Suppression of the superfluid Kelvin-Helmholtz instability due to massive vortex cores, friction and confinement

SciPost Physics
We characterize the dynamical instability responsible for the breakdown of regular rows and necklaces of quantized vortices that appear at the interface between two superfluids in relative motion.

SPLITTING LOOPS AND NECKLACES: VARIANTS OF THE SQUARE PEG PROBLEM

Forum of Mathematics, Sigma, 2020
Toeplitz conjectured that any simple planar loop inscribes a square. Here we prove variants of Toeplitz’s square peg problem. We prove Hadwiger’s 1971 conjecture that any simple loop in $3$-space inscribes a parallelogram.

Monopoles, strings, and necklaces in SO(10) and E 6

Journal of High Energy Physics, 2019
We employ a variety of symmetry breaking patterns in SO(10) and E 6 Grand Unified Theories to demonstrate the appearance of topological defects including magnetic monopoles, strings, and necklaces.

Dynamics of cosmic necklaces [PDF]

Nuclear Physics B, 2001
We perform numerical simulations of cosmic necklaces (systems of monopoles connected to two strings each) and investigate the conditions under which monopoles annihilate. When the total monopole energy is large compared to the string energy, we find that the string motion is no longer periodic, and thus the strings will be chopped up by self ...

UNDERSCREENED KONDO NECKLACE [PDF]

Modern Physics Letters B, 1992
It has been suggested recently by Gan, Coleman, and Andrei that studying the underscreened Kondo problem may help to understand the nature of magnetism in heavy fermion systems. Motivated by Doniach’s work on the S=1/2 Kondo necklace, we introduce the underscreened Kondo necklace models with S>1/2.

Sparse paving positroids

The American Journal of Combinatorics
Using Postnikov's Le-diagrams, decorated permutations, and Grassmann necklaces, we classify which positroids are sparse paving matroids. This allows us to enumerate sparse paving positroids, making connections to a known sequence involving the golden ...

Des msw nsw de Thoutmosis III à Deir el-Bahari

Études et Travaux (Institute des Cultures Méditerranéennes et Orientales de l'Académie Polonaise des Sciences), 2017
Fragments of several identical women holding sistrum and menat necklaces have been found at Deir el-Bahari. These representations were carved on sandstone, erased and recarved after the Amarna period.
