass scharfe US-Sanktionen gegen Moskau verabschiedet werden. Außenminister Wadephul betont, dass Europa und die USA den Druck auf Putin aufrechterhalten müssen.

I built myself a tear sheet section on my photography page.
Just a tiny thing to cure my impostor syndrome in photojournalism. But I'm kinda glad I have something remotely decent to showcase.
Hope I'll have reasons to update this page over time.

Noninvertible Gauge Symmetry in (2+1)d Topological Orders: A String-Net Model Realization
We develop a systematic framework for understanding symmetries in topological phases in 2+1 dimensions using the string-net model, encompassing both gauge symmetries that preserve anyon species and global symmetries permuting anyon species, including both invertible symmetries describable by groups and noninvertible symmetries described by categories. As an archetypal example, we reveal the first noninvertible categorical gauge symmetry of topological orders in 2+1 dimensions: the Fibonacci gau…

Mixed state concurrence for symmetric systems

Mixed state concurrence for symmetric systems
We present a method to quantify entanglement in mixed states of highly symmetric systems. Symmetry constrains interactions between parts and predicts the degeneracies of the states. While symmetry alone produces entangled eigenstates, the thermal mixed state (density) which contains all of the eigenstate densities weighted by their Boltzmann factors is not necessarily as entangled as the eigenstates themselves because generally the mixed state can be re-expressed as a sum over densities which a…

Simplicial methods in the resource theory of contextuality
We develop a resource theory of contextuality within the framework of symmetric monoidal categories, extending recent simplicial approaches to quantum contextuality. Building on the theory of simplicial distributions, which integrates homotopy-theoretic structures with probability, we introduce event scenarios as a functorial generalization of presheaf-theoretic measurement scenarios and prove their equivalence to bundle scenarios via the Grothendieck construction. We define symmetric monoidal …
