Probing superfluidity with quantum vortex necklaces and Leggett's bounds

Physical Review Research
We theoretically investigate a binary Bose-Einstein condensate in which the majority component hosts a vortex necklace, whose vortex cores act as moving effective potential wells for the minority component.

Ranking Binary Unlabelled Necklaces in Polynomial Time [PDF]

Workshop on Descriptional Complexity of Formal Systems, 2022
Unlabelled Necklaces are an equivalence class of cyclic words under both the rotation (cyclic shift) and the relabelling operations. The relabelling of a word is a bijective mapping from the alphabet to itself.

Totally nonnegative Grassmannians, Grassmann necklaces, and quiver Grassmannians [PDF]

Canadian Journal of Mathematics - Journal Canadien de Mathematiques, 2021
Postnikov constructed a cellular decomposition of the totally nonnegative Grassmannians. The poset of cells can be described (in particular) via Grassmann necklaces.

Random Necklaces Require Fewer Cuts [PDF]

SIAM Journal on Discrete Mathematics, 2021
It is known that any open necklace with beads of $t$ types in which the number of beads of each type is divisible by $k$, can be partitioned by at most $(k-1)t$ cuts into intervals that can be distributed into $k$ collections, each containing the same ...

Gray code order for Lyndon words [PDF]

Discrete Mathematics & Theoretical Computer Science, 2007
At the 4th Conference on Combinatorics on Words, Christophe Reutenauer posed the question of whether the dual reflected order yields a Gray code on the Lyndon family. In this paper we give a positive answer.

Metastable soliton necklaces supported by fractional diffraction and competing nonlinearities. [PDF]

Optics Express, 2020
We demonstrate that the fractional cubic-quintic nonlinear Schrödinger equation, characterized by its Lévy index, maintains ring-shaped soliton clusters ("necklaces") carrying orbital angular momentum. They can be built, in the respective optical setting,

Necklace Maps [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2010
Statistical data associated with geographic regions is nowadays globally available in large amounts and hence automated methods to visually display these data are in high demand. There are several well-established thematic map types for quantitative data on the ratio-scale associated with regions: choropleth maps, cartograms, and proportional symbol ...
